1771-OFCAllen-Bradley PLC-5 Analog Output Module

The 1771-OFC is a 12-bit analog output module designed for Allen-Bradley PLC-5 universal I/O chassis. It converts digital controller values into precise analog control signals, supporting 5 VDC or 15 VDC output configurations for industrial actuation devices. This module provides reliable analog control loop integration within PLC-5 rack environments.

Analog Conversion and Output Performance

The 1771-OFC utilizes a 12-bit resolution digital-to-analog architecture to provide accurate signal generation for connected field devices. It accommodates selectable voltage ranges of 5 VDC or 15 VDC, translating controller logic into stable analog outputs for proportional control valves, drives, and instrumentation.

System Installation and Configuration

The module mounts directly into any standard slot within a 1771 I/O chassis backplane. Field wiring connects through a compatible removable terminal block attached to the chassis, permitting module replacement without disturbing field wiring. Mechanical keying slots prevent incorrect module insertion into incompatible chassis slots.
