7) I/O converstion characteristics
(1) Analog input characteristics
a) Voltage input
4000
2000
0
0V
In voltage input, digital amount 0 is output by 0V input and 4,000 is output by 10V input. Therefore input 2.5mV equals to
digital amount 1, but value less than 2.5mV can' t be converted.
b) Current input
4000
2000
0
0
Current input 0mA becomes output 0, 10mA does 2000 and 20mA does 4000. therefore input 5
1, but value less tan 5
