3 Platinum resistance temperature detector (RTD) sensor connection method
3.1 Connection terminal
After screwing the platinum resistance temperature detector into the temperature sensor connector,
insert it into the connector of the front panel. The terminal names of the input connectors are indicated
on the right side of the panel as A, B, and b.
+ /A terminal
Connect the A side wire of the platinum resistance temperature detector (RTD).
- /B terminal
Connect the B side wire of the platinum resistance temperature detector (RTD).
S /b terminal
Connect the b side wire of the platinum resistance temperature detector (RTD).
NOTE
Make sure to use a three-wire type platinum resistance temperature detector (RTD) sensor.
Use three equal length cables for RTD extension in order to match the resistance values.
Ensure the wire resistance is 10 Ω or less (per wire)
Connect a single RTD to a single channel.
Wire the RTD cable away from the power line and sources of noise.

4 Sensor cable connection
Step 1. Peel the coating of the sensor cable, and connect the cable to the socket.
0.2 sq to 1.5 sq (AWG 24 to AWG 16) wire is supported.
Insert the sensor cable from the right direction and tighten the top screw.
Gently pull the cable and confirm that it does not become disconnected.
