Connecting Power To The Fieldpoint System - National Instruments FieldPoint FP-1300 User Manual

Connecting Power to the FieldPoint System

Before you power up the FP-1300 on a process-critical CAN network, make sure
Caution
that the FP-1300 and the CAN network have the same baud rate. Also make sure that the
FP-1300 is using a unique arbitration ID.
Caution Cascading power from neighboring bases or network modules defeats isolation
between cascaded modules.

Complete the following steps to connect power to the FieldPoint system:
1. Connect the 11–30 VDC power supply leads to the V and C terminals
of the network module. Connect the positive lead to V and the negative
lead to C.
2. Connect power to the FieldPoint modules that require external power
for inputs or outputs (such modules include output modules, counter
modules, PWM, PG, and QUAD). Refer to the operating instructions
of the I/O module for power requirement details. You can power a
module by connecting the V and C inputs on its terminal base to a
separate power supply, connecting the V and C outputs of a
neighboring terminal base or network module, or using a combination
of both methods. If you want to power field I/O devices from a terminal
base, supply power to the terminal base, then connect the terminal base
V and C output terminals to the field device.
Figure 2-17 shows an example of a FieldPoint system wired to power
sources.
