Wildcat (BL2000)
Figure 7(c). Example of Logic Gate Driving BL2000 Digital Input
The actual switching threshold is approximately 2.40 V for channels IN0–IN10. Anything
below this value is a logic 0, and anything above is a logic 1.
The A/D converter inputs can be used as additional digital inputs using the parameters
specified for the digIn software function call. The default threshold for channels IN11–
IN21 is also set to 2.40 V, but may be changed by adding two lines to your program as dis-
cussed for the digIn software function call.
The digital inputs are each fully protected over a range of -36 V to +36 V, and can handle
short spikes of ±40 V.
