Square D 9050JCK12V20 Solid State Timing Relay

Square D by Schneider Electric 9050JCK12V20 is a plug-in timing relay (Type JCK) with DPDT contacts (2 Form C) and an eight-pin socket, designed for industrial control panels. It provides an adjustable on-delay timing range from 0.3 to 30 seconds and a load current rating of 10 A at up to 240 VAC on the output, making it suitable for sequencing and interlocking in control circuits. The timing action is triggered by a control coil that can be energized from 120 VAC or 110 VDC, enabling compatibility with common automation circuits. The device uses a standard plug-in base for quick replacement in compatible Square D sockets. Typical applications include sequencing and interlocking in control panels, conveyors, and machine start-up delays, as well as HVAC-control circuits where a short, repeatable delay is required. The 9050JCK family is a cost-effective line of plug-in timing relays, and this model’s 0.3–30 s range and 240 VAC load rating provide a reliable timing solution for a variety of industrial automation projects.
