1 WARNING

Always read this manual thoroughly before using the DVP04DA-H.

The DC input power must be disconnected before any maintenance.

This is an OPEN-TYPE built-in DVP04DA-H, and the DVP04DA-H is certified to meet the safety

requirements of IEC 61131-2 (UL 508) when installed in the enclosure to avoid 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 and the damage to the DVP04DA-H.

Do not connect the AC power to any of the input/output terminals, as it might cause damage to

the DVP04DA-H. 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 supply is disconnected.

Make sure that the DVP04DA-H is properly grounded , to avoid any electromagnetic noise.

2 INTRODUCTION

2.1 Model Explanation and Peripherals

 Thank you for choosing DELTA’s PLC DVP Series. The analog output module of DVP04DA-H

series can read/write the data of analog output module by using commands FROM / TO via

DVP-PLC EH Series MPU program. The analog output module receives 12-bit digital data of 4

groups from PLC MPU and transforms it into 4 points analog output signal (voltage or current).

 DVP04DA-H analog output module can update software version by RS-485 communication.

 Users can select output from 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).
