Please carefully read this instruction thoroughly prior to use the DVP02DA-S. The DC input power must be OFF before any maintenance. This is an OPEN-TYPE built-in DVP02DA-S, and the DVP02DA-S is certified to meet the safety requirements of
IEC 61131-2 (UL 508) 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, so as to avoid the hazard to users or any damage to the DVP02DA-S.
DO NOT connect the AC power to any of the input/output terminals, or it may the DVP02DA-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 DVP02DA-S is properly grounded , to avoid any electromagnetic noise.
Introduction
ENGLISH
 Model Explanation & Peripherals
 Thank you for choosing Delta DVP PLC Series. The analog output module of DVP02DA-S series can
read/write the data of analog output module by using instr uctions FROM/TO via DVP-PLC
SS/SA/SX/SC/SV Series MPU program. The analog output module receives 2 group 12-bit digital data
from PLC MPU and converts it into 2 points analog output signal (voltage or current). There are 49 CR
(Control Register) in each module and there are 16 bits in each register.
 The software version of DVP02DA-S analog o utput module can be updated via RS-485 comm unication.
Power unit and module are separate. Size is small and easy to install.
 Users can select output either voltage or current via wir ing. Voltage output range is 0V ~ +10V DC
(resolution is 2.5mV). Current output range is 0mA ~ 20mA (resolution is 5µA).
