Instruction Sheet
1 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.
2 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 100Ω3850 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.

 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, all interrupts (including external or internal interrupt
subroutines) will be disabled when FROM/TO command is executed. The
Interrupts will resumed after FROM/TO command complete. Please be advised
FROM/TO command can be executed in the interrupt subroutine.
2. When M1083=On, if an interrupt enable occurs while FROM/TO command are
executing, the interrupt FROM/TO command will be blocked till the requested
interrupt finish. Unlike M1080 off situation, FROM/TO command cannot be
executed in the interrupt subroutine.
