The Allen-Bradley 1771-OFE2 is a sophisticated analog output module belonging to the 1771 product series, notable for its four individually isolated output channels which deliver a 4-20 mA current signal. This module is expertly suited for managing Final Control Elements (FCE) including Variable Frequency Drives (VFDs), dampers, valves, and various instrumentation, further capable of supporting PID controller implementations to automate analog loops. Designed for seamless integration into any 1771 I/O chassis, the 1771-OFE2 requires no external power supply and occupies just a single slot, boasting a channel update time of up to 1.6 milliseconds per four channels for Natural Binary and a robust 850 VDC channel isolation. Additionally, it features an easy-to-replace wiring arm, advanced self-diagnostics with LED indicators, and robust overvoltage protection with 1500 Volts of optoelectrical isolation, ensuring system reliability and safety.
