Instruction Sheet
1 WARNING
Always read this manual thoroughly before using the DVP04DA-H.
The DC input power must be disconnected before any maintenance.
This is an OPEN-TYPE built-in DVP04DA-H, and the DVP04DA-H is certified to meet the safety
requirements of IEC 61131-2 (UL 508) when installed in the enclosure to avoid high temperature,
high humidity, exceessive vibration, corrosive gases, liquids, airbome dust or metallic particles.
Also, it is equipped with protective methods such as some special tool or key to open the
enclosure, so as to avoid the hazard to users and the damage to the DVP04DA-H.
Do not connect the AC power to any of the input/output terminals, as it might cause damage to
the DVP04DA-H. Make sure that all the wiring is well conducted prior to power on.
Do not touch the internal circuit for at least 1 minute after the power supply is disconnected.
Make sure that the DVP04DA-H is properly grounded , to avoid any electromagnetic noise.
2 INTRODUCTION
2.1 Model Explanation and Peripherals
 Thank you for choosing DELTA’s PLC DVP Series. The analog output module of DVP04DA-H
series can read/write the data of analog output module by using commands FROM / TO via
DVP-PLC EH Series MPU program. The analog output module receives 12-bit digital data of 4
groups from PLC MPU and transforms it into 4 points analog output signal (voltage or current).
 DVP04DA-H analog output module can update software version by RS-485 communication.
 Users can select output from voltage or current via wiring. Voltage output range is 0V ~ +10V DC
(resolution is 2.5 mV). Current output range is 0mA ~ 20mA (resolution is 5 µA).

LSB (Least Significant Bit): 1. Voltage output: 1LSB=10V/8000=2.5mV. 2. Current output: 1LSB=20mA/4000=5µA.
Explanation:
1. The content of CR#0 is model type, user can read the data from program to know if there is expansion
module.
2. CR#1 is used to set two inner channels working mode of analog output module. Every channel has
four modes to set and can be set individually. For example: if setting CH1 to mode 2 (b2~b0=010),
CH2 to mode 1(b5~b3=001). It needs to set CR#1 to H000A. The factory setting of CR#1 is H0000.
3. CR#2 ~ CR#5, CR#10 ~ CR#17, CR#22, CR#23, CR#28, CR#29 Reserved.
4. CR #6 ~ CR#9 display CH1~CH4 output signal. The setting range is K0~K4000. Factory setting is K0
and unit is LSB.
5. CR#18 ~ CR#21 means the value of adjusting OFFSET value of CH1~CH4. The factory setting is K0
and unit is LSB. If output value equal to 0 after calculating, the adjustable range of analog output
voltage or current is -2000~+2000.
Voltage adjustable range: -5V~+5V(-2000LSB~+2000LSB).
Current adjustable range: -10mA~+10mA (-2000LSB~+2000LSB).
6. CR#24 ~ CR#27 means the value of adjust GAIN value of CH1~CH4. The factory setting is K2000 and
unit is LSB. If output value equal to 2000 after calculating, the adjustable range of analog output
voltage or current is -1600~+8000.
Voltage adjustable range: -4V~+20V(-1600LSB~+8000LSB).
Current adjustable range: -8mA ~+40mA (-1600LSB~+8000LSB).
But it needs to notice that GAIN VALUE – OFFSET VALUE = +400LSB ~+6000LSB (voltage or
current). When this value is under this range, the resolution of the output signal will be thin and the
variation of value will be larger. When this value exceeds this range, the resolution of output signal will
be thick and the variation of value will be smaller.
7. CR#30 is fault code. Please refer to the following chart.

8. CR#31 is used to set RS-485 communication address. The setting range is from 01 to 255. The factory
setting is K1.

9. CR#32 is used to set RS-485 communication baud rate: 4800, 9600, 19200, 38400, 57600, 115200
bps. b0: 4800bps. b1: 9600bps. (factory setting) b2: 19200bps. b3: 38400 bps. b4: 57600 bps. b5:
115200 bps. b6-b13: reserved. b14: exchange low and high byte of CRC check code. (only for RTU

1 stop bit (7 E 1). Communication format of RTU mode is 8Bit, even bit, 1 stop bit (8 E 1).
10. CR#33 is used to set the inner function priority. For example: characteristic register. Output latched
function will save output setting in the inner memory before power loss.
11. CR#34 is software version of model type.
12. CR#35~ CR#48 are used for system.
13. The corresponding parameters address H4032~H4063 of CR#0~CR#48 can provide user to
read/write data by RS-485.
