DGH D1702 D1700 Digital I/O Module, 7 Inputs/8 Outputs/RS-485

DGH Corporation, D1702, D1700 Digital I/O Module, 7 Inputs/8 Outputs/RS-485

Features:

• Connect to solid state relays to sense AC and DC voltages
• User defines any bit as input or output
• Controls digital I/O individually or all at once
• No software initialization required-I/O startup stored in EEPROM
• 15, 24, 64 bit versions
• Host-free communications in continuous mode
• Up to 7936 I/O points on a single twisted pair of wires
• Compatible with all DGH products

The D1700 digital input output provide computer monitoring and control of industrial on/off signals. The modules provide fifteen I/O bits for sensing contact closures and controlling relays or annunciators.

The modules contain seven discrete digital inputs and eight open-collector digital outputs. The discrete input bits contain internal pull-up resistors allowing for direct connection of switches or contacts without the need for external components. The open-collector outputs can be used to control solid-state relays or annunciators. The outputs can be pulled up to +30Vdc and drive 30mA loads without damage. Refer to the D1000 documents for more information.
