Allen Bradley 1771-OFE2 Analog Output Module 1771OFE2

Description:

The Allen Bradley 1771-OFE2 Analog Output Module is used in PLC-5 industrial control systems for converting digital signals into analog output signals. Commonly installed in Allen-Bradley 1771 I/O chassis within PLC-5 systems used in process control, manufacturing, and automation environments. Maintenance teams, OEMs, and system integrators use this module for system control, retrofit, or replacement of legacy analog output modules.

Applications:

The Allen Bradley 1771-OFE2 is designed for process control applications requiring precise analog signal output such as controlling variable frequency drives (VFDs), valves, dampers, and other final control elements. It is widely used in manufacturing plants, water treatment facilities, and industrial automation systems where 4–20 mA signal transmission is required for PID control loops and instrumentation. The module enables reliable communication between PLC systems and field devices for accurate process regulation.
