10310/2/1 Earth Leakage Detector (ELD)

Overview: The 10310/2/1 module is an Earth Leakage Detector (ELD) designed for monitoring and detecting earth faults in 24 V DC systems. It features a manual self-test function and earth connection monitoring for ensuring system integrity and safety.

Features:

• Earth Leakage Detection: Capable of monitoring earth faults in 24 V DC, 48 V DC, 60 V DC, or 110 V DC systems.
• Earth Connection Monitoring: Offers continuous or intermittent monitoring of the earth connection.
• Self-Test Functionality: Can be manually activated or triggered via input signals (Rst24, Rst110).
• Reset Options: Supports manual resetting or high-level signal application to Rst24 or Rst110 inputs.
• Test Capability: Tests the module and earth connection using a 1.5 kOhm resistor or a resistor connected to the Earth2 pin.
• LED Indicator: Displays the selected connection frequency when operating in intermittent mode.
