Power Supply Module
The power supply module is required for the basic unit to use the 115 V/230 V AC supply voltages
to generate the 24 V DC operating voltages.
External I/O Modules
The following external I/O modules can be used:
•
Failsafe digital input and output modules
•
Non-failsafe digital input and output modules from the S5-100U
•
Non-failsafe analog input and output modules from the S5-100U
You can use these modules to create and record variables (currents and voltages).
•
Non-failsafe communications modules (CP - communications processor)
You can use this module to output message texts with the date and clock time to a connected
printer. You can also use this module as an interface to external systems.
