Omron K8DT-AW Series Monitoring Relay, 100 to 240V AC Supply Voltage, 250ms Time Delay - K8DT-AW1CA

This monitoring relay provides current-monitoring functions for single-phase control systems, detecting both overcurrent and undercurrent conditions while operating from a universal AC supply. It is intended for DIN-rail installations in industrial control panels where compact, low-power monitoring is required and offers Basic ingress protection suited to electrical cabinet environments.

Features and Benefits:

• SPDT contact offers single-switching output for control circuits
• 100-240V AC supply enables wide voltage compatibility
• 250 MS time delay prevents nuisance tripping from transients
• Push-in terminals deliver Rapid tool-free wiring and maintenance
• Detects currents from 2 mA up to 500 mA for sensitive monitoring
• Power consumption of 2.5 VA minimises load on auxiliary supplies

Applications

• Suitable for motor-protection circuits requiring low-current sensing
• Ideal for control panels that need DIN-rail mounted components
• Used for monitoring auxiliary circuits in automation racks
• Can be used for detecting supply loss or load-drop conditions

What environmental temperatures can it withstand during operation?

It operates across a range from -20°C to 60°C, allowing use in unheated enclosures and workshops.

How does the relay accommodate panel space constraints?

The unit has a narrow 17.5mm profile to reduce occupied rail length when multiple modules are installed.

What terminals are provided for field wiring and how do they behave?

Push-in terminals accept stranded or solid conductors and secure wiring without screw‑tightening for Faster installation.

What electrical phases and IP protection are relevant for installation planning?

The relay is intended for single-phase systems and carries an IP20 rating, so it requires enclosure protection from access and ingress.

Note

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