ABB PM902F 3BDH001000R0001
Product System Introduction
The ABB PM902F 3BDH001000R0001 is a high-performance standard CPU module serving as the core processing unit of the ABB Freelance AC900F distributed control system. As a key mainstream controller in the Freelance DCS product lineup, it acts as the central brain for entire system operation, responsible for global logic scheduling, data calculation and equipment linkage management. This module adopts industrial real-time operating architecture and high-grade hardware configuration, supporting redundant deployment to achieve fault-tolerant system operation. It can be perfectly matched with AC900F series I/O modules, communication cards, power supplies and baseplates, supporting up to 10 direct S700 I/O modules and massive remote I/O access. Widely deployed in power plants, chemical processing, water treatment, building materials and process manufacturing industries, it provides stable and reliable core computing support for medium and large-scale continuous industrial production control systems, and is also a mainstream replacement part for old Freelance system maintenance and upgrades.
Product Functions
This advanced industrial CPU module integrates powerful real-time computing, program execution and system management functions, covering all core control requirements of process automation. Equipped with an 800MHz high-speed processor, 16MB DRAM, 24MB system memory and 8MB battery-buffered SRAM, it efficiently executes complex control programs including continuous PID regulation, discrete sequence control, safety interlock logic and batch production scheduling. The built-in battery-buffered memory ensures complete preservation of critical process data and operating variables during sudden power failures, avoiding data loss and production parameter deviation. With four independent 100Mbps Ethernet ports and dual serial interfaces, it supports stable data interaction with upper monitoring systems, HMI terminals and third-party automation devices, enabling high-speed transmission of field I/O signals and control commands. Additionally, it reserves two expansion slots for additional communication modules, supports flexible protocol expansion, and integrates comprehensive system self-diagnosis, operation log recording and fault alarm functions, facilitating daily program debugging, system maintenance and rapid on-site troubleshooting.

Product Features
ABB PM902F 3BDH001000R0001 delivers outstanding processing performance, ultra-high operational stability and excellent industrial adaptability, fully meeting the stringent long-term operation standards of industrial DCS systems. The high-frequency processor and large-capacity memory configuration ensure fast program response and smooth multi-task parallel operation, effectively reducing system control delay and improving process regulation accuracy. It supports standard 24VDC industrial power supply with only 1A rated current consumption and 18W maximum power dissipation, featuring low power consumption and energy-saving operation. The redundant operating support effectively eliminates single-point system failure risks, greatly enhancing production continuity and system safety. Adopting rugged industrial modular design and electromagnetic shielding technology, it operates stably within -20°C to +60°C wide temperature range, resisting on-site high temperature, humidity, vibration and electromagnetic interference. The expandable communication slot design enables flexible function upgrading, adapting to diverse industrial networking demands. With excellent backward compatibility, it perfectly matches new and old versions of Freelance AC900F systems, ideal for new project construction, old system renovation and spare part replacement, featuring long service life and low failure rate.
