Functioning
The module continuously measures temperatures using external sensors. Readout of registered temperature values, setting of all measurement, communication and data exchange parameters are carried out through the RS-485 port using the Modbus RTU communication protocol. The switching on of the supply voltage is indicated by the green U LED.
The correct data exchange between the module and the other device is indicated by the yellow Tx LED.
The module works with the following 3-wire digital sensors:
DS1820, DS18B20, DS18S20.
Dedicated temperature probe made by F&F: RT-4 probe.
The probe is sold separately.
