MSB – Modbus sensor box

Signal converter (Voltage, Pt100 and Frequency) to RS485 with Modbus RTU protocol

Modbus Sensor Box is a sensor conditioning unit to convert (Volt, Pt100 e Hz) signals into RS485 over RTU Modbus protocol.

Modbus sensor box can receive signals from different sensors on the market as: solar irradiance sensor, also pyranometers (configurable sensitivity value), temperature sensors (Pt100), wind speed sensor (Hz) and Storm distance sensor.
