Schneider Electric 9050JCK17V20 General Purpose Relay

Schneider Electric’s Square D 9050JCK17V20 is a plug‑in, on‑delay timing relay (Type JCK) with two Form‑C DPDT contacts and a 17 VDC coil, designed for precise sequencing in control circuits. It handles up to 10 A at 240 VAC on the load side, uses an 8‑pin plug‑in base, and is UL‑listed when paired with the proper socket such as 8501NR. The timing function is adjustable from 0.3 to 30 minutes, allowing a defined delay before the output activates. Its enclosure measures about 104 mm × 61 mm × 43 mm and it weighs roughly 93 g, with dimensions and form factor documented by Schneider Electric. The 9050JCK family encompasses multiple coil voltages (including 11V–20V variants), enabling selection to match common control voltages in automation panels. In practice, it’s used for sequencing, machine timing, conveyor control, interlocking, and other control applications where a reliable, adjustable delay is required before switching loads.
