6ES7131-4BF00-0AA0 Siemens SIMATIC ET 200S Digital Input Module 8DI 24 V DC
The Siemens 6ES7131-4BF00-0AA0 is the SIMATIC ET 200S digital electronic module 8DI DC24V: a 15 mm wide input module with 8 digital inputs for 24 V DC signals, supplied as 1 unit per pack. It plugs into an ET 200S terminal module and reads sensors, push-buttons and limit switches in distributed I/O stations. Siemens now supplies this module as a spare part only, and Atlantech Drives sources it to keep existing ET 200S installations running.
