Instruction Sheet
1 WARNING
Please carefully read this instruction thoroughly prior to use the DVP04PT-H.
In order to prevent electric shock, do not touch the terminals or conduct any maintenance while
power to the PLC 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 was certified to meet the IEC 61131-2 (UL 508) safety
requirements when installed in an enclosure.
The DVP04PT-H 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-H.
Make sure that the DVP04PT-H is properly grounded , to prevent any electromagnetic noise.
Use wires with resistance when connect the platinum resistance thermister (RTD) to PLC.
Please keep the wires as short as possible when connecting the RTD to PLC, and keep power
wires as far away as possible from I/O wires to prevent noise interference.
2 INTRODUCTION
2.1 Model Explanation and Peripherals
 Thank you for choosing DELTA DVP PLC Series. 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 converts the sensors input into a 14 bit digital signal, and
then be manipulated by using TO and FROM instructions in the ladder logic program. There are
49 Controlled Registers (CR, each register has 16 bits) in each module.
 Software version DVP04PT-H platinum temperature sensors can be updated via RS-485
communication.
 DVP04PT-H displays both Centigrade and Fahrenheit. The input resolution for Centigrade is 0.1
degrees and for Fahrenheit is 0.18 degrees.

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

 The rules for adding multiple special modules to a Main Processing Unit:
 m1: The maximum number of special modules attached to an MPU is 8. The

 In ES series models, flag M1083 is not provided. When FROM/TO instruction is
executed, all interrupts (including external or internal interrupt subroutines) will be
disabled. All interrupts will be executed after FROM/TO instruction is completed.
Besides, FROM/TO instruction also can be executed in the interrupt subroutine.
 The function of the flag M1083 (FROM/TO mode exchange) provided in EP/EH
series models:
a. When M1083=Off, all interrupts (including external or internal interrupt
subroutines) will be disabled when FROM/TO instruction is executed. The
Interrupts will resumed after FROM/TO instruction complete. Please be
advised FROM/TO instruction can be executed in the interrupt subroutine.
b. When M1083=On, if an interrupt enable occurs while FROM/TO
instruction are executing, the interrupt FROM/TO instruction will be
blocked till the requested interrupt finish. Unlike M1080 off situation,
FROM/TO instruction cannot be executed in the interrupt subroutine.
