Siemens 6ES7131-6BF00-0BA0 Digital Input Module

Siemens 6ES7131-6BF00-0BA0 Digital Input Module is a SIMATIC ET 200SP DI module that provides eight 24 V DC digital inputs (DI 8x 24 V DC STANDARD). It is designed to mount to a BU type A0 base unit in the ET 200SP system, with color code CC01, and offers built-in module diagnostics for quick fault identification. Each of the eight channels accepts 24 V DC signals, enabling straightforward connection of common industrial sensors such as pushbuttons, limit switches, and general-purpose 24 V digital devices. The module integrates with SIMATIC controllers via the ET 200SP backplane and is configured in STEP 7/TIA Portal as digital inputs, supporting reliable, scalable expansion of I/O for compact automation installations.
