Omron K8DS-PM Series Monitoring Relay, 200 to 480VAC Monitoring Voltage Range, 5A Contact Current - K8DS-PM2

This monitoring relay provides protection for three-phase systems by checking phase sequence and undervoltage conditions within industrial installations. It is designed for DIN-rail mounting and monitors a 3-phase supply across a broad voltage band to help prevent motor and equipment damage from incorrect phase order or low voltage.

Features and Benefits:

• Monitors 3-phase supply across 200–480 VAC range for wide compatibility
• Detects phase sequence and undervoltage to prevent motor damage
• Single-pole double-throw contact rated 5A for control-circuit switching
• Screw-terminal connections for secure, serviceable wiring
• Operates within −25 °C to 65 °C for varied plant environments
• Conforms to multiple safety standards for installation acceptance

Applications

• Suitable for motor phase-sequence protection installations
• Ideal for automation panels requiring undervoltage supervision
• Used with 3-phase distribution systems in manufacturing plants
• Can be used for control circuits that require SPDT switching on fault
• Suitable for retrofit into DIN-rail-mounted control cabinets

What mounting method is used for fitting into control panels?

It clips onto a DIN rail, allowing standard rail-mounted installation and simple replacement.

How does the unit Interface electrically with control systems?

It provides screw terminals for incoming supply and an SPDT switching contact handling up to 250V AC switching voltage.

What environmental limits must be observed during operation?

The device is rated to operate between −25 °C and 65 °C and has an IP20 ingress-protection rating.

Which approvals support installation in regulated systems?

It meets recognised standards including EN 60947-5-1, UL508 and CSA C22.2 No.14 among others.
