WARNING
Always read this instruction thoroughly before using the DVP04AD-S.
The DC input power must be disconnected before any maintenance.
This is an OPEN-TYPE built-in DVP04AD-S, and the DVP04AD-S is certified to meet the safety
requirements of IEC 61131-2 (UL 508) when installed in the enclosure to avoid 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, so as to avoid the hazard to users and the damage to the DVP04AD-S.
Do not connect the AC power to any of the input/output terminals, as it might cause damage to
the DVP04AD-S. 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 disconnected.
Make sure that the DVP04AD-S is properly grounded
, to avoid any electromagnetic noise.

INTRODUCTION
2.1 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 transforms it into 14 bits digital signal. The
analog input module of DVP04AD-S series can read/write the data of analog input module by
using commands FROM / TO via DVP-PLC SS/SA/SX Series MPU program. There are 49
CR(Control Register) in each module and there are 16 bits in each register.
DVP04AD-S analog input module can update software version by RS-485 communication. Power
unit and module are separate. Small volume and easy to install.
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 expansion module.
2.
CR#1: CR#1 is used to set 4 inner 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
