↓

24 DC Inputs

↓

IC200UDR140 Processor

↓

User Application Logic

↓

16 Relay Outputs

↓

Motors / Solenoids / Contactors / Indicators

During operation, the controller monitors its input circuits, processes the received information according to the application program, and updates the output states.

The controller can therefore perform functions such as:

• Machine sequencing
• Start/stop logic
• Interlocking
• Timer operations
• Counter operations
• Alarm logic
• Equipment coordination
• Digital signal processing
• High-speed input functions where configured
• Relay-based output control
