3.2.1 Digital Inputs

The BL2600 has 16 digital inputs, DIN16–DIN31, 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 DCIN, or pulled down to 0 V in banks by changing a jumper as
shown in Figure 7.
