Power Supply Examples
Introduction
A POINT Guard I/O system includes an adapter, I/O modules, mounting bases,
and power distribution modules. POINT I/O adapters have built-in power
supplies. All POINT I/O modules are powered from the POINTBus backplane
by either an adapter or expansion power supply.
POINTBus Backplane
The POINTBus backplane includes a 5V communication bus and field power
bus that get their power from the adapter or power supplies. To choose which
types of power supplies meet your requirements, you
must
consider the power
consumption requirements for the 5V and 24V bus when designing a
POINTBus backplane.
Choose from these power supplies for the POINTBus backplane and field
power:
•
Use the 1734-EP24DC expansion power supply with the 5V and/or 24V
bus.
•
Use the 1734-EPAC expansion power supply to pass 120/240V AC field
power to the I/O modules to the right of it.

Observing Precautions for Safe Use
IMPORTANT
If you use the 1734-EPAC expansion power supply to the
left of the POINT Guard I/O modules, you must use a
1734-FPD field power distributor or 1734-EP24DC
expansion power supply to isolate POINT Guard I/O field
power from the AC field supply.
Establishing and maintaining communication
(connection) between the module and the controller
requires 5V POINTBus power.
