The Siemens 505-4316 24 VDC Input Module is a digital input card designed to interface 24-volt signals with a Siemens PLC system. It translates external 24 VDC signals from sensors, switches, and other devices into PLC-understandable data for real-time control and monitoring in industrial automation. Typical applications include reading 24 V sensors and switches in control panels, machine automation, and process control where reliable 24 V inputs are required.
