ABB AC 900F 3BDH001000R0001 PM 902F CPU Module

Description

The ABB PM 902F (Product ID: 3BDH001000R0001) is a high-performance central processing unit functioning as the medium base controller assembly within the Freelance AC 900F automation architecture. This hardware component executes control programs, tracks high-density process feedback loop networks, and anchors decentralized station communication tasks. Running an 800 MHz internal microprocessor, the PM 902F 3BDH001000R0001 is provisioned with 24 MB of core controller memory, comprising 16 MB of DRAM alongside an 8 MB battery-buffered SRAM partition to guarantee data persistence during power interruptions. The network subsystem features 4 integrated onboard Ethernet interfaces to establish robust plant-level communication rings, while dual modular expansion slots accommodate specialized communication interface modules. Capable of managing approximately 1,500 physical field inputs and outputs depending on specific application sizing, it requires an external 24 VDC power feed and software firmware version 2013 or newer to execute deterministic processing scripts.

Features

• Medium base control unit designed explicitly for the Freelance AC 900F modular automation controller framework.
• High-speed 800 MHz CPU clock engine paired with a 24 MB aggregate controller memory profile.
• High-volume battery-buffered 8 MB SRAM partition to preserve critical process variables and memory tables.
• Four onboard integrated physical RJ45 Ethernet interfaces dedicated to redundancy and field network loops.
• Dual hardware option slots engineered to receive auxiliary plug-in communication interface cards.
• Substantial process execution density enabling scaling up to roughly 1,500 I/O handling points.

Applications

• Distributed process management and regulatory loops across medium-scale manufacturing utilities.
• Centralized supervisory coordination in chemical batch plants, water filtering assets, and thermal processing sectors.
• Multi-bus field network consolidation combining local S800 or S700 drop stations with plant Ethernet rings.

Installation Guidelines

• DIN Rail Installation: Secure the CPU backplane chassis horizontally onto a grounded, standard TS 35 top-hat DIN rail. Tighten all locking tabs to maintain a solid chassis connection against the metal rail.
• Power Supply Polarity: Terminate the external 24 VDC supply cable to the input terminals. Check polarity alignment prior to switching on power to prevent reverse-voltage errors.
• Option Module Fitting: Ensure all input power feeds are fully disconnected from the unit before snapping communication interface modules into slots 1 or 2 to avoid internal bus damage.
• Enclosure Cooling Paths: Maintain a minimal unobstructed physical distance of 50 mm above and underneath the module block to facilitate proper passive convection current airflow inside the local panel housing.
• Operating System Booting: This central module is shipped completely bare of operating software. You must compile and load the respective runtime system image using Freelance Engineering software version 2013 or newer during first-time deployment.
