What is the B&R X20DO6321?

6 digital outputs

Sink connection

2-wire connections

24 VDC for signal supply

Integrated output protection

1-wire connection type with 6-pin terminal block

The module is equipped with 6 outputs for 1- or 2-wire connections. The outputs are designed for a sink circuit.

For continuous 1-wire wiring, the 6x X20 terminal block can be used. 2-wire wiring can be implemented with the 12x terminal block.
