Product Description

​The Omron K8AK-TH11S is a compact temperature monitoring relay designed to oversee temperature variations within industrial processes, ensuring equipment protection and optimal performance. It accepts inputs from various temperature sensors, including thermocouples (K, J, T, E types) and resistance temperature detectors (Pt100, Pt1000), offering flexibility for diverse applications. The device features a slim 22.5 mm width, facilitating easy integration into control panels with limited space. Equipped with a single SPDT relay output rated for 5 A at 250 VAC, it provides reliable control for temperature-related alarms or system responses.
