Terminal name Functional Description
Power supply
+10V-GND
External
conn 10v
power supply
External p 10v power supply the maximum output
current is 10mA, which is generally used as the working power
supply for external potentiometer and the resistance value of
potentiometer ranges will be from 2.5k ~ 5kΩ
+24V-COM
External
conn 24v
power supply
External p 24v power supply, generally used as working
power supply for digital input and output terminals and
maximum output current for external sensor power supply:
200mA
OP
External power
input terminal
24V or OP connection through the short connector 1
on the control panel, and the factory defaults to + 24v
connection. When X1 ~ X7 are driven by external signals, OP
needs to be connected to external power supply.
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/4mA~20mA
，
determined by the
selection of AI2 jumper on the control panel.
2. Input impedance: 22kΩ for voltage input and 500Ω for current
input.
AI3-GND
Analog input
terminal 3
1. Optical coupling isolation input can accept differential voltage
input, current input, temperature detection resistance input
2. Input range
：
DC 0V~10V
，
determined by the selection of AI3
jumper on the control panel.
Digital input
X1~X7 Digital input
1. Optical coupling isolation is compatible with bipolar input
2. Input impedance: 2.4kΩ
3. Voltage range during level input: 9V~30V
X5
High-speed pulse
input terminal
Besides the features of X1~X4, it can also be used as a
high-speed pulse input channel. Highest input frequency:
100kHz; Voltage range: 9V~30V
Analog output
AO1-GND Analog output 1
The AO1 jumper on the control board determines the voltage or
current output. Output voltage range: 0V ~ 10V output current
range: 0mA ~ 20mA
AO2-GND Analog output 2
The AO2 jumper on the control board determines the voltage or
current output. Output voltage range: 0V ~ 10V output current
range: 0mA ~ 20mA
Digital output
DO-CME Digital output 1
Optical coupling isolation, bipolar open collector output voltage
range: 0V ~ 24V output current range: 0mA ~ 20mA
Note: CME of digital output location is internally isolated from
com of digital input location, but at the factory it is shorted to
COM via short connector 2CME on the control board (DO1 is
driven by + 24v by default at this time). When DO1 is driven by
an external power supply, the short connector 2 must be
unplugged.
FM- COM
High speed pulse
output
Constrained by function code F4 - 00 " FM terminal output
mode selection" as high-speed pulse output, the highest
frequency is 100 kHz; When it is exported as open collector, it is
the same as DO1 specification.
