8.1 Outline
Features
The KV-AN6 has both A/D and D/A conversion functions. The A/D conversion
function converts analog input to digital data and stores the converted data in the
KV-300 CPU; the D/A conversion function converts digital data stored in the KV-300
CPU to analog output data for output devices.
A/D converter
Converts analog input to 16-bit binary data (digital data). (The effective bits are the
12 bits starting from the most significant digit.)
Three input ranges can be selected with a slide switch: -10 to +10 V (voltage), -5 to
+5 V (voltage), and 0 to 20 mA (current).
Each KV-AN6 module has 4 input channels.
D/A converter
Converts 16-bit binary data (digital data) to analog output. (The effective bits are the
12 bits starting from the most significant digit.)
Three output ranges can be selected with a slide switch: -10 to +10 V (voltage), -5 to
+5 V (voltage), and 4 to 20 mA (current).
Each KV-AN6 module has two output channels.
Note: As shown below, 12 bits of the 16-bit binary data, starting from the most
significant digit, are effective.
