Wiring the [c]FP-PWM-520
The FP-TB-x terminal base has connections for each of the eight
output channels and for an external power supply to power the
output channels and field devices. The cFP-CB-x connector block
provides the same connections. Each channel has one output
terminal (V
OUT
), one supply terminal (V
SUP
), and two common
terminals (COM). All eight channels are referenced to the COM
terminals. The V and V
SUP
terminals are all internally connected,
as are the C and COM terminals.
Table 1 lists the terminal assignments for the signals of each
channel. Terminal assignments are also listed on the side panel
of the cFP-PWM-520 and under the slide-in card on the front of the
FP-PWM-520. Connect to the terminals using the terminal base,
connector block, or other connectivity accessory.
Use a 5 VDC or 10–30 VDC external power supply for the output
channels. The power supply must provide enough current to power
all of the loads on the output channels, up to a maximum of 1 A per
channel. 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.
