Omron K8DT-TH1CA Temperature Monitoring Relay — 17.5 mm DIN Rail, Over/Under Temperature 0-999 °C/F, Thermocouple & PT100/PT1000 Input, SPDT Output, 100-240 VAC

The Omron K8DT-TH1CA is a compact and versatile temperature monitoring relay designed to safeguard industrial equipment from temperature irregularities. This 17.5 mm DIN-rail mounted relay supports over-temperature and under-temperature detection across a wide range of 0 to 999 °C / °F, using thermocouple (E, J, K, T) or resistance temperature detector (Pt100, Pt1000) inputs for high-accuracy sensing.

Powered from a 100-240 VAC supply, the unit features a single SPDT (Form C) relay output capable of switching control or alarm circuits in response to detected temperature conditions, helping prevent equipment overheating or thermal faults. The Push-in terminals simplify wiring and reduce panel build time, and the slim profile optimizes space in control enclosures.

Ideal for use in industrial control panels, heating systems, process automation, and thermal protection applications, the K8DT-TH1CA enhances safety and reliability by continuously monitoring temperature and triggering corrective action when preset thresholds are exceeded.
