Isolation

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

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.

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

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:

3. Common (COM)

4. Power connection to power field devices or loop powered

The AI-111 has:

•8 common terminals (COM)

The AI-102 module has:

• 16 common terminals (COM)
