ABB HK1-11K Industrial Control Relay Module Series

ABB HK1-11K is a side-mounted auxiliary contact block designed to attach to ABB MS132-K motor starters, adding an extra signaling channel with 1 normally open (NO) and 1 normally closed (NC) contact (1S+1Ö). It uses Push-In terminals for fast, secure wiring and is intended for right-side mounting on the starter assembly, enabling compact installation in control panels. The accessory is cataloged under the HK1 family with the specific part number 1SAM201902R1201 and the order code SK111K, making procurement straightforward alongside the MS132-K line. By providing an independent NO/NC pair, HK1-11K supports interlocking, status signaling, and auxiliary feedback in industrial control circuits, helping to simplify wiring schemes and improve reliability in motor-control applications.
