Schneider Electric 8501HO-80 AC Control Relay

Schneider Electric’s Square D 8501XO80-series NEMA Type X AC control relay is a compact, eight-form-A (8 NO) relay designed for machine‑tool and automation-panel control. It provides eight normally open contacts for multiplexed signaling or interlock functions and is rated at 10 A resistive at 600 VAC, making it suitable for control-power switching in industrial circuits. The 8501XO80 family offers multiple coil voltages to fit common control systems, including 110/120 VAC at 50/60 Hz (8501XO80V02), 220/240 VAC at 50/60 Hz (8501XO80V03), 208 VAC (8501XO80V08), and 125 VDC (8501XUDO80V63). Marketed under Square D by Schneider Electric, these relays are intended for use in machine tools and automation panels where reliable signaling and electrical isolation are required. As a Type X NEMA relay, this device supports robust operation in industrial environments and provides a convenient, panel‑mountable solution for coordinating multiple control signals from a single relay.
