Pluggable DPDT relay operating at 230V AC/DC input. Delivers 3A max switching current with integrated LED indicator and quick plug-in terminal block mounting.
The Phoenix Contact 2822419 (ST-REL4-KG230/21-21) is a general-purpose plug-in relay connector equipped with a miniature switching relay. Designed for medium to large load switching in industrial control systems, it features 2 changeover contacts (DPDT) and operates on a 230 V AC/DC input voltage. It includes a built-in light indicator for visual status monitoring and is engineered for quick plug-in mounting into compatible basic terminal blocks (such as the URELG 4 series). Rated for a maximum continuous switching current of 3 A and built to withstand a wide operating temperature range from -20 °C to 50 °C, it delivers reliable signal isolation and load control for automated manufacturing and power distribution applications.

Used in factory automation control panels to isolate 230V AC mains signals from low-voltage logic circuits. The plug-in design enables rapid maintenance and replacement without stripping or rewiring.
Prevents high-voltage electrical feedback into sensitive automated logic controllers while allowing rapid swap-outs during mechanical relay wear.
Acts as an interposing relay to trigger high-current HVAC motor contactors using a 230V control signal. The 3A rating switches the contactor coils, while the 2-PDT configuration allows simultaneous feedback to the building management system.
Provides a compact, reliable method to switch heavy inductive contactor coils and send isolated equipment status signals in commercial HVAC controls.
Integrates into the motor control circuitry of automated packaging lines. The DPDT contacts switch directional logic or brake engagement for auxiliary conveyor components operating on 230V power.
Ensures minimal line downtime during relay failure via quick plug-and-play terminal block integration in high-cycle packaging operations.
