Instruction Sheet
1 WARNING
Please carefully read this instruction thoroughly prior to use the DVP04DA-H.
The DC input power must be OFF 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 prevent 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, in order to prevent the hazard to users and damage DVP04DA-H.
Do not connect the AC power to any of the input/output terminals, or it may 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 OFF.
Make sure that the DVP04DA-H is properly grounded , to prevent 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 instructions 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 converts it into 4 points analog output signal either in voltage or in
current.
 Software version of DVP04DA-H analog output module can be updated via RS-485.
 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 extension
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).
Please be noticed that GAIN VALUE – OFFSET VALUE = +400LSB ~+6000LSB (voltage or current). If the
value difference comes up small (within range), the output signal resolution is then slim and the
variation is definitely larger. On the contrast, if the value difference exceeds the range, the output
signal resolution becomes larger and the variation is definitely 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

series models:
1. When M1083=Off, all interrupts (including external or internal interrupt
subroutines) will be disabled when FROM/TO instruction is executed. The
Interrupts will resumed after FROM/TO instruction complete. Please be
advised FROM/TO instruction can be executed in the interrupt subroutine.
2. When M1083=On, if an interrupt enable occurs while FROM/TO instruction
are executing, the interrupt FROM/TO instruction will be blocked till the
requested interrupt finish. Unlike M1080 off situation, FROM/TO instruction
cannot be executed in the interrupt subroutine.
