GS-LDA-1
Water Leak Detection System
GS-LDA-1
Sensor Interface Module monitors up to 500 meters of GuardSen sensing cable (GS-LDC-1). When liquid is detected, the GS-LDA-1 unit indicates the leak with an LED and switches a relay to provide local voltage-free contact closure.
The GS-LDA-1 can be used as a standalone leak detection alarm unit or can also communicate to a host monitoring system such as PLC or Monitoring System by using standard RS-485 communications.
The low cost of the GS-LDA-1 makes it economical to build very robust systems with many small independent sensing cable segments. No field calibration is required.
DESIGN FEATURES
- LEDs to indicate power, leak, and communication status
- Voltage-free contacts for alarm signaling
- Standard twisted pair serial RS-485 communications up to 1200 meters (4000 feet) with Modbus protocol
- 12Vdc power supply
- Each GS-LDA-1 unit has a unique address assigned with software – no switches
- Built-in buzzer (85dB)
- DIN rail mounted for easy installation
- Sensor sensitivity adjustable
