English Datasheet

Omron K8AK-VS/VW Monitoring Relays

Manual resetting and automatically resetting supported by one relay
Pre-alarm monitoring mode
Compact housings
Resistant to high-frequency noise
Compliance with global power and safety standards

The Omron K8AK series monitoring relays are expertly designed for accurate and reliable monitoring of industrial facilities and equipment. The K8AK-VW/VS relays are ideal for monitoring overvoltages and undervoltages, which the K8AK-VW can do simultaneously.

What is a Monitoring / Measuring Relay?

A monitoring / measuring relay is a protective control device, various types are available suiting what you wish to monitor. The relays receive input signals then monitor them and then output an alarm signal when a set value is reached (alarm relays). The relays protect your equipment against over voltage and over current faults. Monitoring relays monitor AC power supplies, voltage and current, analogue signals detecting unusual activity in equipment against set alarm thresholds.

Types of Monitoring Relays Available?

• Motor protection relays
• Temperature monitoring relays
• Water level control relays
• Voltage
• Current
