English Datasheet

Omron K8DT-AS Series Monitoring Relay, 100 to 240V Supply AC Voltage, 5A Maximum Current Sensed - K8DT-AS2CA

This monitoring relay provides single-phase current supervision for control circuits in industrial installations. It monitors both overcurrent and undercurrent conditions and operates from a wide AC supply, making it suitable for inline protection and control tasks where accurate sensing of load current is required.

Features and Benefits:

• Detects currents from 0.1 A to 5A and safeguards against deviations
• Adjustable response delay of 250 MS to prevent nuisance tripping
• SPDT contact configuration for straightforward control switching
• Push-in terminals for quick, tool-free wiring and maintenance
• Low power draw of 2.5 VA reducing auxiliary supply burden
• Rated for ambient use between -20 °C and 60 °C for varied sites

Applications

• Suitable for monitoring motor supply current in production lines
• Ideal for phase loss and load imbalance surveillance in panels
• Used with control contactors to initiate protective interlocks
• Can be used for process equipment current verification in workshops

What mounting method is provided for panel installation?

It clips onto a DIN rail, enabling Compact panel mounting and easy repositioning without additional hardware.

How does the relay behave with brief current fluctuations?

The built-in 250 MS time delay filters transient spikes, allowing short disturbances to pass without triggering an output.

What contact currents can be switched directly by the unit?

The relay contacts can carry control currents as low as 0.1 A and up to 5A for direct interfacing with small loads.

Which ingress protection and approvals relate to electrical safety?

The housing is rated IP20 and the unit conforms to applicable EN and UL standards Plus RoHS compliance.

Note

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