Siemens 6ES7-131-1BL01-0XB0 SIMATIC S7-300 IO Module

Siemens 6ES7-131-1BL01-0XB0 is a SIMATIC ET 200L digital input module with 32 DI channels at 24 V DC, designed for distributed I/O in SIMATIC S7-300 systems. This 32-channel DI module belongs to the ET 200L family and serves as the input interface for field devices such as sensors and pushbuttons, converting 24 V DC signals into PLC-readable logic states. Identified by the part number 6ES7-131-1BL01-0XB0, it is cataloged as a spare part for ET 200L components and is intended for use in distributed I/O stations to expand digital input capacity. Suitable for use in factory automation, machine control, and process monitoring setups that rely on S7-300 controllers, the module integrates with ET 200L distributed I/O installations to support scalable expansion of digital inputs across a site. Key specifications verified include 32 DI channels and 24 V DC input level, making it a straightforward replacement or upgrade for existing ET 200L installations that require additional 24 V digital inputs.
