ABB BKX024R 125VDC RXMM 1 RK 214 003 AN Auxiliary Relay

ABB BKX024R 125VDC RXMM 1 RK 214 003 AN Auxiliary Relay is a DC‑coil signaling accessory in ABB's RXM relay family, designed to extend the range of signaling and interlock options in industrial control circuits. The 125 V DC coil (nominal range 110–125 V DC) powers the unit from common control supplies, enabling compact signaling without tying up main power contacts. The RXMM 1 designation—paired with the RK 214 003 AN ordering code—refers to a 2 make and 4 break contact set, providing six distinct electrical paths (two normally open make contacts and four normally closed break contacts) that can be used to monitor, interlock, or signal status in a panel or machine. This auxiliary relay is intended for use where isolated signaling is required alongside primary contactors or protection relays, helping simplify wiring and improve fault isolation in control schemes. The BKX024R form factor and coil specification align with ABB's modular signaling approach, allowing straightforward integration with ABB automation components and with other RXM‑series relays in control assemblies. By delivering additional, isolated contacts from a single coil, the BKX024R RXMM 1 variant supports reliable, low‑load signaling in industrial environments while maintaining compatibility with ABB's broader product ecosystem.
