Instruction Sheet

Warning

9 Please read this instruction sheet carefully before use.

9 Switch off the power before wiring.

9 DVP04TC-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.

9 DO 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.

9 DO NOT touch any terminal when the power is switched on.

9 Make sure the ground termnial

9 Keep 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.

is correctly grounded in order to prevent electromagnetic 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).

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 =

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

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.

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.

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
