Siemens 6ES7131-1BH11-0XB0 ET 200M Digital Input Block

The Siemens 6ES7131-1BH11-0XB0 electronic block provides 16 digital input channels for the SIMATIC ET 200M distributed I/O system. This electronic module reads 24 V DC signals from field sensors and pushbuttons. It offers electrical isolation between the input channels and the backplane bus. The block installs directly on a terminal module within the ET 200M station.

Technical Specifications

The Siemens 6ES7131-1BH11-0XB0 electronic block features 16 digital inputs arranged in two isolated groups of eight. Each input operates with a nominal voltage of 24 V DC and draws approximately 7 mA. The module includes an input delay of 1.2 ms to 4.8 ms for contact debouncing. It consumes roughly 15 mA from the backplane bus. The block’s LED indicators display the status of each input channel.
