TE Connectivity Time Delay Relay, Dpdt, 180S, 277Vac; Contact Voltage Vdc Potter&brumfield Te Connectivity CHD-38-30013

The CHD-38-30013 is a CMOS IC time delay relay in the CH series, configured for interval on timing mode with a 24VDC input, adjustable from 1 to 180 seconds using a knob. It features a 10A DPDT relay with silver-cadmium oxide contacts rated for 30VDC and 277VAC resistive loads. The device includes transient and reverse voltage protection, operates on filtered DC with ≤5% ripple, and has a white plastic octal enclosure with an 11-pin base. It supports timing tolerances of ±5% at the high end and ±10% delta time, with a typical release and recycle time of 125 ms. Operating temperature ranges from -10°C to +55°C, and storage spans -55°C to +85°C. Weight is approximately 170g.
