Product Details 

The Siemens U-55N is a legacy 16-point discrete input module engineered for industrial programmable logic controller systems. Operating as an interface component within a PLC rack assembly, it is designed to monitor, receive, and process binary signals from field-level hardware, such as limit switches, sensors, or push buttons. It translates external electrical signals into low-voltage logic data that the central processing unit can interpret, enabling robust control loop execution across vintage automated setups.
