Introduction

Section 2

This section provides information about the individual Units that make up the

C500 PC. First the names of all the parts of the PC are given, followed by

any details that apply to the Units that make up the PC. For a description of

how the Units fit together to become a PC, refer to 3-3 System Configura

tions. For information about the model numbers of any of the parts described

in this section, refer to Appendix C Standard Models.

CPU Rack

Expansion I/O Connector

Connects the CPU Rack

to an Expansion I/O

Rack. When not used,

cover with cap.

I/O Control Unit

An I/O Control Unit must be

mounted to the Rack in or

der to connect the CPU

Rack to an Expansion I/O

Rack.

The following figure shows the names of all the parts of the CPU Rack.

There are seven models of CPU Racks available for the C500 PC. Choose a

Backplane with 3. 5 (2 models), 6. 8 (2 models), or 9 I/O slots, depending on

your application. Connect the CPU Backplane to an Expansion I/O Rack via

the Expansion I/O Connector.

CPU Power Supply

The CPU executes the user program. The model available for the C500 PC

does not have a built-in Power Supply or Memory Pack. Choose the Power

Supply and memory pack suitable for your application. A peripheral device

connector and a memory pack compartment are provided.

The CPU is equipped with one connector for peripheral devices. A peripheral

device, such as the CPU-Mounting Programming Console, can be mounted

directly to the CPU and does not require a connecting cable. To mount the

CPU-Mounting Programming Console or any other peripheral device directly

to the CPU, follow these steps:

Detach the cover of the peripheral device connector with a standard

screwdriver.

Connect the CPU-Mounting Programming Console to the peripheral de

vice connector.

To ensure a positive connection, secure the Programming Console to

the CPU by tightening the mounting screws located on the surface of the

CPU

The CPU Power Supply is mounted to the rightmost slot of the CPU Rack.

Three models of Power Supplies are available: 100 to 120 VAC, 200 to 240

VAC, and 24 VDC. The following table summarizes the output capacity of the

three models and the current available for I/O Units mounted on the CPU

Rack.

Be sure to keep the total power consumed by all the Units mounted

on a Rack within the value stated in the table above. For example, do

not mount I/O Units with a total current consumption of 6 A to a Rack

supplied by a 7 A Power Supply. As shown in the table above, the

available current for I/O Units is only 5 A. For details concerning cur

rent consumption, refer to Section 4 System Connections.
