Product Description
The ABB PM 783F (Order No. 3BDH000364R0005) is the smallest Freelance AC 700F CPU module, designed for compact, high-performance control in industrial environments. It supports up to 300 I/O points, and optionally accommodates 8 direct I/O modules plus one Profibus interface module. Equipped with onboard Modbus TCP and two serial interfaces, the PM 783F ensures versatile connectivity.
This CPU is engineered for multi-tasking with eight cyclic tasks and one fast PLC-type task. Such a configuration enables real-time control while maintaining balanced CPU load—ideal for demanding applications. A built-in LCD panel with status indicators and eight function keys allows for clear diagnostics and control at a glance. A controller lock feature enhances security by preventing unauthorized downloads.
