 Are you looking for an affordable temperature measurement solution, need to read the temperature at longer distances, or want to automate a boiler room? Then the [[https://www.unipi.technology/unipi-extension-xg18-p331|Extension xG18]] is the ideal solution.
+This compact module is designed as a simple and reliable tool capable of reading temperature from up to 8 Unipi 1-Wire temperature sensors (DS18B20). Modbus RTU protocol on RS-485 serial line is used to provide the data to the control system.

-This compact module is designed as a simple and reliable tool capable of reading temperature from up to 8 Unipi 1-Wire temperature sensors (DS18B20). Modbus RTU protocol on RS-485 serial line is used to provide the data to the control system.
 Each 1-Wire channel is dedicated for just the one 1-Wire sensor with a RJ45 connector, which highly increases reliabily of the measurements.

 ===== 1 Connecting xG18 to an Unipi PLC =====
-Extension xG18 communicates with the PLC using a two-wire RS-485 connection. The module can be powered by the same power source as the PLC (if the power supply's specification allows it). Alternatively, you can use a standalone 5-24V DC power supply. As to temperature sensors, simply plug them into the available RJ45 ports.
