1 WARNING
Always read this manual thoroughly before using the DVP04PT-H.
In order to avoid electric shock, do not touch the terminals or conduct any maintenance while
power is applied to the PLC. Never open the PLC. Only qualified Delta personnel should conduct
any internal electrical work on the PLC.
This is an OPEN-TYPE device and is certified to meet the safety requirements of IEC 61131-2
(UL 508) when installed in an enclosure.
The DVP04PT-H must be placed in an 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, this will cause permanent damage to
the DVP04PT-H.
Make sure that the DVP04PT-H is properly grounded , to avoid 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 the RTD's to the PLC and keep
power wires as far away as possible from I/O wires to avoid noise interference.
2 INTRODUCTION
2.1 Model Explanation and Peripherals
Thank you for choosing DELTA's DVP Series PLC. The DVP04PT-H allows the connection of four
platinum temperature sensors (PT100 3-WIRE 100 Ω
C1604-1989)). The DVP-PLC EH MPU transforms the sensors input into a 14 bit digital signal,
which may then be manipulated using TO and FROM commands in the ladder logic program.
There are 49 Controlled Registers (CR) in each module (each register is 16 bits).
DVP04PT-H platinum temperature sensors can update software version by RS-485
communication.
The DVP04PT-H works with both Centigrade and Fahrenheit. The input resolution for Centigrade
is 0.1 degrees and for Fahrenheit is 0.18 degrees.

Upper bound and lower bound detection per channel
Yes, there are ASCII/RTU modes, communication rate can be
4800 /9600 /19200 /38400 /57600 /115200. Communication
format of ASCII mode is 7Bit, even bit, 1 stop bit (7 E 1).
Communication format of RTU mode is 8Bit, even bit, 1 stop bit (8

used. The RS-485 is disabled when the DVP04PT-H is connected
in series to an MPU (use the RS485 on MPU).
When DVP04PT-H modules are connected to an MPU, the
modules are numbered from 0 – 7. 0 is the closest to the MPU
and 7 is the furthest. The Maximum number of modules is 8
modules and they do not occupy any digital I/O points of the MPU.
