Omron K8AK-LS Monitoring Relays

The Omron K8AK series monitoring relays are expertly designed for accurate and reliable monitoring for industrial facilities and equipment. The K8AK-LS monitoring relays are ideal for liquid level control monitoring and preventing the chattering of relay contacts that occurs with ripples. The relay is also suitable as a floatless switch and can be wired simply with ferrules.

K8AK-LS Series.

• Self-holding circuit with circuit processing not depending external wiring.
• Switch between water supply, discharge with DIP switch setting.
• Sensitivity adjustment of operating resistance – 10 k to 100 kΩ – applications to range of liquids.
• Prevents chattering. Relay contacts with ripples.
• Easy ferrule wiring.

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.
