Product Introduction
The GLD4100 Locating Leakage Detector can monitor the leakage situation in the environment in real time. It can quickly detect the specific location of the leakage. Once the leakage is detected, the controller will issue an alarm and display the leakage information on the LCD panel of the controller. It can also transmit the leakage information through the RS485 communication interface. At the same time, it will activate a relay to output the switch signal. This leakage controller has been programmed according to the MODBUS-RTU protocol, which is convenient for integration with the monitoring system and can monitor up to 500 meters of the sensing cable.











Product Parameters
The power supply of the GLD4100 Locating Liquid Leakage Controller is 12-24VDC wide voltage supply. It has one relay output. It can be connected to RS485 (MODBUS-RTU protocol). It can monitor the leakage detection cable up to 500 meters. Once the leakage is detected, its response time is less than 3 seconds. It is installed in a 35mm rail mounting method, and can be flexibly installed in the cabinet.
Product Certification
The GLD4100 Locating Liquid Leak Controller has obtained certifications such as CE, ROHS, FCC, and those from the metrology institute.
