Potter & Brumfield CKB-38-30010 Time Delay Relay

Potter & Brumfield CKB-38-30010 Time Delay Relay is a 24 VAC coil device designed to introduce a timed delay in electrical circuits. The part number CKB-38-30010, along with the UNMP designation, identifies its specific configuration within Potter & Brumfield’s line of time-delay relays. This relay is used in control panels and automation systems to create a defined delay between a triggering input and the relay’s output, enabling orderly sequencing, interlocks, or delayed activation in industrial equipment. With a 24 VAC coil, it is suited for low-voltage control circuits common in process automation, machine controls, and safety interlocks where precise timing is important. Typical applications include sequencing multiple components, providing safe startup delays, and coordinating interdependent control signals in manufacturing environments. Potter & Brumfield provides this unit as part of its line of industrial relays, designed to integrate into systems that rely on timed switching to achieve reliable process control and automation outcomes.
