ANDI-PWR/AC 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.

ANDI-PWR/DC 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.

ANDI-SERVO 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.

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.

ANDI-RTD 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.
