The 32-Ch Pneumatic Valve Control Interface is a 32-output device that converts MIDI and OpenSoundControl messages to 24 VDC pulses. These pulses can be used to trigger electromagnetic valves and actuators or any device accepting 24 VDC control signals (trigs or gates). It is base on the Rabbit 3700 microcontroller and uses custom MOSFET transistor boards.
