Omron K8DT-VS Series Monitoring Relay, 20.4-26.4V Supply Voltage, 10A Contact Current - K8DT-VS3TD

This monitoring relay is designed to detect and respond to voltage deviations within control and automation systems, providing protection against both excessive and insufficient supply levels. It is intended for single-phase installations and mounts on DIN rails for straightforward integration into control panels and switchgear.

Features and Benefits:

• Supply tolerance 20.4-26.4V supports stable operation
• Single-pole single-throw contact rated for 10 A enables robust switching
• Low power draw of 1.8 VA reduces panel power burden
• Push-in terminals permit fast, secure wiring without tools
• IP20 enclosure allows indoor cabinet installation
• Ambient operation from -20 to 60 °C suits varied plant environments

Applications

• Suitable for voltage monitoring on motor control panels
• Ideal for protection of automation PLC power supplies
• Used with single-phase distribution feeders in machinery
• Can be used for monitoring auxiliary control circuits in manufacturing

What contact arrangement does it use and what does that mean for wiring?

It uses a single-pole single-throw contact, so one switching circuit is controlled and wiring is simplified for single-load or control-signal interruption.

How does the unit mount in a control cabinet?

It is designed for DIN-rail mounting, enabling Rapid installation and alignment with other rail-mounted devices.

What approvals support its use in industrial installations?

The device meets UL 60947-5-1 and EN 60947-5-1 standards and is RoHS compliant, indicating conformity with recognised electrical safety and material-restriction criteria.

What environmental range can I expect in continuous service?

It is rated to operate reliably between -20 and 60 °C, covering typical indoor industrial ambient conditions.

How Compact is the device for dense panel layouts?

The relay has a narrow 17.5mm width, allowing high-density mounting in control panels.
