Omron K8DT-TH1CD Temperature Monitoring Relay – 24VAC/DC, 0–999°C, Thermocouple & Pt100 Input, SPDT

The Omron K8DT-TH1CD is a compact temperature monitoring relay designed for accurate over- or under-temperature control in industrial systems. Supporting both thermocouple and Pt100/Pt1000 RTD inputs, it offers precise measurement across a 0–999°C range for process protection and thermal management.

Operating on a 24VAC/DC power supply, this 17.5 mm-wide DIN-rail mounted relay features a single SPDT output for alarm or shutdown applications. With its push-in terminal design, slim profile, and reliable operation, the K8DT-TH1CD is ideal for control panels, heating systems, and temperature-critical automation.
