Binary inputs of the B1 board (16 Binary input)
The digital inputs can be used to obtain information from the power system, for
example, the state of circuit breakers and other elements.
There are two options of binary input/output boards:
B1: 16 binary inputs and;
B2: 6 binary inputs (and 8 dry contact outputs)
All the binary inputs are optoisolated.
Note that, on the six-input slot, the first three inputs (terminals 17, 18 and 19 (of each
module have a common negative indicated as '-' (terminal 20). On the 16-input board,
BIs 09 to 12 (terminals 17 to 20) have a common negative and 13 to 16 (terminals 22 to
25) have another common negative.
