Allen-Bradley 1756-OF6CI/A is a six-channel isolated analog output module for ControlLogix systems. Each channel provides a 4-20 mA current output with galvanic isolation of 250 V continuous between outputs and the controller, using a 20-pin interface that plugs into the 1756 backplane. The module supports a 0-21 mA output range with 13-bit resolution across the full scale, enabling precise control of process devices and actuators in industrial automation. Typical applications include driving valves, proportional actuators, and other 4-20 mA loads within a ControlLogix system.
