Datasheet

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.

K8AK-AW Series.

• Monitors over and under currents
• Use available current transformers (CT)
• One relay supports manual and automatic resetting
• Start-up lock and operating time can be set separately
• Two SPDT output contacts. 5 A at 250 V ac resistive load
• Output relay can switch between normally open and closed
• LED indicator can be used to monitor output status
• Inputs are isolated from the power supply

K8AK-AW Models Available.

• K8AS-AW1 24 VAC/DC – Stock number 8193226

• K8AK-AW1 100-240 VAC - Stock number 8193223

• K8AK-AW2 24 VAC/DC - Stock number 8193239 (if using other current transformers do not exceed the overload capacity)

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.
