Allen-Bradley 1771-OFE2 Analog Output Module

Description

The Allen-Bradley 1771-OFE2 Analog Output Module is part of the Allen-Bradley 1771 product line, designed for industrial automation control systems. It features four independently isolated analog output channels, delivering stable 4-20 mA current output signals for reliable industrial control applications. Key technical specifications include 850 VDC isolation (1 second duration), a digital-to-analog converter (DAC) settling time of maximum 0.8 ms, backplane current draw of 1.50 amps, power consumption of 7.9 watts, heat dissipation of 26.9 BTU/hr, and a maximum adjacent slot power draw of 10 watts. The module occupies a single slot in any 1771 I/O chassis and uses the 1771-WC field wiring arm, with 12-bit binary digital resolution that supports conversion of raw data to engineering units such as degrees Celsius, degrees Fahrenheit, gallons per minute, and pounds per square inch. Ideal for controlling final control elements like variable frequency drives, dampers, louvers, and valves, it also enables proportional-integral-derivative (PID) controller output for analog loop automatic control, and can transmit signals to measurement, reception, and recording components such as signal isolators, signal converters, panel meters, and data loggers.
