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.

Technical parameter
1) Supply voltage: 24VDC
2) Binary open-collector output
OC (open-collector) outputs drive capability with maximum allowable operating voltage 30VDC and
maximum allowable current 20mADC; so when the output terminal is active low, the maximum allowable
sucked current is 20mA.
