The Omron K8AK-VS3 100-240VAC is a compact single-phase voltage monitoring relay designed for industrial automation and control panel applications. With a slim 22.5 mm DIN rail mounting format, it helps monitor overvoltage or undervoltage conditions across AC or DC circuits, supporting voltage monitoring ranges from 20 to 600 V and a 100 to 240 V AC supply input.
This model features a relay output with SPDT contact configuration, making it suitable for signalling, interlocking and control functions where reliable voltage supervision is required. Screw terminals support secure panel wiring, while the compact black housing allows straightforward integration into space-conscious electrical enclosures.
Commonly used in machinery control systems, power distribution panels and equipment protection circuits, the K8AK-VS3 100-240VAC provides a practical solution for detecting abnormal voltage conditions and triggering a response before operational issues escalate.

What type of monitoring relay is this?
It is a single-phase voltage monitoring relay designed to detect overvoltage or undervoltage conditions in industrial control panels and equipment.
What voltage range can it monitor?
The relay is designed for voltage monitoring across a broad range, covering 20 to 600 V AC or DC depending on the selected measuring range.
What control supply voltage does it use?
The K8AK-VS3 100-240VAC uses a 100 to 240 V AC supply, making it suitable for many common industrial control cabinet power systems.
What output contact arrangement does it have?
It has one SPDT relay output contact, allowing it to switch a connected control circuit when the set voltage condition is detected.
How wide is the relay?
The unit is 22.5 mm wide, which helps save space when mounted alongside other control components in a panel.
How is it mounted?
It is designed for DIN rail installation, making it suitable for standard industrial enclosure and control panel layouts.
What kind of terminals does it use?
The relay uses screw terminals, providing a conventional wired connection method for industrial panel wiring.
Can it be used for both AC and DC voltage monitoring?
Yes. The monitored input range covers AC or DC voltage, while the unit itself is powered by a 100 to 240 V AC supply.
What applications is this type of relay commonly used for?
It is commonly used to monitor voltage fluctuations in control panels, machinery power feeds, backup power changeover circuits, and equipment where under-voltage or over-voltage detection is required.
Does it monitor three-phase systems?
No. This model is intended for single-phase voltage monitoring. For three-phase monitoring, a dedicated three-phase voltage relay from the same general product family would normally be selected.
- Monitoring single-phase AC or DC voltage levels in industrial control panels
- Detecting overvoltage conditions before connected equipment is affected
- Detecting undervoltage conditions in power supply circuits
- Providing relay output signalling when voltage moves outside a set threshold
- Supervising control power for machinery, automation systems and panel equipment
- Triggering alarms or control actions during voltage fluctuation events
- Monitoring backup power, generator or battery-fed control circuits
- Supporting preventative maintenance by identifying abnormal supply voltage behaviour
- Protecting precision equipment from unstable incoming power conditions
- Integrating into DIN rail assemblies where compact 22.5 mm monitoring is required
