English Datasheet

Omron K8DT-TH Series Monitoring Relay, +1800°C Maximum Temperature Monitoring, 10A Contact Current - K8DT-TH2TD

This monitoring relay provides temperature on/off control for thermocouple inputs in industrial panels and control cabinets. Designed for DIN-rail mounting with push-in wiring, it accepts low-voltage supply and delivers a single-pole switching output suitable for thermal control tasks across a wide process range. Its construction supports standard industrial environments while fitting into Compact control layouts.

Features and Benefits:

• Monitors temperatures up to 1800°C enabling high-range thermocouple use
• Accepts supply of 20.4-26.4V DC/AC for flexible power options
• SPST contact rated 10 A for direct control of small loads
• Push-in terminals speed installation and reduce wiring time
• IP20 enclosure suitable for protected cabinet installations

Applications

• Suitable for thermocouple temperature relay 0-1800°C process loops
• Ideal for DIN-rail temperature monitoring relay in control panels
• Used with industrial thermocouple controller IP20 conveyor systems
• Can be used for SPST 10 A monitoring relay Omron heater control
• Used for Compact 17.5mm thermocouple relay PLC peripheral racks

What ambient conditions can it operate within?

It functions reliably between -20°C and 60°C ambient, matching typical indoor plant-room environments.

How does the relay Interface with temperature sensors?

It is designed for thermocouple input and provides on/off control based on configured setpoints for heating or cooling control loops.

What safety standards does it conform to for electrical installations?

The unit is built to meet EN 61010-1 and UL 61010-1 requirements and is also EN 61326-1 and RoHS compliant for electromagnetic and materials regulations.

How Compact is the device for dense panel layouts?

The relay occupies a narrow 17.5mm DIN-rail width to maximise space efficiency in control panels.

What switching behaviour can be expected for connected loads?

The single-pole contact provides straightforward open/close switching at up to 10 A, suitable for direct control of small heaters and signalling devices.
