1.Product Introduction
This product is a high-performance water leak detection device ROC-LDA-B801, which is suitable for use with two-core water leakage sensing cables, point sensors, and normally open dry contact devices (float control switches, optical probes with adapters, limit switches, etc.). The immersion monitoring device monitors sensing cables up to 500 meters long. Water leakage controllers are suitable for installation in conventional (non-hazardous) areas. The leakage controller has 2 small LED indicators (showing power and communication activity respectively) and SPDT type contact relays. The leakage controller can be used as an independent leak detection and alarm unit, or it can be used by networking the main control system (computer or control automation system) through simple shielded twisted pair RS-485 serial communication cabling.
