Warning

 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.



 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 instructions 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 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 either voltage or current via wiring. Voltage output range is 0V ~ +10V DC

(resolution is 2.5mV). Current output range is 0mA ~ 20mA (resolution is 5µA).
