Schneider Electric SE 8501XO40V02 Control Relay

The Schneider Electric Square D 8501XO40V02 Control Relay is an electromechanical switching device used in industrial control systems to drive higher‑power loads from low‑power control signals. Designed for installation in control panels, automation systems, and machinery, it typically provides 4‑Form‑C contacts and a 24 V DC coil for switching logic circuits and interfacing loads such as contactors, solenoids, or indicator circuits. Key specs include a load rating of roughly 10 A at 250 VAC / 30 V DC (model dependent), mounting options for socket or panel mounting, termination via screw or plug‑in connections, and an optional coil status indicator; operating temperature is the standard industrial range. This relay is part of Schneider Electric's Square D family and is commonly used in motor control panels, HVAC systems, pump and conveyor controls, and general automation, with common replacements including Square D 8501FHG33V02, RXM2AB2BD, and Omron MY4N‑DC24.
