Wiring Reference
1. General input:
XPCIE1028 motion control card provides users with isolated general input signals,
which can be used for input signals of switches, sensors or other devices.
→ Wiring Note
⚫
The wiring principle of high-speed digital input IN (0-7) and low-speed digital input
IN (8-23) is shown in the figure above. The external signal source can be an
optocoupler, a key switch or a sensor, etc., all can be connected as long as the
requirements on output of electric level can be achieved.
