HUST CNC H2N - Output Signals

HUST H2N Connecting Manual
5 - 4
The input signal I007 is specially reserved for G31 skip function. All other 23 input
signals and 16 outputs are free for customer’s use.
• Input Signal Specification : The voltage to drive the input signal is 24V, but the
signal line is connected to the “sink” end (0V). The current is 8 mA.
• Input Signal Directly Connected to CNC (NPN-type)
Input signal bypasses the input board and is directly connected to P2 connector
on CNC.

5.4 Output Signals
Output signal is the one from CNC controller to an external device. The output
circuit of HUST H2N controller is a transistor circuit that can be used to drive a relay
or LED, etc.
