Informações de produto "iSN-101/S2 Liquid Leak Detection Module, 1-ch with Relay Output and RS-485"
The iSN-101/S2 CR is a standalone 1-channel liquid leak detector that switches its own relay output when liquid is detected, so it can drive local or remote alarms without an additional conversion module. Its RS-485 port supports Modbus RTU and DCON, allowing it to report status to a supervisory system or collection host on the network.
Sensing is handled by a double-core leader cable of up to 500 m, or by point probes at fixed risk locations. Sensitivity is set with a rotary switch across 26 KΩ to 580 KΩ, and the module also raises an audible alarm that can be silenced with a push button. Modbus RTU device addresses can be configured in hardware.
This variant is supplied with a 3 m liquid leak detection cable and a 3 m extended cable. The module is designed for wall mounting and operates from a 10 to 30 VDC supply across -25 to +75 °C.
Applications
- Water pipe leak monitoring in buildings
- Detection of leakage from fire pipes and sewage pipes
- Domestic water, drainage and electrical equipment monitoring
- Computer room base stations, warehouses, libraries and museums
- Air handling equipment, refrigeration units, liquid containers and pump tanks
