Warning
Please read this instruction carefully before use.
Switch off the power before wiring.
DVP04DA-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 damage on the device may occur.
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.
DO NOT tough any terminal when the power is switched on. DO NOT touch any internal circuit in 1
minute after the power is switched off.
Make sure the groud terminal is correctly grounded in order to prevent electromagnetic
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
system contact or connect it to the cover of power distribution cabinet.
4. DO NOT wire empty terminals

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 ~
+2,000.
The adjustable range of voltage: -5V ~ +5V (-2,000 ~ +2,000 )
LSB LSB
The adjustable range of current: -10mA ~ +10mA (-2,000 ~ +2,000
LSB
6. CR#24 ~ CR#2: The adjusted GAIN value of CH1 ~ CH4 (default = K2,000, unit = LSB), representing the analog
output voltage or current when the output digital value = 2,000 after calculation.
