Figure 2-13. 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 bank. 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 2-13 shows this optional
connection.
If your field I/O devices need to be powered separately, you can use the
terminals provided on each terminal base for such power supply
connections. Refer to the documentation that came with your terminal
base and I/O module for more information on powering your field I/O
devices.
Calculating Power for a FieldPoint Bank
The power requirements for a FieldPoint bank that uses an FP-1000 or
FP-1001 network module are calculated as follows:
Power = 1 watt + 1.15 *
∑
(I/O Module Consumption)
The operating instructions for each FieldPoint I/O module contain
power consumption information.
