Analog
single-ended
input AI1
Receives analog voltage or
current single-ended input.
You can choose voltage or
current analog input
through the function code
P09.01 (reference ground:
GND).
Input voltage: 0 V to 10 V (input
impedance: 100 k
Ω
), resolution: 1/4000
Input current: 0 mA to 20 mA (input
impedance: 165
Ω
), resolution: 1/4000

Analog
single-ended
input AI2 or
analog current
differential
input AI2
Receives analog voltage or
current single-ended input,
or current differential input.
You can choose voltage or
current analog input
through the function code
P09.02 (reference ground:
GND).
Input voltage: -10 V to 10 V (input
impedance: 100 k
Ω
), resolution: 1/4000
Input current: 0 mA to 20 mA (input
impedance: 10

Differential
input current
return terminal
AI2_RE
Used as the current return
terminal during analog
current differential input. If
the analog current input is
single-ended, you need to
connect this terminal to
GND.
Input current: 0 mA to 20 mA (input
impedance: 10
Ω
), resolution: 1/4000,
supporting differential input
