Omron K8DT-AS Series Monitoring Relay, 200A Maximum Current Sensed, 10A Minimum Current Sensed - K8DT-AS3CD

This monitoring relay provides single-phase current supervision for protection against both undercurrent and overcurrent conditions in industrial control systems. Designed for DIN-rail mounting, it offers a Compact control Interface and field-friendly terminals for integration into automation panels where current thresholds and short response times are required.

Features and Benefits:

• Detects currents from 10A to 200A for broad monitoring range
• Responds to faults with a 250 MS time delay for quick action
• SPDT contact provides versatile switching of control circuits
• Push-in terminals enable Rapid wiring and maintenance
• Operates across −20 °C to 60 °C for varied site environments
• Low power draw of 1.8 VA minimises supply loading

Applications

• Suitable for motor load supervision in industrial panels
• Ideal for detecting phase loss or reduced load conditions
• Used with control systems requiring fast trip signalling
• Can be used for process equipment current monitoring
• Suitable for retrofit into existing DIN-rail distribution boards

What contact current can it switch for control signalling?

The relay contacts are specified to handle currents in the range 10 mA to 200 mA for interfacing with downstream control devices.

Which environmental protection does it offer for panel mounting?

The enclosure carries an IP20 rating suitable for protection within enclosed control cabinets but not for exposed outdoor locations.

How is the unit secured within a control enclosure?

It attaches to standard DIN rails and presents a slim profile to conserve rail space.

Are there approvals relevant to industrial electrical installations?

It meets recognised standards including RoHS and the specified EN and UL control-relay standards for use in compliant systems.

Note

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