Instruction Sheet

Warning

9

Please read this instruction carefully before use.

9

Switch off the power before wiring.

9

DVP04DA-H2 is an OPEN-TYPE device and therefore should be installed in an enclosure free of
airborne dust, humidity, electric shock and vibration. The enclosure should prevent non-maintenance
staff from operating the device (e.g. key or specific tools are required to open the enclosure) in case
danger and damage on the device may occur.

9

DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may
occur. Check all the wiring again before switching on the power.

9

DO NOT tough any terminal when the power is switched on. DO NOT touch any internal circuit in 1
minute after the power is switched off.

9

Make sure the groud terminal

is correctly grounded in order to prevent electromagnetic

interference.

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: 5

μ

A).

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)

Explanations:

1.

CR#0: Model name. The user can read the model name from the program and see if the extension module

exists.

2.

CR#1: The working mode of the four channels in the analog input module. There are 4 modes for each channel

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.

3.

CR#2 ~ CR#5, CR#10 ~ CR#17, CR#22, CR#23, CR#28 and CR#29 are reserved.

4.

CR#6 ~ CR#9: The output values of CH1 ~ CH4 (range: K0 ~ K4,000; default = K0; unit: LSB)

5.

CR#18 ~ CR#21: The adjusted OFFSET value of CH1 ~ CH4 (default = K0, unit = LSB), representing the analog

output voltage or current when the output digital value = 0 after calculation. The adjustable range: -2,000 ~
+2,000.

The adjustable range of voltage: -5V ~ +5V (-2,000

LSB

~ +2,000

LSB

)

The adjustable range of current: -10mA ~ +10mA (-2,000

LSB

~ +2,000

LSB

)

6.

CR#24 ~ CR#2: The adjusted GAIN value of CH1 ~ CH4 (default = K2,000, unit = LSB), representing the analog

output voltage or current when the output digital value = 2,000 after calculation.
