Warning
Please read this instruction carefully before use.
Switch off the power before wiring.
DVP04AD-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 touch 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. DVP04AD-H2 is able to receive 4 points of analog input signals
(voltage or current) and convert them into 14-bit digital signals. Besides, through FROM/TO instructions in
DVP-EH2 MPU program, DVP04AD-H2 is able to read and write the data in the module. There are 49 16-bit
control registers (CR) in DVP04AD-H2.
The user can select voltage or current output by wiring. Range of voltage output: ±10VDC (resolution: 1.25mV).
Range of current output: ±20mA (resolution: 5μA).

*1. When performing analog input, 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.
NOTE: 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 two channels in the analog output 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 2 (b2 ~ b0 = 010) and CH2:
mode 1 (b5 ~ b3 = 001), CR#1 has to be set as H000A and the higher bits (b12 ~ b15) have to be reserved.
Default value = H'0000.

Default = H'0000. Take the setting of CH1 for example:
1. When b0 = 0, the user is allowed to tune CR#18 (OFFSET) and CR#24
(GAIN) of CH1. When b0 = 1, the user is not allowed to tune CR#18
(OFFSET) and CR#24 (GAIN) of CH1.
2. b1 represents whether the OFFSET/GAIN tuning registers are latched. b1
= 0 (default, latched); b1 = 1 (non-latched)
3. When b2 = 1, all settings will return to default values.
