Omron K8DT-AW Series Monitoring Relay, 20.4-26.4V Supply Voltage, 250ms Time Delay - K8DT-AW1CD


This monitoring relay is a Compact device designed to detect and respond to variations in current within single‑phase electrical systems. It monitors both undercurrent and overcurrent conditions and operates from low‑voltage AC or DC supplies, making it suitable for control panels and automation cabinets where space is limited.

Features and Benefits:


• Detects currents from 2 mA to 500 mA, giving precise sensing thresholds
• SPDT contact offers flexible switching for control circuits
• Push‑in terminals enable quick tool‑free wiring connections
• Time delay 250 MS provides short transient tolerance before action
• Accepts 20.4-26.4V AC/DC for versatile low‑voltage supply options
• IP20 protection allows safe indoor installation in enclosures

Applications


• Suitable for motor protection circuits requiring under/overcurrent detection
• Ideal for fault monitoring in factory automation control racks
• Used with single‑phase supply systems in electrical distribution panels
• Can be used for load surveillance in process control cabinets
• Used for current‑sensing interlocks in machinery safety systems

What mounting arrangement does this device use?


It clips onto a standard DIN rail for Rapid incorporation into modular control panels.

What environmental temperatures can it tolerate during operation?


It is rated to function down to -20 °C and up to 60 °C for typical indoor industrial environments.

How much power does it consume when energised?


The unit draws 1.8 VA, which keeps control‑circuit loading minimal.

What switching capacities are available from the output?


The relay contacts handle currents as low as 2 mA and up to 500 mA for signalling and control tasks.

Which standards does it conform to for electrical safety and interchangeability?


It meets recognised EN and UL standards and is manufactured to RoHS requirements.

Note

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