Overview
The National Instruments [c]FP-AI-1xx devices are versatile analog
input modules for Compact FieldPoint and FieldPoint that can be
used to measure voltages ranging from the millivolt level to the
120 V high-voltage level in applications such as battery-pack
monitoring, fuel-cell testing, and general measurement from
transducers. These modules can also measure 0 to 20 or 4 to 20 mA
current loops from industrial sensors and transmitters. All the
modules include overranging and onboard diagnostics to ensure
trouble-free installation and maintenance. The modules measure and
linearize signals on-board to return scaled values to your control
or monitoring software. The [c]FP-AI-1xx modules come with
NIST-traceable calibration certificates, ensuring accurate and reliable
analog measurements.
Smart I/O Modules
With [c]FP-AI-1xx analog input modules, you can directly connect to
your industrial sensors or units under test and get high-accuracy
measurements. The I/O modules filter, calibrate, and scale raw sensor
signals to engineering units, as well as performing self-diagnostics to
look for problems with the module or the wiring. With FieldPoint
modules, your software application reads a linearized, calibrated, and
scaled value from the I/O module, eliminating the error-prone step of
converting binary values to voltage or current values. For increased
accuracy and noise rejection, the [c]FP-AI-110 and [c]FP-AI-111 use a
16-bit delta-sigma ADC with an integrated lowpass filter on each
channel, which you can configure for 50 Hz, 60 Hz, or no rejection.
With high-accuracy 12-bit ADCs or 16-bit delta-sigma ADCs on the
I/O modules, you also get instrument-quality measurements on an
industrially rugged, distributed, embedded system.
[c]FP-AI-1xx modules offer a variety of update rates to fit your
application, ranging from 0.66 to 360 Hz. These rates vary based on
the module used and on the noise filter settings selected on the
module. Overall data throughput depends on software loop speeds
and network speeds. With overranging and underranging, the
[c]FP-AI-1xx analog input modules can measure inputs or sensors
that are not calibrated to standard ranges. For example, when
configured for an input range of 4 to 20 mA, the modules actually
measure inputs from 3.5 to 21 mA.
Analog Input Modules for
Compact FieldPoint and FieldPoint
Isolation
[c]FP-AI-1xx modules feature optical bank isolation with 2,300 V
rms
of breakdown isolation. In addition, the [c]FP-AI-100, [c]FP-AI-102,
and [c]FP-AI-110 modules provide double insulation for up to
250 V
rms
of operational isolation. Compact FieldPoint can safely be
used in applications where hazardous voltages are present with the
cFP-CB-1 connector block. FieldPoint can safely be used in
applications where hazardous voltages are present with the FP-TB-x
terminal base. These Compact FieldPoint and FieldPoint modules do
not have channel-to-channel isolation.

Ordering Information
Field I/O Connections
Compact FieldPoint and FieldPoint modules include a built-in
power distribution bus that provides multiple power connections on
the module. A field-wired power supply connected to the voltage (V)
and common (C) terminals is internally connected to a power
distribution bus that provides additional breakout terminals for
voltage supply (V
SUP
) and common (COM). These terminals provide
a convenient way to distribute power to field devices that require
external power.
Each input channel on the AI-100 and AI-110 has four terminals:
1. Voltage input (V
IN
)
2. Current input (I
IN
)
3. Common (COM)
4. Power connection to power field devices or loop powered
current loops (V
SUP
)
The AI-111 has:
• 16 current input terminals (I

)
• 8 common terminals (COM)
• 8 power connections for field devices or current loops (V
