Instruction Sheet
Warning
9Please read this instruction sheet carefully before use.
9Switch off the power before wiring.
9DVP04TC-H2 is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust,
humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device
(e.g. key or specific tools are required to open the enclosure) in case danger and damages on the device may occur.
9DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check all
the wiring again before switching on the power.
9DO NOT touch any terminal when the power is switched on.
9Make sure the ground termnial is correctly grounded in order to prevent electromagnetic interference.
9Keep the wire as short as possible between RTD and PLC and the power wire as far away as possible from I/O wire to
prevent interference.
Introduction
1.1 Model Explanation & Peripherals
Thank you for choosing Delta’s DVP series. DVP04TC-H2 is able to receive 4 points of external thermocouple
temperature sensors (J-type, K-type, R-type, S-type, T-type) and convert them into 14-bit digital signals.
Besides, through FROM/TO instructions in DVP-EH2 MPU program, DVP04TC-H2 is able to read and write the
data in the module. There are 49 16-bit control registers (CR) in DVP04TC-H2.
The power unit and module of DVP04TC-H2 are separate, compact in size and easy to install.
DVP04TC-H2 displays temperatures in Celsius (resolution: 0.1°C) and Fahrenheit (resolution: 0.18°F).

R: Able to read data by FROM instruction or RS-485 communication

Explanations:
1. CR#0: Model name. The user can read the model name from the program and see if the extension module
exists.

2. CR#1: The working mode of the 4 channels in the sensors selected by the temperature measurement module.
There are 2 modes (J-type and K-type) for each channel which can be set up separately. For example, if the
user needs to set up CH1: mode 0 (b2 ~ b0 = 100); CH2: mode 1 (b5 ~ b3 = 001); CH3: mode 0 (b8 ~ b6 =
000) and CH4: mode 1 (b11 ~ b9 = 001), CR#1 has to be set as H0208 and the higher bits (b12 ~ b15) have
to be reserved. The default value = H’0000.
3. CR#2 ~ CR#5: The times to average the temperatures measured at CH1 ~ CH4. Range: K1 ~ K20. Default =
K10. Please note that when PLC MPU writes in the average time by TO/DTO instruction, please use the
rising/falling edge contact detection instructions (LDP/LDF…) in case you may not obtain the correct average
temperature.
4. CR#6 ~ CR#9: The average Celsius temperature measured at CH1 ~ CH4 obtained from the average time
settings in CR#2 ~ CR#5. For example, if the average time is set as 10, the content in CR#6 ~ CR#9 will be
the average of the most recent 10 temperature signals in Celsius at CH1 ~ CH4.
5. CR#10 ~ CR#13: The average Fahrenheit temperature measured at CH1 ~ CH4 obtained from the average
time settings in CR#2 ~ CR#5. For example, if the average time is set as 10, the content in CR#10 ~ CR#13
will be the average of the most recent 10 temperature signals in Fahrenheit at CH1 ~ CH4.
6. CR #14 ~ CR #17: Displaying the present temperature in Celsius at CH1 ~ CH4
7. CR#18, CR#23, CR#28 and CR#29 are reserved.
8. CR #19 ~ CR #22: Displaying the present temperature in Fahrenheit at CH1 ~ CH4
9. CR #24 ~ CR #27: The adjusted OFFSET value of CH1 ~ CH4. Range: -1,000 ~ +1,000. Unit: 0.1°C.
Temperature measured by the module – OFFSET value = Actual temperature displayed.

11. CR#31: The setting of RS-485 communication address. Range: 01 ~ 255. Default = K1.
12. CR#32: The setting of RS-485 communication speed. b0: 4,800bps; b1: 9,600bps (default); b2: 19,200bps; b3:
38,400bps; b4: 57,600bps; b5: 115,200bps; b6 ~ b13: reserved; b14: high/low bit exchange of CRC checksum
(only valid in RTU mode); b15: switching between ASCII mode and RTU mode.
13. CR#33: b0 ~ b11: For returning the CR settings to default settings.
b12 ~ b15: ERR LED definition. Default: b12 ~ b15 = 1111.
14. CR#34: Firmware version of the model.
15. CR#35 ~ CR#48: Parameters for system use.
16. CR#0 ~ CR#34: The corresponding parameter address H’4096 ~ H’40B8 are for users to read/write data by
RS-485 communication. When using RS-485, the user has to separate the module with MPU first.
a. Communication baud rate: 4,800/9,600/19,200/38,400/57,600/115,200 bps.
b. Modbus ASCII/RTU communication protocol: ASCII data format (7-bit, Even bit, 1 stop bit (7, E, 1));
RTU data format (8-bit, Even bit, 1 stop bit (8, E, 1)).
c. Function: H’03 (read register data); H’06 (write 1 word datum into register); H’10 (write many word data
into register).
d. Latched CR should be written by RS-485 communication to stay latched. CR will not be latched if written
by MPU through TO/DTO instruction.

Trial Operation & Troubleshooting
LED Display
1. When the module is powered for the first time, POWER LED will be on and ERROR LED will be on for
0.5 second. After this, A/D LED will start to flash.
2. When the power supply is normal, POWER LED will be on and ERROR LED should be off. When the
power supply is less than 19.5V, ERROR LED will keep being on until the power supply goes higher
than 19.5V.
3. When controlled by RS485, RS-485 LED on the module will flash after receiving the RS-485
instruction.
4. When the input or output value exceeds the upper bound or falls below the lower bound after
conversion, ERROR LED will flash.

M1083 for switching instruction modes in EH2 series models
1. When M1083 = Off, during the execution of FROM/TO instruction, all external or internal
interruption subroutines will be forbidden. The interruptions are allowed only after FROM/TO
instruction finishes its execution. FROM/TO instruction can also be used in an interruption
subroutine.
2. When M1083 = On and an interruption signal occurs during the execution of FROM/TO
instruction, the interruption will be processed first (with a 100us delay) and the execution of
FROM/TO will be stopped. After the interruption subroutine finishes its execution, the
program will jump to the next instructio of FROM/TO. FROM/TO cannot be used in an
interruption subroutine.
