Allen-Bradley 1771-OMD PLC-5 Digital AC Output Module

Description

The Allen-Bradley 1771-OMD PLC-5 Digital AC Output Module is a fused digital output unit from the 1771 series, designed for industrial automation control systems. It installs in a single slot of a 1771 I/O chassis, integrating with other I/O components to form a complete control system for operating external industrial devices. The module features a modular structure, enabling easy installation, removal, and maintenance, and is intended for control room installation, suitable for integration with other automation equipment in stable control room environments.

Key technical specifications include 16 digital AC outputs, supporting an output voltage range of 184 to 250V AC at 47 to 63Hz, compatible with common industrial AC power environments. Each output delivers a continuous current of 2A, with a total module current capacity exceeding 8A. It supports a surge current of 25A per output for 100ms, repeatable once per second, with identical surge ratings for the entire module. At 220V AC (60Hz), each output requires a 10mA hold current to remain activated, and has a maximum voltage drop of 1.5V at 2A output current. Additional performance details include a 4mA leakage current per output in the off state at 220V AC, with signal delay times of 10ms for turn-on and 8.3 to 9.1ms for turn-off at 60Hz.
