Rack Options
Racks are available in 4-slot, 8-slot, and 12-Slot
versions. Racks are interchangeable between the
Controller rack and an IO expansion rack (C50
CPU only), and all three versions shown in Figure
6 are available for either purpose.

Power Supply
The P01 Power Supply, shown in Figure 7, provides
5 Vdc and 24 Vdc to the backplane connectors in the
local and remote racks. The Power Supply is
identical for the Controller Rack and for I/O
expansion racks(C50 CPU only), and for all rack
versions (4-slot, 8-slot, and 12-Slot).
The less expensive lower capacity P02 power supply
is available for reduced I/O applications. See page
37 to determine correct power supply.
Each power supply includes an internal 5.0-amp fuse
that is not field-replaceable. (An external fuse may
be added by the user.)
Items shown with key numbers:
1. Voltage test points (P01model only)
2. AC Input terminal block
3. Wiring label
4. Grounding lug (Reference; lug is not part of
Power Supply; it is staked to bottom of Rack.)
