Instruction Sheet
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 Ω3850 PPM/°C (DIN 43760 JIS
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.

Command
Explanation
 : the module number you are probing. : the number of Controlled

 In ES series models, flag M1083 is not provided. When FROM/TO command is
executed, all interrupts (including external or internal interrupt subroutines) will be
disabled. All interrupts will be executed after FROM/TO command is completed.
Besides, FROM/TO command also can be executed in the interrupt subroutine.
 The function of the flag M1083 (FROM/TO mode exchange) provided in EP/EH
series models:
1. When M1083=Off, FROM/TO command is executed, all interrupts (including
external or internal interrupt subroutines) will be disabled. All interrupts will be
executed after FROM/TO command is completed. Besides, FROM/TO
command also can be executed in the interrupt subroutine.
2. When M1083=On, if an interrupt occurs while FROM/TO command has been
programmed, FROM/TO command will be interruptted to execute the interrupt.
However, FROM/TO command cannot be executed in the interrupt subroutine.
