Siemens 6ES54308MC11 8-Channel Digital Input Module

Siemens 6ES5430-8MC11 is an 8-channel digital input module for the SIMATIC S5 430-series systems. It provides eight isolated input channels designed to accept 115 V AC field signals, intended for use with S5-90U, S5-95U, and S5-100U controllers as well as ET 100U and ET 200U backplanes. The card plugs into standard S5 I/O backplanes and features galvanic isolation between the inputs and the backplane to help protect the controller and simplify wiring in multi-sensor installations. As an 8DI module in the 430 family, it expands digital input capability for legacy Siemens automation setups, enabling reliable status capture from discrete devices such as sensors and switches within compatible S5/ET ecosystems. The 6ES5430-8MC11 designation corresponds to the eight-input variant of the digital input modules, offering a straightforward, drop-in expansion option for Siemens-based control architectures.
