6ES7131-4BB01-0AA0 Siemens ET 200S High-Performance Digital Input Module SIMATIC DP
The Siemens 6ES7131-4BB01-0AA0 is a high-reliability 2-channel digital input module designed for the SIMATIC ET 200S distributed I/O system. Operating at 24 V DC, this compact module supports both sinking (NPN) and sourcing (PNP) sensor wiring configurations, making it ideal for flexible integration in factory automation, packaging, material handling, and process control applications.
As part of Siemens’ proven ET 200S modular I/O platform, the 6ES7131-4BB01-0AA0 delivers fast signal acquisition, diagnostic capabilities, and seamless communication via PROFIBUS DP or PROFINET (when used with compatible interface modules). It is widely deployed in industries requiring robust, space-saving, and service-friendly I/O solutions.
