The Allen-Bradley 1771-OA/B is an 8-point discrete AC output module designed for use within the 1771 Universal I/O system, compatible with PLC-5 series programmable controllers. The module interfaces 120V AC user devices including motor starters, solenoids, pilot lights, and annunciators to the Allen-Bradley 1771 I/O chassis backplane. Operating voltage range is 92 to 138V AC at 47 to 63 Hz, with a current rating of 1.5 amps per output channel and a maximum of 6 amps per module. Backplane current draw is 210 mA at 5V DC. Eight onboard red status LEDs provide individual output indication, and one green LED confirms module activity. Onboard 2A, 250V AGC2 fuses protect each output circuit. The module installs in any 1771-A1B through 1771-A4B or later I/O chassis slot and connects to field devices via the 1771-WA field wiring arm. This unit carries part number 1771-OA/B, Series B. The item is presented in its original anti-static bag with ReMan Electronics inventory documentation and Alton Steel source paperwork enclosed. No box damage or signs of prior installation are visible. Country of origin is the United States per nameplate data on the label. Serial number is not visible through the bag.
