Product Description

The Siemens R120 CPU Module is a high-performance R120 Compact PLC designed for industrial automation and control applications. This R120 Controller Unit features 16 digital inputs and 14 digital outputs, supporting direct connection to up to 4 expansion modules for scalable I/O configurations. It integrates a built-in Ethernet port and RS485 interface for seamless communication with HMI, SCADA systems, and other devices. Operating within a voltage range of 20-28V DC, the R120 CPU functions reliably in temperatures from -20°C to +60°C, making it suitable for manufacturing, process automation, and energy management systems. Its compact design and robust construction offer excellent durability, while the absence of an integrated display and limited processing power for complex algorithms may require supplementary hardware. The device lacks a built-in screen but supports external touch panels. Typical applications include conveyor control, HVAC systems, and small-scale machinery automation, where its fast response time and compatibility with Siemens TIA Portal software are key advantages. The module does not include a battery backup but relies on external power stabilization for memory retention. Detection ranges for connected sensors vary based on configuration, typically supporting industry-standard proximity and photoelectric sensing distances.
