Expansion Modules, Module Assemblies, and Outputs

System 450 expansion modules provide additional outputs to expand your control
systems and meet your specific application requirements.
A System 450 control system can provide up to ten outputs, which can be any
combination of relay and analog outputs. Expansion modules are available with
one or two relay outputs, or with one or two analog outputs. See Table 11 on
page 62 for information on the System 450 modules that can be used in a standard
control system.

Module Assemblies, Output Types, and Output Numbers

You can easily plug System 450 modules together using the 6-pin connectors
located on the sides of the modules' housings and mount these module assemblies
on standard 35 mm DIN rail (recommended) or directly to a hard, even surface.
See Mounting on page 36 for more information.
Figure 4 shows a System 450 module assembly example, the module positions, the
output types, and the automatically assigned output numbers used in the System
Setup screens in the control module UI.
The control module is always mounted on the left side of the module assembly. If a
System 450 power module is used, the power module is always plugged into the
right side of the control module. If expansion modules are used, they can be
plugged into the assembly in any order on the right side of the power module (or
the right side of the control module, if a power module is not used in the
assembly). See Assembling System 450 Modules on page 35 for more information.
