Allen-Bradley 1771-OFE1 PLC-5 Analog Output Module

Allen-Bradley 1771-OFE1 PLC-5 Analog Output Module is a four-channel analog output card for PLC-5 controllers, used to drive actuators and analog process equipment by generating voltage or current signals. Each channel provides a configurable analog output with 12-bit resolution, operable in voltage or current mode depending on configuration. The module is designed for 1771 I/O backplanes and can be installed in universal 1771 chassis such as 1771-A1B, 1771-A2B, 1771-A3B, or 1771-A4B, with communication to the PLC-5 via block transfer for Remote I/O. It does not supply loop power to loop-powered devices. Rockwell Automation discontinued the 1771-OFE1 as of March 4, 2021.
