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.
