Siemens 6ES7131-1BL00-0XB0 Programmable Logic Controller Module

Siemens 6ES7131-1BL00-0XB0 is a SIMATIC ET 200L electronic block that provides 32 digital input channels (DI) rated for 24 V DC, designed to expand the digital sensing capabilities of a PLC-based automation system by interfacing directly with field devices. As part of the ET 200L distributed I/O family, the module integrates into the ET 200L enclosure and communicates with a central controller via SIMATIC DP, enabling straightforward connection of sensors such as switches and proximity devices to a Siemens PLC network. The official specification specifically names it as an ET 200L electronic block for 32 DI, 24 V DC operation, reinforcing its role as a 32-channel input block within the DP-enabled ET 200L system. Lifecycle notes from Siemens and distributors indicate this model is discontinued, with some listings describing it as deleted without replacement, reflecting a phase-out in favor of newer ET 200L modules.
