This CPU module serves as the high-end base unit of the Freelance AC 900F controller family, offering powerful performance and extensive expandability for medium-to-large automation systems. It supports up to 1500 I/O points and integrates four Ethernet interfaces for flexible network architectures and high-speed communication.

The module is equipped with an 800 MHz processor and 48 MB of controller memory, comprising 16 MB battery-buffered SRAM and 32 MB DRAM, ensuring fast execution of control tasks and reliable data retention. Four expansion slots are available for installing additional Communication Interface Modules, allowing adaptation to different fieldbus standards and system topologies.

The operating system is downloadable during software installation, and the unit requires an external 24 V DC power supply. Operation with software version 2019 or later is mandatory. The Display Unit TD 951F and Battery TA 951F are optional accessories and are not included with the base unit.
