Omron K8DT-AW Series Monitoring Relay, 20.4 to 26.4V Supply Voltage, 2 mA to 500 mA Relay Contact Current - K8DT-AW1TD
This monitoring relay provides single-phase current sensing to detect both undercurrent and overcurrent conditions in control panels and automation systems. It operates from either AC or DC supply within a narrow voltage window and mounts neatly on standard DIN-rail assemblies for integration into electrical enclosures.
Features and Benefits:
• Detects currents from 2 mA to 500 mA for precise monitoring capabilities
• SPST contact configuration for straightforward switching operations
• Push-in terminals enable Rapid wiring and serviceability
• 250 MS response time to distinguish transient events from faults
• Low power draw at 1.8 VA to minimise supply loading
• IP20 enclosure rating for protected internal-panel use
• SPST contact configuration for straightforward switching operations
• Push-in terminals enable Rapid wiring and serviceability
• 250 MS response time to distinguish transient events from faults
• Low power draw at 1.8 VA to minimise supply loading
• IP20 enclosure rating for protected internal-panel use
Applications
• Suitable for motor-run detection in industrial control cabinets
• Ideal for monitoring small loads in HVAC control systems
• Used with single-phase supply lines for preventive maintenance alerts
• Can be used for line-loss and leakage detection in process equipment

What voltage range is required to power the device?
It accepts supply voltages between 20.4 and 26.4V in either AC or DC form.
How are field connections MADE to the unit?
Wiring connects via push-in terminals that allow tool-free conductor insertion and secure retention.
What mounting provision does the product use?
It clips onto a DIN rail for Compact panel installation and straightforward removal.
What environmental temperatures can it withstand during operation?
The unit is rated to operate down to -20 °C and up to 60 °C.
Which electrical phase does it monitor and what contact currents are supported?
It monitors a single-phase circuit and supports relay contact currents of 2 mA and 500 mA.
Note
K8DT-AS allow use in either overcurrent or undercurrent mode.
K8DT-AW allow overcurrent and undercurrent monitoring simultaneously
