The System 450 control module is the supervisor of your control system and the interface for the system’s inputs, supply power, and outputs.
Figure 1 shows an example System 450 control module. See Table 1 and Table 1 for information on all of the available control modules.

All System 450 control systems require a control module to set up the control system’s inputs and outputs, monitor the control system’s status, and control the system’s outputs.
System 450 control modules can monitor up to three inputs and control up to 10 outputs in any combination of relay and analog outputs provided by expansion modules.
