Key Features of CPU 1212C DC/DC/DC

1. Integrated I/O & Power Supply

• 8 digital inputs (24V DC, sink/source)
• 6 digital outputs (24V DC, 0.5A each, transistor-based)
• DC power supply (20.4–28.8V DC)
• No analog I/O onboard (requires expansion modules)

2. Performance & Memory

• 75 KB work memory (for program and data)
• 2 MB load memory (for project storage)
• Execution speed: ~0.1 ms per 1,000 binary instructions
• Onboard real-time clock (RTC) for time-based operations

3. Communication Interfaces

• PROFINET (1x RJ45 port) for:
• Programming (TIA Portal)
• HMI connectivity (KTP, TP, Comfort Panels)
• PROFINET IO communication (as controller or device)
• No built-in RS485/RS232 (requires CM 1241 for serial communication)

4. Expandability

• Supports up to 5 signal modules (SM) or communication modules (CM/CP)
• No built-in analog I/O (requires SM 1231 for AI / SM 1232 for AO)

5. Programming & Diagnostics

• Programmable with TIA Portal (STEP 7 Basic/Professional)
• Web server functionality for remote diagnostics
• LED status indicators (RUN/STOP, ERROR, MAINT, etc.)

6. Typical Applications

• Conveyor control systems
• Packaging machines
• Material handling systems
• Small process control applications
