Siemens 6SE3211-1DA40

The Siemens part number 6SE3211-1DA40 is a sophisticated 16-channel digital input module tailored for the SIMATIC S7-200 and S7-300 series of programmable logic controllers (PLCs). This essential component facilitates seamless integration with external devices such as sensors and actuators, supporting both DC and AC inputs with a voltage range of 0-30V DC and 0-250V AC. With a robust maximum current rating of 1A per channel for DC inputs and 0.5A for AC inputs, it excels in demanding industrial environments, offering a high level of noise immunity to ensure reliable performance. The module is easily configured through Siemens' STEP 7 software, allowing users to define input/output assignments and program logic controls with precision. Installation requires careful adherence to wiring and power supply guidelines, ensuring optimal function by qualified professionals. While the module does not generate error codes independently, it is designed to trigger alarms within the PLC if misconfigurations or device issues arise, providing a comprehensive diagnostic support system for troubleshooting and maintenance.
