English Datasheet

Omron K8DT-AS Series Monitoring Relay, 10A Relay Contact Current, 250ms Time Delay - K8DT-AS3TD

This monitoring relay detects and responds to deviations in current so single‑phase installations maintain defined operating conditions. It is designed for rail mounting in control cabinets and provides timed switching to protect equipment against both low and high current events while operating across a wide ambient temperature range.

Features and Benefits:

• Detects current from 10A to 200A, ensuring adjustable sensing coverage
• Provides undercurrent and overcurrent detection to prevent fault conditions
• Implements a 250 MS time delay to avoid nuisance switching
• Uses push‑in terminals for fast, tool‑free wiring
• Employs SPST contact configuration for straightforward control integration
• Consumes 1.8 VA, ensuring low auxiliary power draw during operation

Applications

• Suitable for motor protection circuits where current limits must be monitored
• Ideal for monitoring branch circuits in industrial automation panels
• Used with single‑phase distribution systems for load supervision
• Can be used for preventative maintenance alarms on critical equipment

What environmental range can I expect during installation and operation?

It operates between -20 °C and 60 °C, so it is suitable for many indoor industrial environments but not for outdoor exposure beyond its enclosure rating.

How is it mounted within a control cabinet?

The unit is intended for DIN‑rail mounting, enabling quick installation alongside other modular control devices.

What protection rating does the enclosure provide against ingress?

The device has an IP20 rating, which protects against finger contact but not against liquids or fine dust ingress.

What standards does the product meet for electrical control use?

It conforms to EN 60947‑5‑1 and UL 60947‑5‑1 and is RoHS‑compliant, aligning with recognised control relay requirements.

What are the switching capability limits of the relay contact?

The relay contact is rated for switching currents including a nominal 10A and a maximum sensed current of 200A for detection purposes.

Note

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