Terminal description of control circuit
Standard RS485 communication interface, using twisted pair or
shielded wire.
External + 10V power supply, maximum output current: 20mA.
Generally used for external potentiometer speed regulation.
Provide + 24V power supply for terminal, maximum output
current: 100 mA
It is generally used as working power supply for digital input and
output terminals.
External load is not allowed to connect.
Common terminal
of input X
When using the internal power supply to drive the X terminal:
COM and 24V are short circuited to form NPN input;
COM and 0V are short circuited to form PNP input;
When using the external 24V power supply to drive the X
terminal:
COM is connected to external power supply 24V+, disconnected
from 24V of VH6 to form NPN input;
COM is connected to external power supply 0V, disconnected
from 0V of VH6 to form PNP input;
Select voltage /current input by DIP switch
Input voltage range: 0~10V (Input impedance: 22kΩ)
Input current range: 0~20mA (Input impedance: 500Ω)
Select voltage/current output by DIP switch
Voltage output range: 0~10V. External load: 2kΩ-1MΩ
Current output range: 0~20mA. External load less than 500Ω
Optocoupler isolation input
Input impedance: R = 3.3KΩ
The input voltage range is 9 ~ 30V
Compatible with bipolar input
In addition to the characteristics of X1-X3, it can also be used
as a high-speed pulse input channel. The highest frequency is 50
kHz
Collector open circuit output
Output voltage range: 0 ~ 24V
