Warning
Please carefully read this instruction sheet before use.
The DC input power must be OFF before any maintenance.
This is an OPEN-TYPE built-in DVP04AD-S, and the DVP04AD-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
DVP04AD-S.
DO NOT connect the AC power to any of the input/output terminals, or it may damage to the DVP04AD-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 supply is OFF.
Make sure that the DVP04AD-S is properly grounded , to prevent any electromagnetic noise.
Introduction
Model Explanation & Peripherals
Thank you for choosing DELTA PLC DVP Series. The analog input module receives external 4-point
analog signal input (voltage or current) and converts it into 14 bits digital signal. The analog input module
of DVP04AD-S series can read/write the data of analog input module by using instructions FROM/TO via
DVP-PLC SS/SA/SX/SC/SV Series MPU program. There are 49 CR (Control Register, each register has
16-bit) in each module.
The software version of DVP04AD-S analog input module can be updated via RS-485 communication.
Power unit and module are separate. Size is small and easy to install.
Users can select input from voltage or current via wiring. Voltage input range is ±10VDC (resolution is
1.25mV). Current input range is ±20mA (resolution is 5µA).

Installation and Wiring
Mounting Arrangements and Wiring Notes
DIN Rail Installation
The DVP-PLC can be secured to a cabinet by using the
DIN rail that is 35mm high with a depth of 7.5mm. When
mounting the PLC on the DIN rail, be sure to use the end
bracket to stop any side-to-side motion of the PLC, thus
to reduce the chance of the wires being pulled loose. On
the bottom of the PLC is a small retaining clip. To secure
the PLC to the DIN rail, place it onto the rail and gently
push up on the clip. To remove it, pull down on the
retaining clip and gently pull the PLC away from the DIN
rail. Please see the figure on the right:
For heat dissipation. Make
sure to provide a minimum
clearance of 50mm between
the unit and all sides of the
cabinet. (shown as below)
