Pulse Encoder Input & Triac Output Card
Click here to jump to ANDI-PWR/AC Specifications
The ANDI-PWR/AC is a compact PC/104 card featuring four powerful Triac outputs and two pulse encoder inputs. The board can be used for switching AC loads and reading encoder data. The Triacs act like semiconductor relays and the encoder inputs provide a system with motion or displacement information. The card is also equipped with a positioning logic making it especially useful for control of tilt/pan type of motors commonly used in CTV applications. All inputs and outputs on the card are isolated from the computer system.
The four Triac-switches on the card can be used for controlling AC loads up to 230VAC. The card is suitable for driving constant speed AC motors, lamps, solenoids, contactors, relays and much more. The Triac outputs can be individually controlled from software. All Triacs feature zero crossover voltage detection and a reliable snubistor circuitry, ensuring safe switching of inductive loads.
The ANDI-PWR/AC is equipped with inputs for two, industry standard, pulse encoders. The card interprets the encoders quadrature encoded, bi-phase position- or displacement information, using 11 bit up/down counters. The pulse signals from the encoders are processed thorough digital filters on the board, efficiently removing noise and transients, preventing false counts from occurring.
The ANDI-PWR/AC features two, user programmable, digital comparators that monitor the movement/displacement counts from the pulse encoders. The comparators can be programmed with values for a desired displacement or position. When the encoder count equals the user programmed value in a comparator, an interrupt will occur. This indicates that a desired position/displacement is found. This significantly simplifies a positioning task since the high speed real time processing is done in the hardware.
In addition to general purpose AC load switching and interfacing of encoders, the card is especially suitable for controlling tilt/pan type of AC motors commonly used in CTV applications. It is customary for these motors to have separate AC drive signals for moving two axes left, right, up and down. The Triacs on ANDI-PWR/AC can directly drive the AC motors. The axis movement or displacement feedback is taken from pulse encoders. The card can be programmed to function in an automatic mode. When the cards automatic mode is used with a tilt/pan motor, the onboard logic will decide without user intervention, which Triac and direction of movement to be activated when new tilt and pan coordinates are entered.

Optoisolated MOSFET Digital I/O Card
Click here to jump to ANDI-PWR/DC Specifications
The ANDI-PWR/DC is an eight channel power MOSFET card, designed for switching DC loads including lamps, relays, solenoids, DC- and stepper motors, magnetic valves and much more. Connection of these type of loads to a computer system requires optoisolation and overvoltage protection found in the industry proven ANDI-PWR/DC design.
The eight power MOSFET transistors at the cards output stages, are isolated from each other and the computer system, providing a high level of security. Each output features protection for transients and spikes generated by inductive loads such as DC-motors or relays. The isolation of all output channels will efficiently prevent harmful parasitic currents from occurring when switching loads connected to different power supplies or potentials.
Each MOSFET on the card, is a power device capable of sinking up to 1.5 amperes at 24 volts. The peak current is 6 amperes and absolute maximum voltage is 60 volts which ensures a good safe operating area. The low on-resistance of approximately 150 milliohms, result in a very low heat generation in the MOSFET. Eight ultrabright LED-lamps indicates clearly an active output channel.
The ANDI-PWR/DC card features eight non-isolated, TTL-level inputs. Each of the input lines have a 100 ohms resistance in series, in addition to a 10 kOhms resistance pulling the line down. This is a simple, yet very efficient way of increasing the cards inputs durability for electrostatical discharge.
The card also features an unique pre-load register, specifically designed for installations where exact deterministic performance is required. The pre-load register contains programmable "on" or "off" information, that is immediately transferred to the MOSFET output stage when triggered by a remote signal. The triggering signal can be a raising edge of TTL-level introduced at the cards control connector.

The ANDI-MM is a highly versatile multipurpose data acquisition card which conforms to the PC/104 standard. The card features 4 protected analog inputs, 2 analog outputs, 16 TTL-level inputs and 16 outputs with a drive capability of 20 mA. Its compact size and low power CMOS design allow it to be used in a variety of applications from stand-alone embedded systems to distributed process control and automation systems. It can even be used in battery powered, portable applications.
The ANDI-MM card's simultaneous sampling feature means it can be used in more applications. The simultaneous, matched sampling of its 4 analog inputs, result in an extremely low time difference between the channels. This is equivalent to having 4 analog-to-digital converters working in parallel. This makes it ideal for applications requiring relative phase information. Up to 4 ANDI-MM cards may be installed in per computer, allowing simultaneous sampling of up to 16 analog inputs.
The ANDI-MM is provided with a connector for various control signals. These signals may be used for remotely starting conversion, interrupt controlling, sharing reference voltages between multiple ANDI-MM's, interrupt daisy chaining in multiple card installations and more.
The analog interface can accept a voltage level of ±10 V and the outputs are capable of producing ±10 V in a one to one relationship with each other. This eliminates need for scaling calculations and translates directly into faster software performance. Other output voltages are available on request. The ANDI-MM is user-friendly, yet designed for heavy duty environments. Its 4-layer PCB has separate connectors for digital and analog interfaces.
Intelligent design of the digital interface allows each I/O signal to be tested in loopback by simply applying a jumperblock between input and output. Centrally located power supply pins on the digital interface connector protect the card in the event of an upside-down mounting of the ribbon cable.
Analog inputs are protected by high speed, transient suppressing diodes, and analog outputs are buffered through a reliable operational amplifier.

