Note1: Use only the wires that are packed with the temperature sensor for analog input and
separate from other power line or any wire that may cause noise.
Note2: Terminal FG is grounded for noise suppression.
Note3: Please connect
power supply module terminal and DVP04PT-S temperature
measurement module terminal to system earth ground.
Warning: DO NOT connect wires to the No Connection terminals.

Series connection to
DVP-PLC MPU
The modules are numbered from 0 to 7 automatically by their distance
from MPU. No.0 is the closest to MPU and No.7 is the furthest.
Maximum 8 modules are allowed to connect to MPU and will not
occupy any digital I/O points.
