Powering the FP-1001

NOTE:  Terminal bases must be connected to the FP-1001, 
and the baud rate switch must be set, before power is applied to 
the FP-1001. 

An 11-30 VDC power supply is required by each FieldPoint stack. 
The network module filters and regulates this supplied power and 
provides power for all the I/O modules in the stack. Therefore you 
need not provide power separately to each FieldPoint I/O module 
in the stack. If your field I/O device needs to be powered 
separately, you can use the terminals provided on each terminal 
base for such power supply connections.

The power connector is a 4-pin screw terminal connector whose 
pinout is shown in Figure 7.

Figure 7.  

FP-1000 and FP-1001 Power Connector Pinout

The two terminals labeled V are internally connected on the 
network module, as are the two terminals labeled C. Power must be 
applied to one V and C pair for operation of the FieldPoint system. 
If you want to power your field I/O devices from the same power 
supply, the second V and C pair provides a convenient means of 
connecting power to the V and C terminals of a terminal base. 
Figure 7 shows this optional connection.
