Sort Terminal Name Function Description
Analog
input
AI1-GND
Analog input
terminal 1
1. Input voltage range: DC0 ~10V
2. Input impedance: 100KΩ
AI2-GND
Analog input
terminal 2
1. Input range: DC0~10V/4~20mA, determined
by the CL3 DIP switch on the control board, the
factory is voltage mode.
2. Input impedance: 100kΩ for voltage input,
500Ω for current input.
Digital
input
DI1-COM Digital input 1
1. Optical coupling isolation, compatible with
bipolar input, switch by DI DIP switch, the factory
is NPN mode
2. Input impedance: 3.3k Ω
3. Voltage range for level input: 9~30V
4. HDI5 can be used as high-speed input port,
the maximum input frequency is 50KHz
5. DI6~DI10 are expansion board interfaces.
DI2-COM Digital input 2
DI3-COM Digital input 3
DI4-COM Digital input 4
DI5-COM Digital input 5
DI6-COM Digital input 6
DI7-COM Digital input 7
DI8-COM Digital input 8
DI9-COM Digital input 9
DI10-COM Digital input 10
Analog
output
AO1-GND Analog output 1
The voltage or current output is determined by
the DIP switch on the control board (refer to the
bit number of the terminal wiring diagram).
Output voltage range: 0 ~ 10V
Output current range: 0 ~ 20mA
AO2-GND Analog output 2
Digital
output
Y1-CAE Digital output 1
Optocoupler isolation, bipolar open collector
output
Output voltage range: 0 ~ 24V
Output current range: 0 ~ 50mA
Note: The digital output ground CAE and the
digital input ground COM are internally isolated,
but the CAE and COM have been externally
short-circuited before leaving the factory (in this
case, Y1 is driven by +24V by default). When Y1
wants to drive with an external power supply, the
external short connection between CAE and
COM must be disconnected.
