Omron K8DT-AW Series Monitoring Relay, 100 to 240V Supply AC Voltage, 0.1A Minimum Current Sensed - K8DT-AW2CA

This monitoring relay provides electrical phase monitoring and current sensing for single-phase control systems, protecting equipment by detecting both undercurrent and overcurrent conditions. It accepts a wide supply range and is designed for DIN-rail mounting in industrial control panels, offering a Compact footprint for space-constrained installations.

Features and Benefits:

• Detects 0.1A to 5A ranges to protect motor loads • SPDT contact offers simple changeover switching capability • 100-240V supply supports flexible power sources • 250ms time delay prevents nuisance tripping during transients • Push-in terminals enable Rapid wiring and serviceability • Power consumption 2.5VA minimises panel loading

Applications

• Suitable for monitoring motor supply current in conveyor systems • Ideal for detecting phase-related faults in pump control cabinets • Used with manufacturing machinery for load-loss detection • Can be used for preventative alarm signalling in HVAC panels

What contact switching currents can I expect for control signalling?

The relay provides switching capability at very low currents for signalling, specified down to 0.1mA and up to 5mA for relay contact current.

How does the device cope with temperature variations in plant rooms?

It is rated to operate between -20°C and 60°C, allowing use across typical industrial temperature ranges.

What mounting and enclosure protection does it require?

It is intended for DIN-rail mounting and has an IP20 rating, so it should be installed within an appropriate control enclosure to ensure ingress protection.

Which standards govern its safety and environmental compliance?

It conforms to RoHS and meets UL 60947-5-1 and EN 60947-5-1 requirements for control-device performance.

How large is the unit for panel planning?

The relay occupies a slim profile of 17.5mm width and a Compact overall size of 90x17.5x90mm for dense cabinet layouts.

Note

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