The Siemens 3RK2400-1FE00-0AA2 is a compact and versatile Slimline module designed for seamless integration into control cabinet operations. This digital module is part of the AS-Interface system and serves as an A/B slave with a configuration of 4 digital inputs and 3 digital outputs. The inputs are suitable for 2- and 3-wire sensor connections and utilise PNP transistor input circuits, ensuring compatibility with a wide range of industrial sensors.
With an input voltage range of 20 to 30 V for the sensor supply, this module is short-circuit and overload resistant, providing a reliable and secure solution for various automation tasks. The digital outputs operate at 24 V DC and are capable of handling an aggregate current of up to 4 A, with each semiconductor output rated at 2 A at DC-13, at 24 V. The outputs are also equipped with built-in short-circuit, induction, and polarity reversal protection, as well as a watchdog feature for enhanced operational safety.
The module's status is easily monitored through its yellow LED indicators for I/Os, a green LED for AS-Interface, and a red LED for fault indication. Designed for easy installation, the 3RK2400-1FE00-0AA2 can be mounted on a 35 mm standard rail or wall-mounted using push-in lugs, and it accommodates a range of conductor cross-sections for flexible wiring options.
With a slim width of 45 mm, this module is an efficient space-saver in control cabinets, while its robust construction ensures it can operate in a wide range of ambient temperatures, from -25 to +70 °C during operation and -40 to +85 °C during storage. The module is also IP20 rated, signifying protection against solid objects larger than 12.5 mm but not against liquids, making it suitable for indoor environments where exposure to moisture is not a concern.
The Siemens 3RK2400-1FE00-0AA2 is a reliable choice for those seeking a high-quality, durable module that delivers efficient performance and flexibility in a variety of industrial automation applications.
