Информация за продукта "iSN-101/S3 Liquid Leak Detection Module, 1-ch with Modbus RTU and DCON"
The iSN-101/S3 CR is a compact liquid leak detection module that switches its own relay output when water is detected, so it can drive alarms or control equipment without an additional conversion module. Its single channel suits point detection with a probe or line detection with a sense cable.
The module can monitor sense cables of up to 500 meters, including the liquid leak detection cable and extended cables. Sensitivity is adjustable by rotary switch across a range of 26 KΩ ~ 580 KΩ. A buzzer sounds on detection and can be silenced with the push button, while two LEDs show power and alarm status.
Communication is over one RS-485 port using Modbus RTU or DCON, with software-configured baud rates from 1200 to 115200 bps. This allows the module to be integrated with networked collection hosts and monitoring systems for remote alarm and device control.
Applications
- Water pipe leak monitoring in buildings, including water, fire and sewage pipes
- Real-time leak detection in computer room base stations, warehouses, libraries, museums and industrial sites
- Monitoring air handling equipment, refrigeration units, liquid containers and pump tanks
- Detection in domestic water, drainage and electrical equipment areas
