Features:
- Foundation unit linking the AC 800F rack backplane with central processing and control functions
- Integration of 32-bit RISC processor with 16 MB battery-buffered RAM and modular expansion capability
- Coordinated operation with AC 800F power supplies, communication modules, and I/O units
The ABB PM803F 3BDH000530R1 Base Unit serves as the central processing unit foundation in an AC 800F rack, providing reliable control logic execution and data retention to all modules within the Freelance system. It continuously processes automation routines through its integrated 32-bit RISC processor while maintaining configuration integrity via 16 MB of battery-buffered RAM, distributing coordination commands through the rack backplane to support steady state operation of all connected modules. The PM803F 3BDH000530R1 requires software version V7.1SP2a or higher, with the operating system loaded during installation rather than pre-installed.
The PM803F 3BDH000530R1 provides essential control functions common to the entire rack, and is a critical component of the automation path, directly affecting the proper, normal operation of the overall control system. One PM803F 3BDH000530R1 Base Unit is required per rack as the primary controller.
For expanded system applications, the AC 800F rack supports additional communication and I/O modules installed alongside the PM803F 3BDH000530R1. In addition to standard single CPU operation, the modular configuration also performs automatic expansion module recognition. The PM803F 3BDH000530R1 executes module integration using the internal backplane circuitry specified in the base unit options. Using this method, the PM803F 3BDH000530R1 continually monitors the status of connected expansion modules. If the system detects that an expansion module is no longer providing stable communication, it will automatically register the fault and place an event in the System Event List.
The PM803F 3BDH000530R1 ABB Base Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
