Omron K8DT-AS Series Monitoring Relay, 100 to 240V AC Supply Voltage, 5A Relay Contact Current - K8DT-AS1CA

This monitoring relay provides continuous current surveillance for single-phase systems, detecting both overcurrent and undercurrent conditions to support motor and equipment protection. It accepts universal AC supply voltages or a dedicated DC supply and is designed for DIN-rail mounting in control panels and switchgear.

Features and Benefits:

• Adjustable sensing range 2mA-500mA for precise detection
• Single-pole changeover contact rated 5A for load switching
• 250ms timing delay to prevent nuisance trips from transients
• Works from 100-240V AC or 24V DC supply for installation flexibility
• Push-in terminals for Faster wiring and secure connections
• Low power consumption 2.5VA to minimise auxiliary loading

Applications

• Suitable for protecting motors against phase-loss and stall conditions
• Ideal for integration into automated control panels on DIN rail
• Used for monitoring current in industrial pump assemblies
• Can be used for fault detection in conveyor drive systems
• Used with single-phase distribution circuits in machinery

What environmental temperatures can it operate within?

It is specified to function between -20°C and 60°C, enabling use in typical factory and plant environments.

How is the device mounted and connected in assemblies?

It clips onto a DIN rail and uses push-in terminals for direct conductor insertion without additional connectors.

What mechanical protection does the enclosure provide?

The unit has IP20 ingress protection, suitable for enclosed panels but not for direct exposure to liquids.

What standards approvals does it meet for electrical safety?

It complies with EN 60947-5-1 and UL 60947-5-1 and meets RoHS requirements.

How many electrical phases does it monitor and what contact configuration is provided?

It monitors a single electrical phase and provides an SPDT contact arrangement for signalling or control.

Note

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