Product Introduction
1-channel ModBus-RTU master interface is connected to our company's 485-type water temperature, water level, ammonia nitrogen ion concentration, pH, dissolved oxygen concentration, conductivity, water turbidity and other equipment by default, but it also supports custom combinations.
2-channel relay output, which can be linked to any signal acquisition channel for alarm or automatic control use.
1 RJ45 network port, which can upload monitoring data to a remote monitoring software platform.
It has 1 ModBus-RTU slave interface, which can be connected to the user's own monitoring host, PLC, configuration screen or configuration software.
Can be connected to 1 outdoor LED monochrome display, default dot matrix 96*48 (supports maximum dot matrix 1024*256).
Supports dual power supply from mains and solar (solar panel + battery), ensuring the equipment can work normally and continuously even in harsh conditions.
