Industrial Bus (RS-485) connections
Connecting the 4-terminal block to the RJ45 jack
Connecting certain sensors
Connecting Pt100 sensors
Pt100 and Pt1000 sensors are usually connected using 3 wires
All three wires must have the same properties (diameter, …)
When connecting a Pt100 using two wires only, connect the third terminal locally
Addresses of Temp-485 sensors with Pt100 elements
When shipped, the configured sensor address is in the A..Z range and shown on the label.
Address on the RS-485 bus can be changed in the TCP setup mode, see the “Configuring
temperature sensors in TCP Setup” chapter.
