Description
Product Description
The Allen-Bradley 1771-OFE1 is a four-channel analog voltage output module designed for the PLC-5 and 1771 I/O platform. It provides precision analog signal generation for process control applications requiring stable voltage outputs with electrical isolation between channels.
Each output channel is individually isolated at 1000V, improving noise immunity and signal integrity in electrically demanding environments. The module supports multiple selectable output ranges, including 0–10 VDC, ±10 VDC, and +1 to +5 VDC, allowing flexible integration with a wide range of analog field devices.
Installed in a standard 1771 chassis, the 1771-OFE1 occupies a single slot and communicates directly through the PLC backplane. It uses 12-bit resolution conversion to ensure consistent and accurate analog output performance. The module is commonly deployed in legacy PLC-5 systems where precise voltage control is required for actuators, drives, and instrumentation.
