Honeywell 10310/1/1 Earth Leakage Detector

The Honeywell 10310/1/1 Earth Leakage Detector (ELD) efficiently monitors earth leakage in 24 VDC systems. It includes essential features like a manually operated self-test and an earth connection monitor. Additionally, it supports 48 VDC and 60 VDC supplies with a common 0 V rail, making it highly adaptable for various industrial needs.

Key Features of the Honeywell 10310/1/1 Earth Leakage Detector

Self-Test Capability: The ELD has an easy-to-activate self-test feature, ensuring constant system reliability.
Earth Fault Monitoring: It continuously monitors earth voltage and detects any fault thresholds, providing real-time alerts when leakage occurs.
Multiple Connection Modes: The module allows selection between continuous or interrupting modes, ensuring flexibility across applications.
Fault Location: By using the 1/4 Hz mode, the module enables accurate fault location with a current clamp and voltmeter.
LED Indicators: When in interrupting mode, the green “MODE” LED flashes to indicate the active frequency, simplifying monitoring.

Applications of the Honeywell 10310/1/1

Industrial Automation: This ELD is perfect for systems requiring constant monitoring of earth leakage in 24 VDC and 48 VDC control setups.
Power Supply Monitoring: It detects earth faults in power supplies, helping prevent equipment damage and maintaining safety.
Fault Detection: The module immediately identifies and locates earth faults, ensuring system integrity and avoiding operational risks.
