Square D 9050JCK11V20 Plug-In Time Delay Relay

The Square D 9050JCK11V20 Timing Relay is a plug‑in, DPDT timer from the Square D JCK family that fits standard 8‑pin sockets for panel mounting. It provides on‑delay timing with an adjustable range of 0.1 to 10 seconds and a 10 A rating at up to 240 VAC, making it suitable for sequencing, interlocking, and start‑up delay applications in control panels. The relay offers two Form C outputs (DPDT: two normally open and two normally closed contacts) for flexible control of two circuits or devices. Timing is knob‑adjustable via an internal thumbwheel, enabling precise setting without external software, and the unit is designed for 240 VAC operation; similar JCK variants are available for 120 VAC or 110 VDC control voltages. UL recognition is achieved when used with the proper socket, such as the 8501NR, and the part is commonly distributed with an 8‑pin plug‑in base.
