Product Overview

Siemens 6ES7374-2XH01-0AA0 is the SIMATIC S7-300 SM 374 simulator module. It provides 16 switches and 16 LEDs for simulating digital inputs, digital outputs, or a mixed arrangement of eight inputs and eight outputs.

The exact official Siemens product record identifies this item as a spare part and shows PM410: Product cancellation effective since 2024-10-01. Procurement should therefore include an exact-order-number check and a review of the installed S7-300 configuration.

Commercial Status

Verified Technical Data

System Fit and Applications

• Commissioning and functional testing of compatible SIMATIC S7-300 digital I/O configurations.
• Training or maintenance work requiring switch-driven input and LED output simulation.
• Exact-part replacement in installed systems that specify the SM 374 order number.

Compatibility and Procurement Checks

• Match the complete 6ES7374-2XH01-0AA0 order number and installed S7-300 rack configuration.
• Confirm the required simulation mode before configuration or replacement.
• Review switch and LED assignment and verify the corresponding STEP 7 hardware setup.
• Because cancellation is effective, confirm condition, warranty, stock and replacement planning in writing.
