3.2 Digital I/O

3.2.1 Digital Inputs

The BL2000 has 11 digital inputs, IN0–IN10, 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 down by moving the surface-mounted jumper at JP6 as shown in Figure 7.
