Omron K8DT-AW Series Monitoring Relay, 100 to 240V AC Supply Voltage, 0.1A to 5A Sensing Range - K8DT-AW2TA


This monitoring relay monitors single-phase current and signals overcurrent and undercurrent conditions within industrial control panels. It is designed for DIN-rail mounting in automation and electrical installations and operates from a wide AC supply range suited to varied mains environments.

Features and Benefits:


• Detects currents from 0.1A to 5A for precise protection and sensing
• Adjustable response to both overcurrent and undercurrent for flexible monitoring
• Single pole single throw contact provides a clear switching action
• Push-in terminals enable quick wiring and reduced installation time
• 250ms time delay prevents nuisance tripping from short transients
• Low power draw of 2.5VA minimises load on control supply

Applications


• Suitable for motor protection against stall and low-load conditions
• Ideal for monitoring current in single-phase distribution circuits
• Used with contactors to provide upstream current supervision
• Can be used for load-loss detection in heating and pump systems

What environmental temperature range can it operate within?


It functions reliably between -20°C and 60°C, allowing use in many plant and equipment rooms.

How is the device protected against ingress and where is it intended to be mounted?


The unit has an IP20 rating and is intended for installation on a DIN rail inside control enclosures.

Which standards cover its design and safety characteristics?


It is manufactured to meet EN 60947-5-1 and UL 60947-5-1 requirements and conforms to RoHS restrictions.

What are the Terminal and switching current specifics?


Connections use push-in terminals and the relay contact switching capability includes small sensing currents from 0.1mA up to 5mA.

Note

K8DT-AS allow use in either overcurrent or undercurrent mode.
K8DT-AW allow overcurrent and undercurrent monitoring simultaneously
