Combined functionality When these two modules are used together, they provide a complete input/output interface for S7-300 PLCs. The input module converts digital signals from an external source into binary digital data that can be processed by the PLC. The output module converts binary digital data generated by the PLC into digital signals that can control external devices such as relays, solenoids or LEDs.
Applications This combination of modules is used in a wide range of automation applications, including:
Industrial process control
Factory automation
Material handling systems
HVAC (Heating, Ventilation and Air Conditioning) Systems
Lighting systems
