Analog Output Module

Instruction Sheet

Warning

9 Please read this instruction carefully before use.

Switch off the power before wiring.

9

DVP04DA-H2 is an OPEN-TYPE device and therefore should be installed in an enclosure free of

9

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 damage on the device may occur.

DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may

9

occur. Check all the wiring again before switching on the power.

DO NOT tough any terminal when the power is switched on. DO NOT touch any internal circuit in 1

9

minute after the power is switched off.

Make sure the groud terminal is correctly grounded in order to prevent electromagnetic

9

interference.

 Introduction

1.1 Model Explanation & Peripherals

Thank you for choosing Delta DVP series. DVP04DA-H2 is able to read and write data of DVP04DA-H2 analog



signal output modules through FROM/TO instructions given by the program of DVP-EH2 series MPU. The
analog signal output module receives 4 groups of 12-bit digital data from PLC MPU and converts the data into 4
points of analog signals for output in either voltage or current.

 The user can select voltage or current output by wiring. Range of voltage output: 0V ~ +10VDC (resolution:

2.5mV). Range of current output: 0mA ~ 20mA (resolution: 5μA).

Note:

1. When performing analog output, please isolate other power wirings.

2. If the ripples at the loaded input terminal are too significant that causes noise interference on the wiring, connect the
wiring to 0.1 ~ 0.47μF 25V capacitor.

3. Please connect the

terminal on both the power modules and DVP04DA-H2 to the system earth point and ground the

system contact or connect it to the cover of power distribution cabinet.

4. DO NOT wire empty terminals

LSB

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 four channels in the analog input module. There are 4 modes for each channel
which can be set up separately. For example, if the user needs to set up CH1: mode 0 (b2 ~ b0 = 000); CH2:
mode 1 (b5 ~ b3 = 001), CH3: mode 2 (b8 ~ b6 = 010) and CH4: mode 3 (b11 ~ b9 = 011), CR#1 has to be set
as H’000A and the higher bits (b12 ~ b15) have to be reserved. Default value = H’0000.

3. CR#2 ~ CR#5, CR#10 ~ CR#17, CR#22, CR#23, CR#28 and CR#29 are reserved.

4. CR#6 ~ CR#9: The output values of CH1 ~ CH4 (range: K0 ~ K4,000; default = K0; unit: LSB)

5. CR#18 ~ CR#21: The adjusted OFFSET value of CH1 ~ CH4 (default = K0, unit = LSB), representing the analog

output voltage or current when the output digital value = 0 after calculation. The adjustable range: -2,000 ~

13. CR#0 ~ CR#34: The corresponding parameter addresses H’4032 ~ H’4054 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: 4,800/9,600/19,200/38,400/57,600/115,200bps

b. Modbus ASCII/RTU communication protocols: 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 to register); H’10 (write many word data to

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. After ERROR LED being on for 0.5
second, D/A 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 is higher than

19.5V.

3. When controlled by RS-485, the RS-485 LED will flash after receiving 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.
