Selection Guide

• Choose this model if you have AC power and relay loads.
• For DC power and transistor outputs, select the DC/DC/DC version.
• Check if you need more than 16 I/O modules – this CPU supports up to 8.
• If you need PROFIsafe, consider a fail-safe CPU.
• For OPC UA, remember to purchase the “Basic” license.
• Order a SIMATIC Memory Card for large data logging or firmware updates.
