PIO-16/16L(PM) can be connected the input signals to a device which can be current-driven, such as a switch or transistor output device.
The connection requires an external power supply to feed currents.
The PC card inputs the ON/OFF state of the current-driven device as a digital value.

The signal inputs are isolated by opto-couplers (ready to accept current sinking output signals). The PC card therefore requires an external power
supply to drive the inputs. The power requirement for each input pin is about 8 mA at 24 VDC (about 4 mA at 12 VDC).

When the switch is ON, the corresponding bit contains 1.
When the switch is OFF, by contrast, the bit contains 0.
