DVP02DA-S Analog Output Module

Instruction Sheet

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.

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 Current adjustable range: -10mA~+10mA (-2000

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 Current adjustable range: -8mA ~+40mA (-1600

current). When 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.

7. CR#30 is the fault code. Please refer to the following chart.

Fault Description Power Source Abnormal Analog Input Value Error Setting Mode Error Offset/Gain Error Hardware Malfunction Digital Range Error Average Times Setting Error Command Error

Note: Each fault code will have corresponding bit (b0~b7). Two or more faults may happen at the same time. 0
