You can use a 5–250 VDC external power supply to power field 
devices. Connect the positive lead of the external power supply to 
both V terminals and the negative lead to both C terminals. Ensure 
that the current through both V terminals can never exceed 2 A.

Install 2 A maximum, fast-acting fuses between the external power 
supply and the V terminals. The wiring diagrams in this document 
show fuses where appropriate.

Table 1 lists the terminal assignments for the signals associated 
with each channel. The terminal assignments are the same for the 
FP-TB-

x

 terminal bases and the cFP-CB-

x

 connector blocks.

If you are using the cFP-DI-330 in a 

hazardous voltage

 

application, you must use the cFP-CB-1 connector block or a 
suitable hazardous voltage cable. A hazardous voltage is a voltage 
greater than 42.4 V

peak

 or 60 VDC.

Caution

Ensure that hazardous voltage wiring is 

performed only by qualified personnel adhering to local 
electrical standards.

Caution

Do 

not

 mix circuits with hazardous voltages and 

human-accessible circuits on the same module.

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.
