– Product Description
The ABB PM 783F (Order Number: 3BDH000364R0005) is the smallest Freelance AC 700F CPU in ABB’s Freelance 800F DCS family. It is engineered for compact, flexible control applications requiring reliable processing, real-time capabilities, and optimized CPU resource usage. With support for up to 300 I/O points, this CPU is ideal for small to medium-sized automation projects, and offers direct module mounting without backplanes.
This CPU provides advanced multitasking capabilities with eight cyclic and priority-driven tasks and one cyclic task that executes as fast as possible. The controller supports Ethernet communication via Modbus TCP, offers two serial ports for diagnostics and Modbus RTU/ASCII, and features local I/O extension for up to eight modules. The integrated display and function keys allow local diagnostics and operation with locking capability for added security.
