Omron K8AK-PW/PM/PH/PA Monitoring Relays

The Omron K8AK series monitoring relays are expertly designed for accurate and reliable monitoring for industrial facilities and equipment.
The K8AK-PW/PM monitoring relays are designed to bear greater resistance to inverter noise, suitable for monitoring 3-phase power supplies.
The K8AK-PH relays are ideal for preventing issues with motor operation and assisting phase loss detection.
The K8AK-PA relays are suitable for 3-phase voltage asymmetry monitoring.

K8AH-PA2 Monitoring Relay.

• Resistant to inverter noise.
• Monitor voltage asymmetry, phase sequence plus phase loss for three-phase 3-wire or 4-wire power supplies with one unit.
• Switch setting for 3-phase 3-wire or 3-phase 4-wire power supply.
• One SPDT output relay, 5 A ate 250 V ac (resistive load).
• Global power specification supported by one unit. (Switching)
• Relay status monitored by using LED indicator.

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
