Omron K8DT-TH2CA Temperature Monitoring Relay – 100–240VAC, 0–1700°C, Thermocouple Input, SPDT

The Omron K8DT-TH2CA is a temperature monitoring relay designed for precise over- and under-temperature control in industrial automation systems. Supporting multiple thermocouple input types (B, E, J, K, P, R, S, T), it enables accurate temperature measurement and control across a wide range of 0–1700°C.

Operating on a 100–240VAC supply voltage, this 17.5 mm-wide DIN rail-mounted relay provides an SPDT relay output for alarm, control, or safety interlock applications. Compact, easy to wire via push-in terminals, and engineered for high reliability, the K8DT-TH2CA is ideal for ovens, furnaces, heating systems, and industrial temperature monitoring.
