Schneider Electric 9050 JCK16V20 Electrical Timing Relay

Square D (Schneider Electric) 9050JCK16V20 Timing Relay is a plug-in, on-delay timing module from the Harmony 9050 JCK family that mounts in standard control panels via NR sockets. It provides two Form-C DPDT outputs (a pair of normally open and normally closed contacts) that can switch loads rated up to 10 A at 240 VAC, enabling reliable sequencing and interlock timing in machines and conveyors. The timing range is adjustable from 0.1 to 10 minutes, allowing precise control of downstream processes after the trigger signal, with the device configured for plug-in installation and quick replacement in spare-lug panels. The model is the 16V20 variant and accepts a control coil rated for 120 VAC or 110 V DC, aligning with common automation cabinet practices in North America. Typical applications include motor starter sequencing, pump and valve actuation sequencing, conveyor start/stop delays, and other industrial control tasks where a compact, fixed-time delay is required in a modular timer relay.
