Siemens 6ES7131-0BL00-0XB0 SIMATIC CPU Module

Siemens 6ES7131-0BL00-0XB0 SIMATIC DP electronic module digital for ET 200B is a 32-channel digital input module that brings 24 V DC sensor signals into a SIMATIC DP distributed I/O network. Designed for ET 200B stations, it provides 32 digital inputs at 24 V DC and features a maximum input delay of 3 ms (from 0 to 1) to ensure rapid state capture in real-time automation. With a module width of 235 mm, it aligns with the standard ET 200B footprint and DP bus wiring. This spare-part device extends the digital input capacity of DP networks, enabling reliable monitoring of 24 V DC devices such as sensors, limit switches, and pushbuttons, and feeds clean, switch-type signals into the PLC for processing and control logic. In typical installations, it is mounted in control cabinets as part of a larger ET 200B DP I/O assembly and communicates with the CPU over the PROFIBUS DP network to support fast, deterministic input handling in industrial processes.
