2.3.1—Redundant Power Supplies
Two load sharing power supplies provide redundant power to the motherboard, CPU and I/O modules. The
MicroNet Plus power supplies are 2-slot wide each and are located at each end of the chassis in the
designated PS1 and PS2 slots.
2.3.2—Single CPU Options
The MicroNet Plus control system may be used in simplex mode with a single CPU module that must be
located in slot A1 of the main chassis. No other options are available.
2.3.3—Simplex Inputs and Outputs
Each I/O module has connectors on the faceplate. For analog and discrete I/O, cables connect the module
to a Field Terminal Module (FTM). The FTM is used to connect to the field wiring. For communication
modules, FTMs are not used. Cables are connected directly to the faceplate of the communications module.
The following diagram shows the flow of analog and discrete inputs from the field to the application.
