The K8DT-TH1CA is an active temperature monitoring relay from Omron’s K8DT series, accepting thermocouple or RTD inputs via push-in terminals. The SPDT relay output is rated 5 A at 250 VAC, sized for alarm or control circuits in panel applications. Supply voltage is fixed at 100–240 VAC; no delay timer on board, so the relay operates directly on the temperature threshold.
