DVP04TC-S Thermocouple Sensors
Instruction Sheet
1 WARNING
Always read this instruction thoroughly before using the DVP04TC-S.
Make sure that power is OFF before wiring.
This is an OPEN TYPE PLC. The PLC should be kept in an enclosure away from airborne dust,
humidity, electric shock risk and vibration. Also, it is equipped with protective methods such as
some special tools or keys to open the enclosure, in order to prevent hazard to users or damage
the PLC.
Do NOT connect the AC main circuit power supply to any of the input/output terminals, or it may
damage the PLC. Check all the wiring prior to power up.
Do NOT touch internal circuit within 1 minute after power is OFF.
Make sure that the DVP04TC-S is properly grounded , to avoid any electromagnetic noise.
2 INTRODUCTION
2.1 Model Explanation and Peripherals
 Thank you for choosing DELTA’s DVP Series PLC. The DVP04TC-S allows the connection of
four thermocouple sensors (Type J/K). The DVP04TC-S series can read/write the data by using
instructions FROM / TO via DVP-PLC SS/SA/SX/SC MPU program. There are 49 CR (Control
Register) in each module and 16 bits for each register.
 DVP04TC-S thermocouple sensor can update software version by RS-485. Power supply and
main processing units are sold separately.
 The DVP04TC-S works with both Centigrade and Fahrenheit. The input resolution for
Centigrade is 0.1 degrees and for Fahrenheit is 0.18 degrees.

Explanation:
1. CR#0: The PLC model type.

2. CR#1: Used to set the working mode of four channels (CH1~CH4). There are 2 modes (J-type
and K-type) for each channel and can be set individually. For example, If you want to set
CH1~CH4 as following: CH1: mode 0 (b2~b0=000), CH2: mode 1(b5~b3=001), CH3: mode
0(b8~b6=000) and CH4: mode 1(b11~b9=001), you should set CR#1 to H0208. The higher
bits (b12~b15) will be reserved and the factory setting is H0000.
3. CR#2 ~ CR#5: Used to set the times of input readings for the average temperature calculation.
The available range is K1~K4096 and factory setting is K10. (Note: When PLC sets average
times via TO/DTO instructions, please use rising-edge/falling-edge detection instruction (such
as LDP and LDF) to get correct average times.)
4. CR#6 ~ CR#9: The average temperature (°C). The average temperature is calculated from
multiple temperature readings. Example: If CR#2 is 10, the temperature in CR#6 will be the
average of the last 10 readings in CH1.
5. CR#10 ~ CR#13: The average temperature (°F). The average temperature is calculated from
multiple temperature readings. Example: If CR#2 is 10, the temperature in CR#12 will be the
average of the last 10 readings in CH1.
6. CR#14 ~ CR#17: display present temperature (°C) of CH1~CH4 input signal.
7. CR#18, CR#23, CR#28, CR#29 are reserved.
8. CR#19 ~ CR#22: display present temperature (°F) of CH1~CH4 input signal.
9. CR#24 ~ CR#27: display offset value of channels CH1~CH4. The range is -1000~+1000 and
unit is 0.1 degrees C. The definition of OFFSET is Actual temperature = temperature
measured by DVP04TC-S – OFFSET value.
10. CR#30 is a fault code register. Refer to the following chart.

Note: Each fault code will have corresponding bit (b0~b7). Two or more faults may happen at the same time. 0
means normal and 1 means fault occurs.
11. CR#31: RS-485 communication address. Setting range is 01~255 and factory setting is K1.

In SS 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 SA
/
EH series
models:
1. When M1083=Off, 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.
2. When M1083=On, if an interrupt occurs while FROM/TO instruction has been
programmed, FROM/TO instruction will be interruptted to execute the
interrupt. However, FROM/TO instruction cannot be executed in the interrupt
subroutine.
