Allen-Bradley 800HC-PRH16G Power Relay Module

Allen-Bradley 800HC-PRH16G is a 30.5 mm pilot-light power module for 800H-series pushbutton assemblies, delivering a green LED indicator powered by an integrated transformer from 120 VAC. It is designed for Type 4/4X/13 environments, representing the rugged, sealed profile typical of Rockwell's 800H operator accessories and suitable for use inside control panels exposed to dust, moisture, or wash-down conditions. The module powers the pilot light while the associated 30 mm operator handles the control contacts, providing immediate, visible status of equipment such as conveyors, pumps, presses, and other automated machinery in industrial settings. Key specifications include a 30.5 mm footprint, LED green illumination, transformer-powered operation, 120 VAC input at 50/60 Hz, and compatibility with standard 800H modular pushbuttons to simplify panel assembly and maintenance. As part of the 800H family, the PRH16G improves visibility in busy panels and reduces wiring complexity by incorporating the power conversion in the module itself, helping technicians diagnose machine status at a glance in manufacturing or process environments.
