ABB PM802F part code 3BDH000002R1 is the foundational CPU controller for AC800F Freelance distributed control system, responsible for logic operation, PID closed-loop control, multi-bus communication and I/O station management, supports dual machine redundant hot backup and modular expansion of communication cards

Product Overview

• PN: PM802F
• Fixed order number: 3BDH000002R1
• Brand: ABB
• Series: Freelance AC800F DCS Distributed Control System
• Type: Field Controller Base CPU Module

• Function: It serves as the core computing and control unit of AC800F system. It downloads user programs via engineering software to complete interlock logic judgment, continuous PID regulation, sequence control and process parameter arithmetic. It communicates with S800 series remote and local I/O modules through internal backplane bus, collects field temperature, pressure, flow, switching state signals, and sends output instructions to on-site execution valves and contactors. It connects with operator stations, engineering stations and upper monitoring platform through Ethernet expansion cards, and can be paired with another PM802F to form 1+1 redundant hot standby, realizing bumpless automatic switching upon main controller failure to avoid production interruption.
