AI/AO2) always present. You
can configure one, both, or
neither as AOs. Note: If you
configure both as AOs we
recommend you provide
isolation to avoid ground
loops which could affect
readings.

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

3.3 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:
