The ALLEN-BRADLEY 1771-OFE2B is a high-precision analog output module designed for the PLC-5 system, providing four dedicated 4-20mA signals for the control of field devices such as valves, actuators, and motor drives. With its robust electrical isolation and 12-bit resolution, this module ensures accurate signal reproduction and maintains system integrity by preventing ground loops and electrical interference between the controller backplane and sensitive process instrumentation.
