Siemens 6ES7141-4BH00-0AA0 Digital Input Module

The Siemens 6ES7141-4BH00-0AA0 SIMATIC DP electronic module is a 16-channel digital input module for the ET 200 PRO distributed I/O family, designed to accept 24 V DC field signals and feed their on/off state to the PLC over the SIMATIC DP backplane. It includes module diagnostics that monitor each input channel for faults, reports status via the backplane, and supports fast, deterministic reading of input states—critical for synchronous control of sensors, pushbuttons, and switches in automation lines. In ET 200 PRO configurations, this module is typically used together with a bus module and a dedicated connection module; the IO connection module 6ES7194-4CB50-0AA0 is ordered separately. Key specs include 24 V DC supply operation and 16 DI capability within the SIMATIC DP ecosystem, making it a common choice for factory floor sensing on conveyors, material handling, packing stations, and other industrial automation tasks.
