Struthers-Dunn 219XDXP-120A Industrial Control Relay

The Struthers-Dunn 219XDXP-120A is a four-pole double-throw (4PDT) industrial control relay from the 219 Series, designed for plug-in installation with a compatible relay socket. It uses a 120 VAC coil and switches resistive loads up to 10 A at 120 VAC and 240 VAC, with operation specified for 50/60 Hz, making it suitable for control panels, automation equipment, and multi‑circuit switching in industrial environments. The 219 Series is a general‑purpose family known for electromechanical reliability and flexibility, including configurations that support multiple circuits from a single device. This model’s plug-in form factor simplifies field replacement and maintenance in tight panel layouts, enabling quick swaps without rewiring the base. Typical applications include machine control, process automation, interlock circuits, and other control tasks where compact, robust switching of several lines is required.
