Use a 5–30 VDC external power supply for the input channels.
The power supply must provide enough current to power all of the
input channels and all of the field devices on the output channels.
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 between the external
power supply and the V or V
SUP
terminal on each channel. Install
a 1 A maximum, fast-acting fuse suitable for the load at the V
OUT
terminal. The detailed wiring diagrams in this document show
fuses where appropriate.
Table 1 lists the terminal assignments for the signals of each
channel. Terminal assignments are also listed on the side panel of
the cFP-CTR-502 and under the slide-in card on the front of the
FP-CTR-502.
