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: 5μA).

Note:

1.When performing analog output, please isolate other power wirings.

2.If the ripples at the loaded input terminal are too significant that causes noise interference on the wiring, connect the wiring to 0.1 ~ 0.47μF 25V capacitor.

3.Please connect the terminal on both the power modules and DVP04DA-H2 to the system earth point and ground the system contact or connect it to the cover of power distribution cabinet.

4.DO NOT wire empty terminals

Protection

Communication mode (RS-485)

When connected to DVP-PLC MPU in series

Voltage output is protected by short circuit. Short circuit lasting for too long may cause damage on internal circuits. Current output can be open circuit.

ASCII/RTU mode.

Communication speed: 4,800/9,600/19,200/38,400/57,600/115,200 bps

ASCII data format: 7-bit, Even bit, 1 stop bit (7, E, 1)

RTU data format: 8-bit, Even bit, 1 stop bit (8, E, 1) RS-485 cannot be used when connected to PLC MPU.

The modules are numbered from 0 to 7 automatically by their distance from MPU. No.0 is the closest to MPU and No.7 is the furthest. Maximum 8 modules are allowed to connect to MPU and will not occupy any digital I/O points.

Symbols

○: latched (when written in through RS-485 communication)

╳: non-latched

R:Able to read data by FROM instruction or RS-485 communication

W:Able to write data by TO instruction or RS-485 communication

LSB (Least Significant Bit): For voltage output	1LSB = 10V/4,000 = 2.5mV。
For current output	1LSB = 20mA/4,000 = 5μA。

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:
