Omron K8DT-TH Series Monitoring Relay, 20.4-26.4V Supply Voltage, 0-999°C Temperature Range - K8DT-TH1TD

This monitoring relay provides thermocouple-based temperature supervision for industrial control systems, offering on/off temperature control within a Compact DIN-rail mount package. It is intended for electrical and automation panels where temperature thresholds must be detected and switched, supporting both DC and AC supply options at nominal 24 V.

Features and Benefits:

• SPST contact rated 10 A for direct load switching and simple control
• Thermocouple input covering 0-999 °C for wide-range temperature detection
• Push-in terminals for fast wiring and reduced installation time
• Accepts 20.4-26.4V DC/AC supply for flexible power arrangements
• IP20 protection enabling use inside enclosed control cabinets

Applications

• Suitable for monitoring heating elements in production equipment
• Ideal for temperature alarm signalling in electrical panels
• Used for on/off control of fans and cooling systems in enclosures
• Can be used for safety interlocks where thermocouple feedback is required

What ambient temperatures can it tolerate in operation?

It will operate reliably between -20 °C and 60 °C, accommodating typical indoor industrial environments.

How is it mounted within control equipment?

It clips onto a standard DIN rail for secure and repeatable installation.

What approvals support its use in regulated installations?

It carries EN 61326-1, EN 61010-1, UL 61010-1 and RoHS conformity for relevant electrical and emissions standards.

How large is the unit for panel layout planning?

The relay occupies a slim 17.5mm width and has a 90mm height and 90mm depth for space calculations.
