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.
Connecting Loads to the cFP-RLY-423
Connect two loads and an external power supply to one channel
of the cFP-RLY-423 as shown in Figure 2. Install a 1.5 A, 250 V
maximum, fast-acting fuse suitable for the load at the connected
IC terminal to protect the module and the load from damage.
