Analog
input
AI1-GND
Analog input
terminal 1
1
、
Input voltage range:DC 0V~10V
2
、
Input impedance :22kΩ
AI2-GND
Analog input
terminal 2
1
、
Input range: DC 0V ~10V /0mA ~20mA, decided
by the AI2 jumper on the control board.
2
、
Input impedance: 22 kΩ (voltage input), 500 Ω
(current input)
Digital
input

Digital input1
1
、
Optical coupling isolation, compatible with dual
polarity input
2
、
Impedance: 2.4 kΩ
3
、
Voltage range for level input: 9–30 V
X2-COM
Digital input2
X3-COM
Digital input3
X4-COM
Digital input4
X5-COM
High-speed pulse
input terminal
Besides features of X1
–
X4, it can be used for
high-speed pulse input.
Maximum input frequency: 100 kHz
Analog
output
AO1-GND
Analog output 1
Voltage or current output is decided by jumper AO1.
Output voltage range: 0–10 V
Output current range: 0–20 mA
AO2-GND
Analog output 2
Output range:0V~10V/0mA~20mA
Using the AO2 jumper on the left side of the control
board to determine the voltage or current output.
Digital
output
Y1-YCM
Digital output 1
Optical coupling isolation, dual polarity open
collector output
Output voltage range: 0–24 V
Output current range: 0–50 mA
Note that YCM and COM are internally insulated,
but they are shorted by jumper externally.
Y2-YCM
High-speed pulse
output terminal
It is limited by F3.00
As high-speed pulse output, the maximum frequency
hits 100 kHz.
As open-collector output, it specification is the same
as that of Y1
