R4DCB08 8-channel DS18B20 to RS485 converter

Product detailed description

The R4DCB08 module is an 8-channel converter for DS18B20 temperature sensors to an industrial RS485 interface using the Modbus RTU protocol. It enables easy integration of up to 8 temperature sensors into industrial systems, PLCs, control units, or custom projects using Arduino or Raspberry Pi. Thanks to its wide power supply range and robust RS485 output, it is suitable for remote temperature monitoring in demanding operating conditions.
