H1700 Series Digital I/O Boards

The H1700 series digital I/O products provide direct interface to industry standard solid-state relay mounting racks. Use the H1750 to control twenty four relays on one G4PB24 backplane. Use the H1770 to control up to sixty four relays on four PB16 backplanes.

Multiple H1700  digital I/O boards allow a host computer to control thousands of digital I/O points from one serial port.

The digital inputs accept signals up to +0-5Vdc without damage. The digital outputs are open-collector and will sink 15mA making them ideal for controlling solid state relays.
