Omron K8DT-AS Series Monitoring Relay, 100 to 240V AC Supply Voltage, 2.5VA Power Consumption - K8DT-AS1TA

This monitoring relay is designed to detect and respond to deviations in AC current within single-phase installations, providing timed switching for protection and control in industrial automation environments. It operates from a wide AC supply range and mounts on DIN-rail systems for panel integration.

Features and Benefits:

• Detects overcurrent and undercurrent to protect circuits
• Senses currents from 2 mA to 500 mA for miniature monitoring
• SPST contact delivers straightforward on/off switching
• 250 MS time delay enables transient-tolerant response
• 2.5 VA power consumption minimises load on supply
• Push-in terminals allow fast tool-free wiring

Applications

• Suitable for motor load monitoring to flag abnormal draw
• Ideal for control panels in manufacturing automation systems
• Used with single-phase supplies in building services monitoring
• Can be used for preventive maintenance of electrical equipment

What supply voltage ranges will it accept?

It accepts AC supplies between 100-240V AC, accommodating common industrial and commercial mains.

How is the device mounted and connected in control cabinets?

It clips onto standard DIN rail and uses push-in terminals for Rapid conductor insertion and secure connection.

What environmental temperatures can it operate within?

The unit is rated to operate from -20 °C up to 60 °C for typical indoor panel conditions.

What approvals and standards does it meet for electrical safety and materials?

It complies with RoHS and meets EN 60947-5-1 and UL 60947-5-1 standards relevant to control-circuit devices.

What protection does the enclosure provide against ingress?

The enclosure meets IP20, offering Basic protection against solid objects in enclosed electrical panels.

Note

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