1-Wire communication

The article presents the method of connecting 1-Wire sensors (DS18B20) in the system. The diagrams include two-wire as well as three-wire connections.

1. Two-wire connection of 1-Wire temperature sensors to the Analog In/Out DIN module:


2. Mixed connection of 1-Wire temperature sensors to the Analog In/Out DIN module:


3. Connection of 1-Wire temperature sensors to the flush mounted module (e.g. I/O 2/2 FM):
