WARNING
Please carefully read this instruction thoroughly prior to use the DVP02DA-S.
The DC input power must be OFF before any maintenance.
This is an OPEN-TYPE built-in DVP02DA-S, and the DVP02DA-S 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, so as to avoid the hazard to users or any damage to the DVP02DA-S.
Do not connect the AC power to any of the input/output terminals, or it may the DVP02DA-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 is Off.
Make sure that DVP02DA-S is properly grounded , to avoid any electromagnetic noise.

INTRODUCTION
2.1 Model Explanation and Peripherals
Thank you for choosing DELTA DVP PLC Series. The analog output module of DVP02DA-S series
can read/write the data of analog output module by using commands FROM / TO via DVP-PLC
SS/SA/SX Series MPU program. The analog output module receives 2 group 12-bit digital data
from PLC MPU and converts it into 2 points analog output signal (voltage or current). There are 49
CR (Control Register) in each module and there are 16 bits in each register.
The software version of DVP02DA-S analog output module can be updated via RS-485
communication. Power unit and module are separate. Size is small and easy to install.
Users can select output either voltage or current via wiring. Voltage output range is 0V ~ +10V DC
(resolution is 2.5 mV). Current output range is 0mA ~ 20mA (resolution is 5 µA).

Explanation:
1. The content of CR#0 is model type, user can read the data from program to check if there is
expansion module.
2. CR#1 is used to set two internal channels working mode of analog output module. Every channel
has four modes to set that can set individually. For example: if set CH1 to mode 2 (b2~b0=010),
CH2 to mode 1(b5~b3=001). It needs to set CR#1 to H000A. The factory setting of CR#1 is H0000.
3. CR#2 ~ CR#9, CR#12 ~ CR#21, CR#24 ~ CR#27 Reserved.
4. CR #10 ~ CR#11 display CH1 and CH2 output signal. The setting range is K0~K4000. Factory
setting is K0 and unit is LSB.
5. R#22 ~ CR#23 means the value to adjust OFFSET value of CH1 and CH2. The factory setting is K0
and unit is LSB. If output value equal to 0 after calculating, the adjustable range of analog output
voltage or current is -2000~+2000.
Voltage adjustable range: -5V~+5V(-2000
LSB
~+2000
LSB
).
Current adjustable range: -10mA~+10mA (-2000
LSB
~+2000
LSB
).
6. R#28 ~ CR#29 means the value of adjust GAIN value of CH1 and CH2. The factory setting is K2000
and unit is LSB. If output value equal to 2000 after calculating, the adjustable range of analog output
voltage or current is -1600~+8000.
Voltage adjustable range: -4V~+20V(-1600
LSB
~+8000

this value within this range, the resolution of the output signal will be thin and the
value variation will be larger. When this value exceeds this range, the resolution of output signal
will be thick and the variation of value will be smaller.
