Omron K8DT-AS Series Monitoring Relay, 5A Maximum Current Sensed, 17.5mm Width - K8DT-AS2CD

This monitoring relay provides overcurrent and undercurrent detection for single-phase electrical systems, designed for DIN-rail mounting in industrial control panels. It monitors load current between 0.1-5A and operates an SPDT contact when thresholds are exceeded or not met, offering a Compact control solution for phase-related protection and routine monitoring tasks.

Features and Benefits:

• 0.1-5A sensing range prevents equipment damage from abnormal currents • 20.4-26.4V AC/DC supply enables flexible supply options • SPDT contact supports both make and break control logic • 250 MS time delay avoids nuisance trips during transient events • Push-in terminals reduce wiring time and improve connection security • 1.8 VA power draw minimises auxiliary supply loading

Applications

• Suitable for monitoring motor load current in starter panels • Ideal for phase-failure protection in single-phase distribution • Used for supervision of pumps and fans to detect underload • Can be used for input monitoring on automation racks with DIN-rail • Used with control circuits requiring Compact relay modules

What environmental conditions can it operate within?

It is rated to operate between -20 °C and 60 °C, suitable for typical industrial indoor environments.

How is the relay mounted and how much panel space does it occupy?

It clips onto a standard DIN rail and occupies a 17.5mm width, allowing dense installation in control cabinets.

What contact currents can the relay switch?

The output contacts are rated for switching currents of 0.1 A for low-level signals and up to 5A for control circuits.

Which standards does the device comply with for safety and materials?

It conforms to RoHS and meets the electrical performance criteria of UL 60947-5-1 and EN 60947-5-1.

What ingress protection does the enclosure provide?

The unit has an IP20 rating, offering Basic protection against touch and larger foreign objects in a cabinet environment.

Note

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