An auxiliary 24V dc power supply provides power to the POINTBus backplane and I/O modules. You can connect up to 17 I/O
modules and an adapter with a maximum of 10 A field power, using the auxiliary power.
The ArmorPoint field power distributor (1738-FPD) discontinues the I/O circuit power bus in order to change the field power
source for I/O modules to the right of it. This allows a broad range of voltage inputs in the I/O assembly.
The auxiliary power supports up to 17 I/O modules and an adapter with a maximum of 10 A field power. The 24V dc expansion
power unit (1738-EP24DC) extends the backplane bus power to support up to 17 more I/O modules. Connect additional expansion
power units to expand the I/O assembly up to the maximum of 63 I/O modules.
