The Siemens 6ES7131-1BH11-0XB0 is a SIMATIC DP electronic block for the ET 200L distributed I/O system. It provides 16 digital inputs at 24V DC, designed for industrial control panels requiring a compact input expansion. The module is expandable up to 16 channels using the TB 16SC terminal block or Smart Connect connection system, per the datasheet function.
Inputs are rated at 24V DC, suitable for standard sensor or pushbutton signals in an industrial environment. The expandable nature allows the unit to serve as a single-block building block for up to 16 digital channels, matching the footprint of a single remote I/O station on the ET 200L backplane.
