3.2 Digital I/O
3.2.1 Digital Inputs
The BL4S100 has 12 digital inputs, IN0–IN11, each of which is protected over a range of
–36 V to +36 V. The inputs are factory-configured to be pulled up to +5 V, but they can
also be pulled up to +K or pulled down to 0 V by changing a jumper as shown in Figure 6.
Table 2 summarizes the jumper settings.
