Function Description
Power supply
+10V‑GND
External +10 V
power supply
The terminal is used to provide
+10 V power supply to an external
unit with the maximum output
current 10 mA.
Generally, it is used to power an
external potentiometer with
resistance ranging from 1 kΩ to 5
kΩ.
+24V‑COM
External +24 V
power supply
The terminal is used to provide
+24 V power supply to an external
unit. Generally, it is used to power
DI/DO terminals and external
sensors.
The maximum output current is
200 mA
[Note 1]
.
OP
Input terminal
for external
power supply
It is connected to +24V by default.
To use an external signal to drive
terminals DI1 to DI5, disconnect
OP from +24V and connect it to an
external power supply.
Analog input
AI1‑GND
Analog input
terminal 1
Input voltage range: –10 VDC to
+10 VDC
Input impedance: 22 kΩ
AI2‑GND
Analog input
terminal 2
The terminal supports voltage
input (default), current input, and
temperature input.
When used as voltage/current
input, the terminal supports 0 V to
10 V, ‑10 V to +10 V, or 0 mA to 20
mA with the resolution 12‑bit and
the correction accuracy 0.3%.
The input impedance is 22 kΩ for
voltage input and 500 Ω or 250 Ω
for current input, which is set by
S2 and S3 DIP switches
