D1-20 – Digital module with 8 exchange relay outputs
The D1-20 module provides 8 digital outputs with changeover relay and LED status indicator.
The relays status is controlled by serial interface through modbus commands .
An internal watch-dog circuit ensures continuity of operation and force in the state ” off ” all outputs in case of interruption of communication : normally open safe state.
Type of interface (RS422 or RS485), communication protocol (Modbus ASCII or RTU) and address (1 to 31) can be set directly via DIP switches, the module is suited for mounting on DIN rail.
