The Bosch Rexroth S20-SSI-AO-1/1 (R911172544) is a sophisticated IO module designed with a modular and compact structure, ensuring easy handling and rapid installation. This device is specifically engineered to fit seamlessly into control cabinets or field setups, thanks to its space-saving technology that is suitable for top hat rail mounting. Its robust design incorporates forced ventilation through an axial fan, which contributes to the module's reliable performance in various operational conditions. The S20-SSI-AO-1/1 module stands out for its ability to interface with absolute encoders via an SSI connection, managing an impressive encoder resolution of up to 32 bits. It accommodates both gray and binary code inputs and supports a high transmission frequency of up to 2 MHz, making it highly versatile for different data acquisition scenarios. Additionally, the module features an analog output that can be employed for setting values in diverse drive systems such as electric or hydraulic drives. Equipped with current and voltage measuring ranges, the S20-SSI-AO-1/1 also offers diagnostic and status indicators that enhance its functionality and reliability in monitoring tasks. The device is capable of detecting the position through absolute encoders while also providing options such as rotation direction reversal for comprehensive control over motion applications. This IO module is part of a product group identified by the ctrlX configurator from Bosch Rexroth, highlighting its compatibility with open communication standards which ensures maximum availability when integrated into machine concepts. The innovative assembly and installation concept of this IO technology underscores its user-friendly nature, allowing for individual combination of modules to meet bespoke requirements within an automation station setup.
