Allen-Bradley 800F-XD7 Diode Module 600V 1A Rectifier

Allen-Bradley 800F-XD7 is a diode module (diode block) for lamp-check circuits in 800F push-button assemblies. It is a Series A accessory designated as 800F‑Brand or D7 (Sprecher + Schuh, S&S) variant, with a 600 V rating and 1 A current rating. The XD7 diode module is designed to be connected in the 800F circuitry, typically to the X3 and X4 terminals to form the lamp-check path, and is commonly sold as a diode block in a Standard Pack. This accessory supports lamp verification within the 800F ecosystem without affecting other control signals, making it suitable for applications where indicator lamps must be checked for operation in industrial control panels that use 800F devices, such as status indicators and fault-check workflows.
