The XBIO16 adds 16 digital I/O points to your SPLat controller. It is easy to use, appearing simply as another 16 inputs and 16 outputs. You can use each point as one or the other. No explicit initialization is required.
As outputs the XBIO bidirectional I/O points use a solid state Darlington switches between the pin and ground (0V). The load (say a solenoid coil) has to be connected between the output pin and the positive supply voltage. The maximum allowable output current is up to 400mA steady state, 500mA peak. There are onboard catch diodes, so it is safe driving inductive, non-motor loads up to the rated current. For motors the locked rotor current must be within the output rating. See the documentation for more detail, including allowable output currents when multiple outputs are on at once.
As inputs the XBIO bidirectional I/O points provide industry standard NPN compatibility. Tying the input pin to ground (0V) registers as an On (True/logic 1) state. Leaving it open circuit or driving it to the positive supply voltage registers as an Off (False/logic 0). See the documentation for more detail.
