Product Overview
The Allen-Bradley 1771-OFE3 is a Bulletin 1771 PLC-5 analog output module designed to convert digital values into four isolated differential current outputs (0-50 mA). It draws power from the 1771 I/O chassis backplane and occupies a single slot. The module supports both Natural Binary and 4-digit BCD scaling, block transfer data functions (BTW/BTR), and includes conformal coating for protection. 1771-OFE3 integrates in industrial control systems to drive actuators, positioners, signal converters, and recording devices.
