Omron K8AK-VS Series Monitoring Relay, 20 to 600V Voltage Sensing Range, 1 SPDT Contact Configuration - K8AK-VS3 100-240VAC


This monitoring relay facilitates precise voltage monitoring in industrial applications, designed specifically for single-phase electrical systems. The compact dimensions (22.5 x 100 x 95 mm) make it suitable for DIN rail mounting, ensuring efficient use of space in control panels. With the ability to monitor voltages from 20 to 600 V AC/DC, it serves as an essential protective device against voltage fluctuations.

Features & Benefits


• Supports voltage sensing between 20 to 600 V AC/DC for versatile usage
• SPDT output relay allows switching between normally open and closed configurations
• LED indicators provide clear output status for quick monitoring
• Operating time adjustable from 0.1 to 30 seconds for customised response
• Input frequency range of 40 to 500 Hz enables compatibility with various systems

Applications


• Utilised for electrical phase monitoring in industrial facilities
• Ideal for protecting equipment from overvoltage and undervoltage conditions
• Serves as an effective voltage monitoring device in automation processes
• Deployable in environments requiring robust and reliable voltage regulation

How does the relay respond to voltage fluctuations within the sensing range?


It activates based on preset thresholds for overvoltage and undervoltage, helping to prevent equipment damage. Users can set this through the operating value settings.

What maintenance procedures should be followed to ensure long-term reliability?


Regularly inspect the wiring and connections for signs of wear or damage, and check indicator lights to confirm proper operation.

In what scenarios would automatic resetting be preferable over manual resetting?


Automatic resetting is beneficial in scenarios where continuous operation is critical, as it allows for seamless recovery after a voltage event without manual intervention.

How can the output relay's switching configuration be adjusted?


The switching method can be modified via the DIP switch settings on the unit, allowing users to easily select between normally open and normally closed options.
