sampling rate is faster than the rate at which the network module 
polls the [c]FP-AI-110 for data. 

The [c]FP-AI-110 has two green status LEDs, POWER and 
READY. After you insert the [c]FP-AI-110 into a terminal base or 
backplane and apply power to the connected network module, the 
green POWER LED lights and the [c]FP-AI-110 informs the 
network module of its presence. When the network module 
recognizes the [c]FP-AI-110, it sends initial configuration 
information to the [c]FP-AI-110. After the [c]FP-AI-110 receives 
this initial information, the green READY LED lights and the 
module is in normal operating mode. A blinking or unlit READY 
LED indicates an error condition.

You may need to upgrade the FieldPoint firmware when you add 
new I/O modules to the FieldPoint system. For information on 
determining which firmware you need and how to upgrade your 
firmware, go to

Read the following information before 

attempting to connect the [c]FP-AI-110 to any circuits 
that may contain hazardous voltages.

This section describes the isolation of the [c]FP-AI-110 and 
its compliance with international safety standards. The field 
wiring connections are isolated from the backplane and the 
inter-module communication bus. The isolation barriers in the 
module provide 250 V

 Measurement Category II continuous 

channel-to-backplane and channel-to-ground isolation, verified by 
2,300 V

 The [c]FP-AI-110 

provides double insulation (compliant with IEC 61010-1) for

A hazardous voltage is a voltage greater than 42.4 V

peak

 or 60 VDC. When a 

hazardous voltage is present on any channel, all of the channels must be considered 
to be carrying hazardous voltages. Ensure that all circuits connected to the module 
are inaccessible to human touch.
