DVP04AD-S Delta S Series PLC Analog I/O Module AI4 new in box


1. 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. 

2. 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.

3. 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 5uA).

Communication mode


Modbus ASCII/RTU Mode. Communication baud rate of 4,800/9,600/19,200/ 38,400/57,600/115,200. For ASCII mode, date format is 7 bits, even, 1 stop bit (7, E, 1), while RTU mode, date format is 8 bits, even, 1 stop bit (8, E, 1). The RS-485 is disabled when the DVP04AD-S is connected in series with MPU.

Connect to DVP-PLC MPU

in series

If DVP04AD-S modules are connected to MPU, the modules are numbered from 0 - 7. 0 is the closest and 7 is the furthest to the MPU. 8 modules is the max and they do not occupy any digital I/O points of the MPU.
