B&R X20cDO8332
8 digital outputs with 2 A Source connection 1-wire connections Power feed integrated in the module Integrated output protection This module is equipped with 8 outputs for 1-wire connections. The outputs are designed for a source circuit. The nominal output current is 2 A. The output supply is fed directly to the module. An additional supply module is not needed. There is no connection between the module and the I/O supply potential on the bus module.
