English Datasheet

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-PM1 Monitoring Relay.

• Resistant to inverter noise.

• Monitors over voltage, under voltage, phase sequence and loss for 3 and 4 wire power supplies.

• Switch setting.

• 2 x SPDT output relays.

• 5 A (resistive load) at 250 V ac

• Global power specification supported by one switchable unit.

• Output status monitored by using LED indicator.

K8AK-PM1 Model.

Monitoring Relay.

3-phase 3 wire mode, 200, 220, 230, 240 V ac.

3-phase 4 wire mode, 115, 127, 133, 138 V ac.

3-phase 3 or 4 wire input rages is switched using a DIP switch.

Power supply voltage is the same as the rated input value.

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