Click here to jump to ANDI-OPTO Specifications
The ANDI-OPTO is an industry proven, PC/104 multipurpose isolated digital input card. The card acts as an interface for various digital signals in industrial environments. The inputs accept a range from 5 to 48 volts.
The ANDI-OPTO features eight opto-isolated digital inputs and eight non-isolated digital outputs of TTL-level. State of the art electronics enables customer specific solutions to be implemented easily without added cost to the board. The card's architecture utilizes EPLD technology. This allows the card to be shipped upon request with extended features such asvarious counter functions, digital filtering and much more.
The ANDI-OPTO comes with standard digital inputs in its basic configuration. The inputs are isolated with industry proven optoisolators.
The card can be programmed to generate an interrupt when an input signal goes "high" or "low". Channels can also be masked to prevent interrupt generation. The interrupt signal can also be directed to the cards control connector. This signal can then be used as a trigger for various equipment or cards. The trigger signal can be used for starting an A/D conversion on
the ANDI-MM card and it can be used for triggering the pre-load register on ANDI-PWR/DC and much more.
The ANDI-OPTO has field wiring connectors at the inputs. These rugged connectors are spring-loaded, and endure the rigors of industrial environments.

Dual Servo Motor Controller
Click here to jump to ANDI-SERVO Specifications
The ANDI-SERVO is intended for driving and controlling two DC, and brushless DC, servo motors, as well as, other servomechanisms that provide quadrature incremental feedback signals. Both position and velocity motion control systems can be implemented using the ANDI-SERVO board.
The board features a dedicated motion control processor, a quadrature encoder input and a H-bridge PWM output driver stage for each channel. This makes a complete, two axis, closed loop motor control system on a single PC/104 compatible board. The board also features outputs for an external high power motor driver stage, to be used in high current motor applications.
To start a motion, the host computer downloads trajectory information ie. acceleration, velocity and target position values to the ANDI-SERVO board. The boards motion control processors calculates new demand or "set point" positions and combines these with the actual position feedback, to form an error signal. The error signal is fed to the boards PID (proportional, integral, derivative) control loop compensator. The PID loop compensator monitors constantly the error signal and adjusts the motors accordingly. The PID loop compensator can be parametrized to allow a system to be tuned for optimum performance in terms of accuracy, response time and overshoot.
For a load that varies during the movement, new coefficients can be downloaded to the PID loop compensator to update it at the moment when the load changes. All trajectory parameters except acceleration can also be updated while a movement is in progress.
The ANDI-SERVO features shorted load protection, a thermal warning flag and thermal shutdown to prevent damages to occur at fault conditions. The board features rugged field wiring connectors for all interface cabling.

Click here to jump to PowerFramer Specifications
The PowerFramer is an efficient halfsize PC-slotboard intended for color video frame capturing and image processing. The card has high computing power and is suitable for various image processing and enhancement tasks, including character recognition, machine vision, compression and much more.
The PowerFramer card has an ISA and a PC/104 bus interface, both 16 bit wide and interconnected. This allows the card to be used as a gateway between the two architectures: It can be installed in any desktop PC, and/or used together with any 16 bit PC/104-compatible CPU or module.
The PowerFramer digitizes images from six software selectable inputs, accepting PAL, NTSC and SECAM color video signals of S-VHS and Composite type. The images are digitized in real time and stored in the cards image RAM.
The card also features a Video Look Up Table (LUT), which enables real-time filtering and masking of incoming image data.
The PowerFramer is equipped with a 40 MHz digital signal processor. Programs can be written in 'C' and/or DSP Assembler and they can be downloaded from the host PC to the card. The card features 128 kWords of program memory and 1.5 MBytes of image memory - all zero wait state, with 20 ns access time. The PowerFramer is also equipped with general purpose digital I/O lines. The card has 8 digital output lines and 8 digital input lines, of which 3 in- and 3 out-lines are isolated by optoisolators. The I/O lines can also trigger an image capturing sequence. The digital I/O lines facilitates installations, and removes the need for added I/O boards in the system. The card also features a nonvolatile 256 byte EEPROM for storing user data and parameters.
Optional JPEG compression software is also available, as well as powerful third party image processing, analysis and enhancement software packages.

Isolated Instrumentation Preamplifier
Click here to jump to ANDI-RTD Specifications
The ANDI-RTD is an isolated instrumentation pre-amplifier card, to be used together with the ANDI-MM data acquisition card, or as a general purpose amplifier board. The board can be used as a signal conditioning unit for sensors of resistive type or as a sensitive general purpose pre-amplifier and current loop receiver.
ANDI-RTD features four inputs and one output. Each input is equipped with a high quality instrumentation amplifier and a constant current source, providing excitation for resistive type of sensors. Each input can also be equipped with a resistor, enabling the board to be used as a current loop receiver.
An onboard multiplexer selects one of the four input amplifiers to be connected thorough an isolation amplifier to the output stage. Up to four ANDI-RTD boards can be connected to a single ANDI-MM board. This creates a system with 16 isolated analog inputs.
The board is perfect for measuring temperatures with Pt100/Pt500 type of resistive sensors. Linearization and calibration software in 'C' is supplied with the board. Reading of a temperature is done by a single software call to a function returning the linearized value in degrees Celsius.
The board's inputs are differential. Connection of sensors is realized by a four wire method. This ensures that common mode hum and noise is efficiently removed from the measurements.
The sensors and signals connected to the board are isolated from the computer system at the output by the means of an isolation amplifier. The board is suitable for use in harsh industrial environments where isolation of signals and sensors is a prerequisite.
ANDI-RTD does not necessarily need to be mounted onto the PC/104 bus. It can be operated as a separate entity, serving as a field wiring unit, performing conditioning and isolation of the incoming signals.
