Struthers-Dunn 219XDXP Relay

Struthers-Dunn 219XDXP Relay is a 219 Series industrial general-purpose relay with four Form C contacts in the XDX (4PDT) configuration, designed to switch four separate circuits in a compact plug‑in package. The model is offered with multiple coil voltages, including 24 VDC (as in the 219XDXP-24VDC variant) and 115/125 VDC (as in the 219XDXP-115/125VDC variant), giving flexibility for different control systems. This relay is commonly used in panels and automation racks where multiple circuits must be controlled from a single device, and it can be socket-mounted for straightforward panel replacement. Rated up to 10 A for resistive loads, the 219 Series supports typical control‑panel applications, with load ratings specified for various voltage and load types by the manufacturer’s data. Physical size for the four‑pole version is about 76.4 mm wide by 36.8 mm deep by 83.7 mm tall, a footprint compatible with standard relay sockets and compact enclosures. Optional configurations include a polycarbonate cover (CODE P), an indicator lamp (CODE L), and a manual actuator (CODE M), allowing customization for visibility and manual operation. In addition to standard industrial use, the 219 Series has nuclear-qualified variants that have undergone seismic and radiation testing for safety‑critical applications, reflecting Struthers-Dunn’s long history of rugged, mission‑critical relays.
