*1: Wiring for analog input should adopt cables of PT100 / PT1000 temperature sensor or double shielded
cable and should be separated from other power cables that may cause interference. Please apply 3 wires
for PT100 / PT1000. If a 2 wires sensor is applied, please short-circuit I+ and I- terminals.
*2: Connect FE with
terminal for noise suppression.
*3: Connect the
terminal on both power module and DVP04PT-E2 to the system grounding point then
ground the point or connect it to the cover of power distribution cabinet.

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.
