Specification & Description
The Siemens RF120C Communications Module is a state-of-the-art RFID interface designed to seamlessly integrate with the SIMATIC S7-1200 series. This compact module is engineered to facilitate efficient and reliable communication between control systems and RFID readers, making it an essential component for a wide range of industrial automation applications.
With its robust design, the RF120C can withstand the rigours of industrial environments, operating reliably within a temperature range of 0 to 55°C. The module supports a supply voltage range of 20 to 30 V dc, ensuring flexibility and compatibility with various power systems. Its low current consumption, typically 0.03 A without connected devices, makes it an energy-efficient choice for continuous operation.
The RF120C boasts a sleek profile with dimensions of 30 mm in width, 100 mm in height, and 75 mm in depth, and a net weight of just 0.15 kg, allowing for easy installation in space-constrained areas. It is designed for mounting on an S7-1200 rack, ensuring a secure and stable connection.
This communications module is equipped with a RS422 interface, allowing for the connection of one reader and supporting a maximum cable length of 1000 m for extended reach within industrial setups. The module's display features 4 LEDs for reader connection status and 1 LED for device status, providing clear and immediate visual feedback on operational status.
The RF120C is designed for acyclic communication and does not support the addressing of a transponder file handler. However, it does support S7 communication protocols, making it a versatile component for various applications. The module is parameterised using HSP and is programmed through a library of functions, ensuring ease of configuration and management.
With a Mean Time Between Failures (MTBF) of 196 years, the RF120C is a reliable choice for long-term operation. It is certified with CE, FCC, cULus, KCC, C-Tick, and FM standards, and also meets IECEx requirements for certain hazardous environments, marked as Ex: II 3G Ex nAA IIC T4 Gc.
The Siemens RF120C Communications Module is an essential component for businesses looking to streamline their RFID communication within industrial automation systems, offering durability, efficiency, and reliability.
