Connect
the external power supply to multiple V and V
SUP
terminals and
to multiple C and COM terminals as needed to ensure that the
maximum current through any terminal is 2 A or less.
Install a 2 A maximum, fast-acting fuse (F2A 250V) between the
external power supply and the V
SUP
terminal on each channel.
Install a 2 A maximum, fast-acting fuse suitable for the load at the
V
OUT
terminal. Figure 3 shows fuses where appropriate.
Table 1 lists the terminal assignments for the signals associated
with each channel. Terminal assignments and wiring diagrams are
also listed on the side panel of the cFP-DO-403 and under the
slide-in card on the front of the FP-DO-403 module.
National Instruments recommends that you wire the external
power supply to multiple V
SUP
and COM terminals. Figure 3
shows how to connect two output channels to loads.
Wiring for Low-Current Applications
If your application requires 2 A or less combined current through
all channels of the [c]FP-DO-403, you can wire your application
as shown in Figure 3. Install a 2 A maximum, fast-acting fuse
(F2A 250V) between the external power supply and the V terminal
as shown.
