Omron K8DS-PU Series Monitoring Relay, 380 to 480V Supply AC Voltage, 200 to 480VAC Monitoring Voltage Range - K8DS-PU2

This monitoring relay provides phase-sequence verification and undervoltage supervision for three-phase electrical systems. Designed for installation on DIN-rail assemblies, it monitors supply conditions across a broad voltage band and issues a switched output when predefined thresholds or phase-order anomalies occur, supporting control and protection functions in industrial installations.

Features and Benefits:

• Monitors three-phase supply across 200-480 VAC for wide coverage
• Detects incorrect phase order and prevents motor rotation issues
• Responds to undervoltage events to protect downstream equipment
• Single-pole double-throw contact delivers 5A switching capacity
• Terminal screws enable secure conductor connection for durability

Applications

• Suitable for motor control panels requiring phase-sequence and undervoltage protection
• Ideal for industrial automation cabinets on DIN-rail systems
• Used for plant equipment where loss of phase or low voltage must be detected
• Can be used for preventative monitoring in electrical distribution panels

What supply voltage range is required for operation?

It operates from a supply AC voltage of 380-480V and monitors system voltages between 200 and 480 VAC for detection functions.

How is the relay mounted and wired in control panels?

The unit is designed for DIN-rail mounting and uses screw terminals for connecting phase conductors and control wiring.

What environmental limits apply during use?

The device is rated to function between -20 °C and 60 °C ambient temperature while installed in appropriately ventilated enclosures.

Which safety and conformity standards are applicable?

It conforms to multiple international standards including EN 60947-5-1, UL 508 recognition, CSA C22.2 No.14, CCC GB/T 14048.5, and provisions of the Korean Radio Waves Act.

What contact arrangement and protection rating does it have?

The relay provides an SPDT contact configuration with IP20 enclosure protection.
