DC input signal A
DC input signal A is from the machine to the CNC, and they are from the press key at
the machie side, limit switch and contact of relay.

Contacts at the machine side should meet the following:
Contact capacity: over DC30V, 16mA.
Leak current between contacts during open circuit: below 1mA(voltage 26.4).
Voltage-drop between contacts during closed-circuit: below 2V(current 8.5mA,
including voltage-drop of cable).
