GLD4100 Locating Leakage Controller

Description

KEY FEATURES
– Leak Detection: The module detects liquid leaks and indicates the location of the leak.
– Relay Functionality: It switches a relay to provide local voltage-free contact closure upon leak detection.
– Versatile Use: Can function as a standalone leak detection alarm or communicate with host monitoring systems (e.g., PLC) using standard RS-485 protocols.
– Cost-Effective Solution: Its affordability allows for the creation of robust systems with multiple independent sensing cable segments.
– No Calibration Needed: The GLD4100 does not require field calibration, simplifying installation and maintenance.

DESIGN FEATURES
– Voltage-Free Contacts: For alarm signaling.
– LED Indicators: Show power, leak detection, cable issues, and communication status.
– LCD Display: Indicates specific leak locations.
– RS-485 Communication: Twisted pair connection up to 1200 meters (4000 feet) with automatic protocol selection (MODBUS, Opto 22, Metasys).
– Power Supply Options: Supports 24, 120, or 230 Vac (50/60 Hz) and 12/24 Vdc.
– Unique Addressing: Assigns a unique address via software—no physical switches needed.
– Relay Configuration: Software-selectable for normally energized or de-energized modes.
– DIN Rail Mountable: Simplifies installation.
– Selectable Units: Choose between feet or meters.
