This product is an industrial-grade three-channel AC current detection and protection module that supports real-time monitoring of three-channel AC current, upper and lower limit alarms, relay linkage output, and RS485 MODBUS RTU communication. It has three kinds of range : 0-50A,0-400A,0-1000A
The product uses a digital tube display and button menu configuration, making parameter settings simple and intuitive. It is suitable for various industrial automation scenarios, such as:
1.Conveyor belt stall protection
2.Fan overcurrent protection
3.Motor idle test
4.Feeder material breakage detection
5.Pump underload detection
6.Industrial equipment operation status monitoring
7.PLC Networked Monitoring System

Through this module ,it can highly protect the machine .
Here is the project case :
By the way, we also have PLC, rs485 relay module,Hmi, PLC ac amplifier boards, PLC dc amplifier board,PLC HMI all in one etc which can be suitable for many industry automation project. OEM &ODM is also acceptable.
