Please carefully read this instruction thoroughly prior to use the DVP04AD-H.
The DC input power must be OFF before any maintenance.
This is an OPEN-TYPE built-in DVP04AD-H, and the DVP04AD-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 the damage to the DVP04AD-H.
Do not connect the AC power to any of the input/output terminals, or it may damage the
DVP04AD-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 OFF.
Make sure that the DVP04AD-H is properly grounded
, to prevent any electromagnetic noise.

INTRODUCTION
Model Explanation and Peripherals
Thank you for choosing DELTA’s PLC DVP Series. The analog input module receives external
4-point analog signal input (voltage or current) and converts it into 14 bits digital signal. The
analog input module of DVP04AD-H series can read/write the data of analog input module by
using instructions FROM / TO via DVP-PLC EH Series MPU program. There are 49 CR (Control
Register, each register has 16-bit) in each module.
Software version of DVP04AD-H analog input module can be updated via RS-485 communication.
Users can select input from voltage or current via wiring. Voltage input range is
±10V
DC
(resolution is 1.25 mV). Current input range is
±20
mA (resolution is 5 µA).

Explanation:
1. CR#0: 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: CR#1 is used to set 4 internal channels working mode of analog input module. Every
channel has four modes to set and can be set individually. For example: if setting CH1 to mode 0
(b2~b0=000), CH2 to mode 1(b5~b3=001), CH3: mode2 (b8~b6=010), CH4: mode
3(b11~b9=011). It needs to set CR#1 to H0688 and the upper bit (b12~b15) will reserved. The
factory setting of CR#1 is H0000.
3. CR#2 ~ CR#5: it is used to set average times of CH1~CH4. Setting range is K1~K4096 and
factory setting is K10.
4. CR#6 to CR#9 are the average value that calculates according to the value that is set in
CR#2~CR#5 (average time of CH1~CH4 input signal). For example, if CR#2 (the average times
of CH1) is 10, it will calculate the average of CH1 input signal every 10 times.
5. CR#10, CR#11, CR#16, CR#17, CR#22, CR#23, CR#28, CR#29 reserved.
6. CR#12 ~ CR#15: display present value of CH1~CH4 input signal.
7. CR #18~ CR #21: the content is the value of adjusting OFFSET value of CH1~CH4 if analog
input voltage or current is 0 after it transfers from analog to digital. Voltage setting range:
-5V~+5V(-4000
LSB
~+4000
LSB
). Current setting range: -20mA~+20mA (-4000
LSB
~+4000

).
8. CR #24~ CR #27: means analog input voltage or current when conversion value from analog
signal to digital is 4000. Voltage setting range: -4V~+20V(-3200
LSB
~+16000

range: -16mA~+52mA(-3200

will be smaller.
