Omron K8DT-AW Series Monitoring Relay, 200A Maximum Current Sensed, 10A Minimum Current Sensed - K8DT-AW3TD
This monitoring relay provides single-phase current supervision for protection of electrical systems in industrial control panels. It senses deviations from set current thresholds and issues a transistor switching signal at 24V to indicate overcurrent or undercurrent conditions. Designed for DIN-rail mounting, it operates within typical industrial temperature ranges and connects via push-in terminals for Rapid installation.
Features and Benefits:
• Detects currents from 10 A to 200 A, offering a broad sensing range
• Adjustable time delay 0.1-30 s, reducing nuisance trips during transients
• Accepts 20.4-26.4V supply for flexible DC/AC control systems
• Transistor output enables fast solid-state signalling at 24 V
• Low power draw of 1.8 VA, minimising load on the control supply
• Adjustable time delay 0.1-30 s, reducing nuisance trips during transients
• Accepts 20.4-26.4V supply for flexible DC/AC control systems
• Transistor output enables fast solid-state signalling at 24 V
• Low power draw of 1.8 VA, minimising load on the control supply
Applications
• Suitable for monitoring motor running currents to indicate stall or overload
• Ideal for detecting supply loss on single-phase feeders in panels
• Used with industrial controllers to alarm on undervoltage-driven low current
• Can be used for preventive maintenance by logging persistent overcurrent events

What environmental protection does it provide for panel use?
The enclosure has an IP20 rating, offering protection against solid objects while requiring installation inside an enclosed cabinet.
How is it mounted and connected in existing switchgear?
It clips onto a standard DIN rail and uses push-in terminals to simplify wiring without screws.
What thermal limits should be observed during operation?
It is specified to operate between -20 °C and 60 °C, so ambient and adjacent component heating must be considered.
Which output configuration is available for interfacing with PLCs?
A transistor contact configuration is provided, suitable for direct interfacing with 24V control inputs.
Are there any material or regulatory considerations for procurement?
The unit complies with RoHS directives, indicating restriction of certain hazardous substances.
