SKU: SenMod-RTU-3B

Modbus-IoT Transmitter Large


Wireless transmitter and receiver enabled to connect industrial equipment under ModBus and 4-20mA standard.

The device acts as a ModBus Master allowing it to communicate with the connected slave devices. It interacts with the NarrowBists IoT Platform, creating ModBus IP virtual devices with an address range of 1-255.

It is a portable and robust solution to obtain information from any industrial environment.

Enabled to connect ModBus equipment with defined Mapping (electrical energy meters, ultrasonic level sensors, input and output modules, among other industrial equipment)

Acts as ModBus Master, Supports up to 4 slaves per Transceiver, Creates Payload with register values

Supports external power supply or batteries

Configuration through the LPWAN network, periodic, data encryption and transmission based on events or in real time.
