FieldPoint Operating Instructions
cFP-RLY-425
Eight-Channel SPST Relay Module
These operating instructions describe how to install and use the
National Instruments cFP-RLY-425 relay module. For information
about configuring and accessing the cFP-RLY-425 over a network,
refer to the user manual for the FieldPoint network module you are
using.

Power Requirement
The cFP-RLY-425 is powered by the FieldPoint network module
through the backplane bus. The cFP-RLY-425 requires up to
1.45 W of power,
1
which may limit the number of I/O modules that
you can connect to a single network module.
Before you configure a FieldPoint system that uses a cFP-RLY-425
module, calculate the total power consumption of the I/O modules
on the FieldPoint bank. Power requirements are listed in the
Specifications
sections of the operating instructions for each
I/O module. The network module user manual lists the maximum
1
1.45 W is the maximum power requirement. Most applications require less power.
