The Struthers‑Dunn 219XBX281 Relay is a 219 Series industrial plug‑in relay featuring a 48 VDC coil and DPDT (two Form C) contacts for switching two independent circuits in control panels and machinery. The 219XBX family provides plug‑in reliability in industrial environments, with the 281 variant documented for a 125 VDC load of 1 A (Make & Carry) when used in DC circuits. This unit is designed for industrial and nuclear plug‑in applications, offering rugged construction and compatibility with Struthers‑Dunn sockets for straightforward installation in automation systems. When integrated into a panel, it enables dual‑circuit control logic and interlocking schemes while maintaining a compact footprint typical of the 219 Series.
