8 Digital Inputs / 8 Digital Outputs
8DI/8DO (8 Digital Inputs / 8 Digital Outputs) is a module, which contains 8 isolated digital inputs with common grounding lead and 8 isolated outputs. The module is equipped with a modbus EIA/TIA 485 line interface.
8DI/8DO is both hardware and software configured. There are switches to set the communication parameters and modbus address. Connected software than can configure communication line watchdog. This function automatically switches outputs to predefined states, when communication is lost.
States of outputs are shown on panel. Module contains blocking input “Relay-Enable”, which disconnects supply voltage of output relays.
In FARCOM system is the 8DI8DO module usually put on the subsidiary RS485 line, which is mastered by a MPM module. There can be connected up to 4 8DI8DO modules to one MPM module.
