FieldPoint Operating Instructions
C
FP-RLY-421
Eight-Channel SPST Relay Module
These operating instructions describe how to install and use the
National Instruments cFP-RLY-421 relay module. For details on
configuring and accessing the cFP-RLY-421 over a network, refer
to the user manual for the FieldPoint network module you are
using.
Features
The cFP-RLY-421 is a Compact FieldPoint relay output module
with the following features:
•
Eight single-pole single-throw (SPST) relay channels
•
Switching capacity 1.5 A at 35 VDC or 250 VAC
•
LED relay status indicators
•
Hot swappable
•
– 40 to 60 °C operation
•
250 V
rms
maximum isolation voltage
•
2,300 V
rms
transient overvoltage protection
Power Requirement
The cFP-RLY-421 is powered by the FieldPoint network module
through the backplane bus. The cFP-RLY-421 is a high-power
consumption module, which may limit the number of I/O modules
that you can connect to a single network module.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
