Introduction

 

1.1  Model Explanation & Peripherals 
 
™

 

Thank you for choosing Delta DVP series. DVP04DA-H2 is able to read and write data of DVP04DA-H2 analog 

signal output modules through FROM/TO instructions given by the program of DVP-EH2 series MPU. The 
analog signal output module receives 4 groups of 12-bit digital data from PLC MPU and converts the data into 4 
points of analog signals for output in either voltage or current. 

™

 

The user can select voltage or current output by wiring. Range of voltage output: 0V ~ +10VDC (resolution: 

2.5mV). Range of current output: 0mA ~ 20mA (resolution: 5μA).

cause damage on internal circuits. Current output can be open circuit. 

Communication mode 
(RS-485) 

ASCII/RTU mode.

When connected to 
DVP-PLC MPU in series

authorization 

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. (except CR#31, CR#32)

exists.

which can be set up separately. For example, if the user needs to set up CH1: mode 0 (b2 ~ b0 = 000); CH2: 
mode 1 (b5 ~ b3 = 001), CH3: mode 2 (b8 ~ b6 = 010) and CH4: mode 3 (b11 ~ b9 = 011), CR#1 has to be set 
as H’000A and the higher bits (b12 ~ b15) have to be reserved. Default value = H’0000.
