FP-AI-112 and cFP-AI-112
16-Channel, 16-Bit Analog Input Modules
These operating instructions describe how to install and use the
FP-AI-112 and cFP-AI-112 analog input modules (referred
to inclusively as the [c]FP-AI-112). For information about
configuring and accessing the [c]FP-AI-112 over a network, refer
to the user manual for the FieldPoint network module you are
using.
Features
The [c]FP-AI-112 is a FieldPoint analog input module with the
following features:
•
16 analog voltage input channels
Eight voltage input ranges: 0–1 V, 0–5 V, 0–10 V, ±60 mV,
•
±300 mV, ±1 V, ±5 V, and ±10 V
•
16-bit resolution
•
50 and 60 Hz filter settings
•
250 V
CAT II continuous channel-to-ground isolation,
rms
verified by 2,300 V
•
–40 to 70 °C operation
•
Hot swappable
Installing the FP-AI-112
The FP-AI-112 mounts on a FieldPoint terminal base (FP-TB-x),
which provides operating power to the module. Installing the
FP-AI-112 onto a powered terminal base does not disrupt the
operation of the FieldPoint bank.
