Specialized Concentrated Focused
Binary input signal can be connected with a photoelectric switch or a proximity switch of NPN (NO
or NC) type. Its joining method is as below.

Power Requirement
It is recommended to adopt DC24V/4.5A switch power for relays on the terminal board. If there
are a great many DC 24V relays controlled by binary output signal, users can appropriately expand the
power source capacity or add extra power (forcibly sharing ground with external power supply). Z-axis
brake and solenoid valve also need DC24V instead of external power to the greatest extent to reduce
the interference to CNC device by solenoid valve, etc.
