Digital Parallel Port Controller Extension

The digital extension is capable of controlling devices connected to your parallel port, by taking supply from you computer. It does not need special supply. Optionally you can use the supply of an external power unit.
It can control independently 8 devices (output lines with 12 or 5 V up to 10W) and in addition to have 5 circuits as inputs (triggered at 2.5V).

The device can be used in home automation systems, small robotics applications or experimental units. Extremely simple to control, this device is excellent if you need quick results in your automation projects. With small size and simple software control it does not require professional knowledge to control it.

Also, we can produce a controller for 2 parallel ports which means it has 16 output lines and 10 input in one box. This device is capable of controlling small motors, relay systems, TTL electronic devices, and optically triggered devices. The system comes with a VB project software which can be modified to your needs.
