Digital Input
(DI)
0 to 2 as follows under I/O
option 2 only:

1 or 2 non-isolated channels
on CPU board (DI/DO/PI1 and
DI/DO/PI2). Two always
present; you can configure
one, both, or neither as DIs.

Circuit protection

30ms input filtering

Maximum input frequency of
10 Hz

Selectable current source of 66
µA or 2 mA

Either externally driven or
internally driven and pulled to
ground by dry contact
closures or open collector
devices

When a channel is configured
as a DI it cannot be used as a
DO or PI channel

3.4 Digital Outputs
The FB2100 flow computer with I/O option 1 includes a single digital output. The FB2100
flow computer with I/O option 2 includes two channels you can configure as digital
outputs (DO), digital inputs (DI) or pulse inputs (PI).
