Omron K8AK-AS/AW Monitoring Relays
The Omron K8AK series monitoring relays are expertly designed for accurate and reliable monitoring for industrial facilities and equipment. The K8AK-AW/AS relays are suitable for undercurrent and overcurrent monitoring, which the K8AK-AW can do simultaneously.
Manual resetting and automatically resetting can be maintained by one relay.
Startup lock and operating time can be set individually.
Manual resetting and automatically resetting can be maintained by one relay.
Startup lock and operating time can be set individually.

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.
