DVP04PT-S Platinum Temperature Sensors
Instruction Sheet

WARNING
Please carefully read this instruction thoroughly prior to use the DVP04PT-S.
In order to prevent electric shock, do not touch the terminals or conduct any maintenance while
PLC power is ON.
DO NOT open the PLC. Only qualified personel or Delta staff is allowed to
conduct any internal electrical work on the PLC.
This is an OPEN-TYPE device and certified to meet IEC 61131-2 (UL 508) safety requirements
when installed in an enclosure.
The 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 the DVP04PT-S.
Make sure that the DVP04PT-S is properly grounded , to prevent any electromagnetic noise.
Use wires with resistance when connecting the platinum resistance thermister (RTD) to the PLC.
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
2.1 Model Explanation and Peripherals
Thank you for choosing DELTA DVP Series PLC. The DVP04PT-S allows the connection of four
platinum temperature sensors (PT100 3-WIRE 100Ω 3850 PPM/°C(DIN 43760 JIS C1604-1989)).
The PLC converts the sensors input to a 14-bit digital signal, which then be manipulated using TO
and FROM commands in the ladder logic program. There are 49 Controlled Registers (CR, each
register has 16-bit) in each module.
DVP04PT-S is able to share the information via RS-485 communication or by direct connect to
DVP-SS main processing unit. Power supply and main processing units are sold separately.
DVP04PT-S displays both Centigrade and Fahrenheit. The input resolution for Centigrade is 0.1
degrees and for Fahrenheit is 0.18 degrees.

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
