Tuotetiedot "iSN-101/S/DIN Liquid Leak Detection Module, 1-ch, Modbus RTU and DCON"
The iSN-101/S/DIN CR is a 1-channel liquid leak detector that switches its own relay when water is sensed, so it can drive a local alarm or signal a remote system without an additional converter. It is designed for point detection with a probe or line detection with a sense cable, and it suits monitoring in buildings, plant rooms and equipment areas where early warning of water ingress matters.
Sensitivity is set on a rotary switch across 26 KΩ to 580 KΩ, and the module provides an audible buzzer that can be silenced with a front push button. Its single SPST Form A relay makes the alarm state available to building management, PLCs or other collection hosts. Leak detection cable runs of up to 500 metres are supported, including the extended cables, and cable-break detection is available when used with the CA-LLD-DC100X-Lxxx sense cable.
For networked monitoring, the module communicates over one RS-485 port using Modbus RTU or DCON, with software-configured baud rates from 1200 to 115200 bps. This DIN-rail variant is supplied with a 1m liquid leak detection cable and a 3m extended cable, and it operates from a 10 to 30 VDC supply.
Applications
- Water pipe leak monitoring in buildings
- Monitoring of water, fire and sewage pipes
- Detection of leaks around domestic water, drainage and electric equipment
- Real-time leak detection in computer rooms, warehouses, libraries and museums
- Monitoring of air handling equipment, refrigeration units, liquid containers and pump tanks
