Omron K8AK-AS Series Monitoring Relay, SPDT Contact Configuration, Current Monitoring Application - K8AK-AS1 24VAC/DC


This monitoring relay is designed for effective current monitoring in industrial environments. It protects electrical systems by detecting both overcurrent and undercurrent conditions, ensuring safe and efficient operation. With features tailored for automation and electrical applications, it is essential for maintaining system integrity and performance.

Features & Benefits


• Monitors both overcurrent and undercurrent conditions
• Supports manual and automatic reset for flexibility
• One SPDT output relay allows for versatile connections
• LED indicators facilitate quick status monitoring and alarm notifications
• Inputs are isolated from the power supply for enhanced safety
• Configurable startup lock and operating times provide greater control

Applications


• Monitors electrical equipment in industrial settings
• Provides effective overcurrent protection in mechanical systems
• Compatible with various commercially available current transformers
• Suitable for installations requiring DIN rail mount relays
• Ideal for current sensing in diverse automation

How does the startup lock feature work?


The startup lock can be set from 0 to 30 seconds, activating when the input reaches approximately 30% of the set value to prevent unintended operation.

Can I connect different types of current transformers?


Yes, while the preferred model is designed for specific transformers, it can also accept commercially available CTs within defined limits.

What is the recommended wiring method for connections?


For consistent performance, solid wires of up to 2.5mm² should be used, and ferrules with insulating sleeves are recommended for twisted wires.

How do I monitor the output status?


The output status can be monitored using the built-in LED indicators for relay operation and alarm conditions.

What is the maximum input current it can handle?


The relay can detect a maximum current of 500mA, depending on the specific settings and model used.
