Remote Monitoring of Industrial Equipment via Current Measurement

This 2-channel module is designed for measuring current values output from industrial analog sensors and other devices that support the 4-20 mA standard.
Using its built-in A/D converter and shunt resistors, the module performs high-precision current measurements from analog sensors connected through the dedicated Y-terminals.
The measured data is transmitted as uplink data through the BraveJIG Router to host applications, enabling remote monitoring and data analysis of industrial equipment.
