| - | 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. | + | Extension xG18 communicates with the PLC using a two-wire RS-485 connection.
