Omron K8DT-AS Series Monitoring Relay, 5A Maximum Current Sensed, 0.1A Minimum Current Sensed - K8DT-AS2TA

This monitoring relay detects and responds to abnormal single‑phase current conditions, providing protection against both overcurrent and undercurrent scenarios in industrial control systems. It is engineered for DIN‑rail installation and integrates with automation and electrical setups to monitor load continuity and trigger control circuits when measured current falls outside set thresholds.

Features and Benefits:

• Sensitivity range 0.1A to 5A providing precise current detection
• Single‑pole single‑throw contact offering straightforward switching action
• 250ms time delay preventing nuisance trips from short transients
• Push‑in terminals enabling Rapid tool‑free wiring connections
• Low power draw of 2.5VA reducing supply loading during operation
• IP20 enclosure suitable for standard protected electrical cabinets

Applications

• Suitable for motor load supervision to flag underload conditions
• Ideal for pump systems to detect dry‑run or overload situations
• Used with control panels to monitor branch circuit currents
• Can be used for conveyor systems to indicate stall or overload
• Suitable for factory automation where a Compact footprint is required

What mounting method does it require?

It clips onto a DIN rail for standard control‑cabinet installation and retention.

What electrical phase is monitored?

It monitors a single electrical phase for current surveillance tasks.

What Terminal type is provided for field wiring?

Push‑in terminals accept conductors for quick and secure connection without screws.

What environmental temperature range supports reliable operation?

It operates between −20°C and 60°C to cover common industrial ambient conditions.

Note

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