Digital Inputs

The FB2100 flow computer with I/O option 2 includes two channels that you can
individually configure as digital inputs (DI), digital outputs (DO), or pulse inputs (PI).
When configured as digital inputs, the channels have the following characteristics:

can configure one, both, or
neither as AOs. Note: If you
configure both as AOs we
recommend you provide

Characteristics
 AO sinks current to system
ground
 Factory calibrated (re-
calibration is unnecessary for
at least 3 years)
 You can configure a fail state
so that on power up or if the
CPU fails the output drives to
0 µA
 When a channel is configured
as an AO it cannot be used as
an AI
