FP-DI-330 and cFP-DI-330
Eight-Channel Universal Digital Input Module
These operating instructions describe how to install and use the
National Instruments FP-DI-330 and cFP-DI-330 digital input
modules (referred to inclusively as the [c]FP-DI-330). For
information about configuring and accessing the [c]FP-DI-330
over a network, refer to the user manual for the FieldPoint network
module you are using.
Features
The [c]FP-DI-330 is a FieldPoint digital input module with the
following features:
•
Eight digital input channels
•
Universal inputs that work with any voltage from 5 V TTL
level up to 250 VDC/VAC
•
Compatibility with sourcing, sinking, or power-sensing
applications
•
On/Off LED indicators
•
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-DI-330
The FP-DI-330 mounts on a FieldPoint terminal base (FP-TB-x),
which provides operating power to the module. Installing the
FP-DI-330 onto a powered terminal base does not disrupt the
operation of the bank.
