Description
GRI8-IW2 Current Monitor Relay Product Highlight：
Modular Range Coverage for Universal Compatibility
Pioneering modular architecture allows seamless range coverage from 0.15A to 15A by simply swapping front-end modules (E1/E2/E3). Three gear settings enable high-precision detection across the full range, significantly reducing equipment procurement costs and optimizing on-site adaptability.
True RMS Measurement for Superior Interference Resistance
Integrated True RMS algorithm accurately identifies non-sinusoidal currents in variable frequency drives and rectifier circuits. With ±5% high-precision standards, it effectively avoids false alarms caused by motor startup surges, ensuring exceptional performance in interference-heavy environments.
Dual-Core Independent Protection with Safety Redundancy
Dual SPDT relays operate independently, allowing separate threshold settings for overcurrent and undercurrent with flexible normally open/normally closed mode switching. Five-position DIP switches (SW1-SW5) lock logic settings to prevent accidental changes, ensuring robust and reliable protection strategies.
Triple Safety Protection Mechanism
Equipped with a conflict detection system that triggers an immediate alarm and interrupts output if the undercurrent threshold exceeds the overcurrent threshold. Capable of withstanding 120% continuous overload for harsh conditions and 150% instantaneous surges for 1 second to protect against sudden events like motor stalling.
Millisecond-Level Response for Industrial-Grade Protection
Adjustable delay range of 0.3s to 30s (±10% accuracy) perfectly aligns with motor thermal response curves. A fixed 5% hysteresis design minimizes equipment cycling due to current Fluctuations, enhancing overall lifespan.
Streamlined Maintenance and Diagnostic System
Multi-color LED array provides intuitive feedback: green for normal power supply, yellow for contact action status, and red for fault pinpointing. An innovative parameter persistence mechanism ensures DIP switch configurations remain intact after power loss, simplifying maintenance processes.
Application Areas
The GRI8-IW2 Current Monitor Relay is ideal for industrial motor protection, water pump system monitoring, heating equipment, and automation networks. It provides robust protection for manufacturing production lines and energy facilities.
