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.


The module connects to the router using Bluetooth® technology.
The module communicates with the router via Bluetooth® Low Energy. Communication of several hundred meters is also possible in Bluetooth® Long Range mode.

Various power supply options available depending on site conditions
Power supply to modules can be selected according to installation conditions and sensing frequency. Options include power from the router via module cable, from a BraveJIG Battery, from a distribution board or AC power source via an external power conversion adapter, or from a mobile battery using a Module USB Type-A conversion cable.
