Product Description: Siemens 6ES7131-4BD01-0AB0

The Siemens 6ES7131-4BD01-0AB0 is a digital input module from the SIMATIC ET 200S distributed I/O system. Classified as DI 8×24 V DC ST, it provides 8 digital inputs for 24 V DC signals. Designed in a compact 15 mm-wide electronics module form factor, it enables high-density digital input expansion for ET 200S stations. This standard module is optimized for use in automation systems requiring fast and reliable acquisition of binary signals such as sensors, switches, and pushbuttons. The module supports diagnostics functions, including wire break detection (when used with the appropriate terminal modules), and is fully configurable via the Siemens TIA Portal or STEP 7.
