Product Description

ABB PM904F 3BDH0001002R0001 AC900F series controller

PM904F 3BDH0001002R0001 is a high-performance controller CPU unit for ABB Freelance AC 900F DCS system, belonging to the high-end model of AC900F controller series, serving as the computing core of the entire control system. The control station is composed of S700 series IO modules, which are widely used in process industries such as water treatment, chemical, energy, and pharmaceuticals to achieve continuous regulation, sequential control, and equipment interlocking.

Product function
  1. Control strategy computation execution: Run the Freelance configuration program to complete PID closed-loop regulation, logic interlocking, timing control, and batch process control.
  2. On site IO data exchange: Collect analog and switch signals from the S700 IO module and issue output commands to control the on-site execution mechanism.
  3. System communication management: Interact data with operation stations, engineer stations, and third-party devices through Ethernet, supporting protocols such as Modbus TCP and IEC 60870-5-104.
  4. Redundant and undisturbed operation: Supports dual CPU redundant architecture, allowing for quick switching in case of main controller failure, ensuring continuous operation of process equipment.
  5. Alarm and event recording: Generate process alarms and sequential events, save fault information, and use it for accident tracing and operation analysis.
  6. Program storage and backup: Equipped with an SD card slot, it supports engineering program backup, firmware upgrade, and data log storage.
