Instruction Sheet

1 WARNING

Please carefully read this instruction thoroughly prior to use the DVP04DA-S. The DC input power must be OFF before any maintenance. This is an OPEN-TYPE built-in DVP04DA-S, and the DVP04DA-S is certified to meet IEC

61131-2 (UL 508) safety requirements 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, in order to prevent the hazard to users or any damage to the DVP04DA-S.

Do not connect the AC power to any of the input/output terminals, or it may damage the

DVP04DA-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 the DVP04DA-S is properly grounded to prevent any electromagnetic noise.

2 INTRODUCTION

2.1 Model Explanation and Peripherals

 Thank you for choosing DELTA DVP PLC Series. The analog output module of DVP04DA-S series

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

SS/SA/SX MPU program. The analog output module receives 12-bit digital data of 4 groups from

PLC MPU and converts it into 4 points analog output signal either in voltage or in current.

 The Software version of DVP04DA-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 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).

1. When power is on, POWER LED will be lit and ERROR LED will be lit for 0.5 second.

2. It is normal that POWER LED should be lit and ERROR LED should turn off. When power supply is lower than 19.5V, ERROR LED will blink continuously till the power voltage is higher than 19.5V.

3. When it connects to PLC MPU in series, RUN LED on MPU will be lit and A/D LED or D/A LED should blink.

4. After receiving the first RS-485 command during controlling via RS-485, A/D LED or D/A LED should blink.

5. After converting, ERROR LED should blink if input or output exceeds the upper bound or below the lower bound.
