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.

with the following features:
• Eight single-pole single-throw (SPST) relay channels
• Switches up to 5 A at 18 VDC or 150 VAC, 0.2 A at 125 VDC,
or 3 A at 250 VAC
• – 40 to 70 °C operation
• 250 V CAT II continuous channel-to-channel and
rms
channel-to-ground isolation, verified by 2,300 V
dielectric withstand test

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,
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
