Omron K8AK-VW Series Monitoring Relay, 1 Electrical Phase, 2 x SPDT Contact Configuration - K8AK-VW3 24VAC/DC


This monitoring relay is designed for effective voltage supervision across electrical systems. With compact dimensions of 22.5mm x 100mm x 90mm, it efficiently monitors for overvoltages and undervoltages, ensuring reliable operation of sensitive equipment. Operating within a temperature range of -20°C to +60°C, it is well-suited for various industrial environments and applications.

Features & Benefits


• Supports simultaneous monitoring of overvoltages and undervoltages
• Separate settings for overvoltage and undervoltage outputs enhance flexibility
• SPDT contact configuration allows for versatile relay connections
• Inputs isolated from power supply enhance safety during operation
• LED indicators provide clear status updates on output performance

Applications


• Used in industrial facilities for voltage regulation
• Suitable for equipment needing consistent voltage monitoring
• Ideal for process control systems requiring precise voltage management
• Utilised in electrical panels for safeguarding against voltage fluctuations

What range of input voltages can be monitored with this device?


The relay can monitor input voltages across a range of 20 to 600 V AC/DC, depending on the selected terminal connections.

How does the time delay feature improve system reliability?


This feature allows for a configurable delay between detecting voltage issues and relay activation, preventing false alarms during transient conditions.

What are the implications of selecting manual versus automatic reset?


Manual reset requires the operator to intervene to reactivate after an alarm, while automatic reset re-engages the relay once conditions normalise, offering flexibility based on operational needs.
