1.2.3 Analog/ Digital Conversion Characteristics

1) Voltage input
Analog/digital conversion module allows external analog input to be converted to digital value and to be operated
in the CPU. On voltage input, input of –10 V leads to digital value of 0 and 10 V to 16000.
Input of 1.25 mV is equal to digital value of 1. Therefore, input less than 1.25 mV shouldn't be converted but
ignored.
2) Current input
On current input, input of -20 mA leads to digital value of 8000 and 20 mA to 16000. Input of 2.5 ㎂ is equal to
digital value of 1. Therefore, input less than 2.5㎂ shouldn't be converted but ignored.
