Asea Brown Boveri RK216263-AT Industrial Relay Module

ABB RK216263-AT auxiliary relay, variant A, is a 250 V DC coil device in ABB’s RK relay family that functions as a compact signaling relay. It provides six make contacts, enabling a single input to energize multiple independent circuit closures for status indication, interlock logic, or signal distribution within industrial control panels. As an auxiliary relay, it is intended to interface control logic with auxiliary circuits rather than switching high-power loads, making it a common companion to ABB automation gear in machine controls and panel assemblies. The RK216263-AT is typically used in applications where ABB equipment requires an isolated, switchable interface to downstream relays, indicators, or PLC inputs, enabling reliable, repeatable contact closures in demanding environments. Variant A specifies this model’s coil and contact configuration within ABB’s RK-series lineup, ensuring correct matching with compatible drivers and plug-in or rail-mount assemblies used in ABB control installations.
