cFP-RLY-421 4 ni.com
Table 1 lists the terminal assignments for the signals of each
channel.
All of the COM terminals are connected internally and all of the
V
SUP
terminals are connected internally. NI does not recommend
using them with the cFP-RLY-421.
Caution Cascading power between two modules defeats
isolation between those modules. Cascading power from
the network module defeats all isolation between
modules in the FieldPoint bank.
