Siemens 6ES7131-0BL10-0XB0 Programmable Logic Controller Module

Siemens 6ES7131-0BL10-0XB0 is a SIMATIC DP digital input module engineered for the ET 200B distributed I/O system. It provides 32 digital inputs at 24 V DC and features a fast 0.2 ms input delay for high-speed sensing. Communicating over a PROFIBUS DP network, it supports data transmission up to 12 Mbit/s. The module measures 235 x 130 x 60 mm and weighs about 800 g, designed for installation in ET 200B racks to expand the PLC’s input capabilities. Used to monitor field sensors such as limit switches, pushbuttons, and other 24 V DC devices, it feeds real-time signals into the SIMATIC controller for immediate logic decisions. Part of the SIMATIC DP family, this module integrates with Siemens PLCs via the ET 200B base station and PROFIBUS DP interface to enable scalable, distributed input collection in automation projects. Suitable applications include manufacturing lines, conveyors, robotic workcells, and packaging systems where reliable 24 VDC digital inputs and fast response are required.
