This is an OPEN-TYPE built-in DVP04AD-H, and the DVP04AD-H 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, in order to prevent the hazard to users and the damage to the DVP04AD-H.

ꢀ Thank you for choosing DELTA’s 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-H series can read/write the data of analog input module by
using instructions FROM / TO via DVP-PLC EH Series MPU program. There are 49 CR (Control
Register, each register has 16-bit) in each module.

7. CR #18~ CR #21: the content is the value of adjusting OFFSET value of CH1~CH4 if analog
input voltage or current is 0 after it transfers from analog to digital. Voltage setting range:
-5V~+5V(-4000LSB~+4000LSB). Current setting range: -20mA~+20mA (-4000LSB~+4000LSB).
8. CR #24~ CR #27: means analog input voltage or current when conversion value from analog
signal to digital is 4000. Voltage setting range: -4V~+20V(-3200LSB~+16000LSB). Current setting
range: -16mA~+52mA(-3200LSB ~+10400LSB). But please be noticed GAIN VALUE – OFFSET
VALUE = +800LSB~+12000LSB (voltage) or +800LSB~+6400LSB (current). When this value under this
range, the resolution of the input signal will be thin and the variation of value will be larger. When
this value exceeds this range, the resolution of input signal will be thick and the variation of value
will be smaller.
