Omron K8AK-TH12S 24VAC/DC Temperature Monitoring Relay – Thermocouple Input, 0–1700°C, SPDT

The Omron K8AK-TH12S is a temperature monitoring relay designed for precise control and safety in industrial heating and cooling systems. Supporting a wide range of thermocouple input types (B, E, J, K, P, R, S, T), it monitors over or under-temperature conditions from 0 to 1700°C with high accuracy.

Operating on a flexible 24VAC/DC power supply, this compact 22.5 mm-wide DIN-rail module provides a single SPDT relay output for temperature-based alarms or process shutdowns. The K8AK-TH12S is ideal for ovens, furnaces, process heaters, and thermal protection circuits in industrial automation systems.
