Schneider Electric 8501XD Relay

Schneider Electric’s Square D 8501XD is a NEMA-style relay in the 8501 family (Type XD) designed for industrial control and machine-tool applications. This unit provides eight normally open contacts and is rated for up to 10 A resistive loads at 600 VAC, while the coil operates from 125 VDC, enabling DC control of higher-voltage circuits. The 8501XD uses plug-in contact cartridges for easy contact conversion or replacement, simplifying maintenance and expansion of control logic in a single, configurable base. As part of the Square D Harmony lineup, it combines compact construction with standardized contact configurations, making it suitable for interfacing DC control signals to line-power equipment in machines, conveyors, and automation panels.
