Omron K8AK-PM Series Monitoring Relay, 3 Electrical Phases, SPDT Contact Configuration - K8AKPM1200240VAC

This monitoring relay is a critical device designed for continuous supervision of three-phase power supplies in industrial environments. With dimensions of 100 x 22.5 x 90 mm, it actively monitors various electrical anomalies such as overvoltages, undervoltages, phase loss, and phase sequence. This product is ideal for safeguarding essential equipment against common electrical faults.

Features & Benefits

• Monitors overvoltages and undervoltages using separate relays
• Detects phase loss and phase sequence issues for improved reliability
• Configurable for either 3-phase 3-wire or 4-wire power supplies
• LED indicators show output status clearly for easy monitoring
• High operating temperature range of -20°C to +60°C for diverse usage

Applications

• Used in industrial facilities for reliable power supply monitoring
• Effective in electric motor to detect phase loss
• Utilised in automation systems to prevent equipment damage
• Suitable for installations requiring DIN rail mounting for space efficiency

How does this device ensure protection against electrical faults?

The dual SPDT relays facilitate distinct detection of overvoltages and undervoltages, thereby providing a reliable mechanism for safeguarding against electrical faults and potential damage to connected equipment.

Can I use this monitoring relay for different voltage levels?

Yes, the product accommodates various input voltage settings through DIP switch configurations, allowing it to function effectively with different voltage levels as per requirements.

What is the significance of having a phase sequence detection function?

The phase sequence detection function ensures the correct rotational direction of motors, preventing operational hazards and inefficiencies that could arise from incorrect phase connections.

How quickly can this relay react to voltage anomalies?

The relay can be set with a response time ranging from 0.1 seconds to 30 seconds, allowing for quick intervention, which can be essential in protecting sensitive electrical systems.
