Please read this instruction carefully before use. Switch off the power before wiring. DVP04AD-H2 is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust,
humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key or specific tools are required to open the enclosure) in case danger and damage on the device may occur.
DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check all
the wiring again before switching on the power.
DO NOT touch any terminal when the power is switched on. DO NOT touch any internal circuit in 1 minute after the
power is switched off.
Make sure the groud terminal is correctly grounded in order to prevent electromagnetic interference.
ENGLISH
Introduction
Model Explanation and Peripherals
Thank you for choosing Delta DVP series PLC. DVP04AD-H2 is able to receive 4 points of analog input
signals (voltage or current) and convert them into 14-bit digital signals. Besides, through FROM/TO
instructions in DVP-EH2 MPU program, the data in DVP04AD-H2 can be read or written. There are 49
16-bit control registers (CR) in DVP04AD-H2.
You can select voltage or current output by wiring. Range of voltage output: ±10V DC (resolution:
1.25mV). Range of current output: ±20mA (resolution: 5µA).

b3 = 001), CR#1 has to be set as H000A and the hi gher bits (b12 ~ b15) have to be reserved. Default val ue = H’0000.
