Product details

CPU classification and environmental rating

The Siemens 6AG1211-1BD30-2XB0 is a SIPLUS S7-1200 CPU with extended temperature range from -40 °C to 70 °C, rated for 24 V DC supply (20.4 V to 28.8 V). It integrates 1 MB load memory (expandable via SIMATIC Memory Card) and supports FBD and LAD programming languages. A maintenance-free EEPROM holds the entire project, with a typical backup time of 240 hours.

Hardware profile and connectivity

Network connectivity is limited to TCP/IP as a server; there is no onboard PROFIBUS, MODBUS, or AS-Interface. The CPU does support forced values and PID control. For analog inputs, the module accepts 0 to +10 V signals and supports 2-wire sensors. The signal thresholds are 5 V DC at 1 mA for logic 0 and 15 V DC at 2.5 mA for logic 1.

This SIPLUS CPU carries cULus, CE, and UL approvals, satisfying safety certification for North American and European panel builds.
