Analog Input Module
Instruction Sheet
Warning
9
Please read this instruction carefully before use.
9
Switch off the power before wiring.
9
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.
9
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.
9
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.
9
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: 5
μ
A).

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.

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.
