Delta Electronics Platinum Temperature Sensors DVP04PT-S Instruction Sheet

Warning

Please read this instruction sheet carefully before use.
In order to prevent electric shock, DO NOT touch the terminals or conduct any maintenance while the power is on.
DO NOT open the PLC. Only qualified personnel or Delta staff is allowed to conduct any internal electrical work
on the PLC.
DVP04PT-S is an OPEN-TYPE device and certified to meet IEC 61131-2 (UL 508) safety requirements when
installed in an enclosure.
DVP04PT-S must be kept under the environment away from high temperatures, high humidity, exceessive vibration,
corrosive gases, liquids, airborne dust, and metallic particles.
DO NOT apply AC power to any of the input/output terminals, or it may damage DVP04PT-S.
Make sure that the DVP04PT-S is properly grounded , to prevent any electromagnetic noise.
Please keep the wires as short as possible when connecting RTD to PLC and keep power lead as far away as
possible from I/O wires to prevent noise interference.

Introduction

Model Explanation & Peripherals
Thank you for choosing Delta DVP series PLC. DVP04PT-S is able to receive 4 points of platinum
temperature sensors (PT 100 3-WIRE 100 3850 PPM/°C (DIN 43760 JIS C1604-1989)) and convert
them into 14-bit digital signals. Besides, through FROM/TO instructions in DVP Slim series MPU program,
the data in DVP04PT-S can be read and written. There are 49 16-bit control registers (CR) in
DVP04PT-S.
The system version of DVP04PT-S can be updated via RS-485 communication. The power unit is
separate from it and is small in size and easy to install.
DVP04PT-S displays temperatures in both Celsius (resolution: 0.1° C) and Fahrenheit (resolution:
0.18° C).

Note 1: Use only the wires that are packed with the temperature sensor (PT 100) for analog input and separate from other
power line or any wire that may cause noise. Please use 3-wire for PT 100.
Note 2: Terminal FG is grounded for noise suppression.
Note 3: Please connect power supply module terminal and DVP-04PT-S temperature measurement module
terminal to system earth ground.
Warning: DO NOT connect wires to the No Connection terminals.
