Siemens 6ES5435-7LB11 Digital Input Module

Siemens 6ES5435-7LB11 Digital Input Module is a SIMATIC S5 DI card for the S5-115U family, delivering 16 digital input channels that accept 115 V AC or 115 V DC signals. The inputs are floating and isolated, arranged in eight‑channel groups to simplify field wiring and backplane integration. Designed for use with the S5-115U PLC, this 435‑series module expands the controller’s input capacity and is commonly employed to read switches, sensors, and other 115 V signaling sources in factory automation and process monitoring applications. The card plugs into the standard S5 backplane and provides sixteen independent input points, enabling straightforward deployment in environments where 115 V digital signals are standard.
