Amphenol Advanced Sensors LET-Elite Alarm Module
Amphenol Advanced Sensors LET-Elite Alarm Module uses the standard MODBUS-RTU protocol with a 2-wire RS485 port. The host computer reading interval shall be ≥ 500ms (recommended 1s). Its default address is 01 and is configurable via PC commands or LEAK-Talk software. The Amphenol Advanced Sensors LET-Elite Alarm Module supports BACnet IP and Modbus RTU/TCP.
Features
- Typical applications include leak detection for data centers, communication rooms, air conditioning and refrigeration units, liquid storage tanks, pipelines, valves, pumps, and other equipment where liquid leakage monitoring is required
- The LET-Elite alarm module can detect the leakage of water, acid-base, oil, and other liquids
- It can also connect the sense cable up to 1500 meters
- When a liquid leakage is detected, the leakage position is displayed through the LCD screen, and the relay alarm signal is output
- The LET-Elite alarm module can operate as a standalone detection and alarm unit or as part of a network with other LET-Elite alarm modules
- Using a standard communication protocol, the module can communicate with a monitoring system or host computer to provide remote alarm notification, status monitoring, and remote equipment control
- The output of the alarm relay can select multiple linkage modes, and normal power on or normal power off operation modes LED displays the power supply, leakage, cable fault, and communication status; the LCD displays the location of leakage
- There are three power supply models: 12VDC to 24VDC, 24VAC, and 220 VAC
- Serial RS-485 communication up to 1200 meters, can be a centralized monitoring network
- The alarm module has a special address assigned by the software
- Convenient installation of DIN 35mm guide rail
- The LET-Elite alarm module can be configured with a PC based on Microsoft Windows®
- The alarm module comes with independent configuration software
