ABB PM902F 3BDH001000R0001 Core Processing & Memory Matrix
Processor Type: PowerQUICC II Pro multi-core processor architecture.
Clock Frequency: 800 MHz
Total Controller Memory: 24 MB broken down into:
8 MB Application RAM: Ultra-fast, battery-buffered Static RAM (SRAM) for data and runtime retention.
16 MB DRAM: Volatile memory for active system management stack operations.
Application Capability: Typically supports configurations managing up to 1,500 Distributed I/O points (depending on code complexity).
Execution Performance: Capable of running 1,000 boolean logic operations in approximately 0.12 ms.
ABB PM902F 3BDH001000R0001 Interfaces & Built-in Connectivity Ports
Onboard Ethernet: 4x Integrated Ethernet channels (IEEE 802.3 standard, auto-negotiating 10/100 Mbit/s lines via standard 8-pole female RJ-45 sockets).
Serial Protocols: 3x RS-232C interfaces (2 general-purpose communication lines for external Modbus bridging, 1 dedicated line for local service/engineering tool connection).
Local Expansion: Built with 2x modular expansion slots on the base chassis to receive optional communication interface modules (such as PROFIBUS DP master cards).
Storage Interface: Natively includes a built-in Secure Digital (SD) card slot for firmware flashing, security keys, and cold system backup restoration.
Supported Protocols: Modbus TCP/RTU, IEC 60870-5-104 grid communication protocol, and system-wide engineering networks.
ABB PM902F 3BDH001000R0001 Long Description

ABB PM902F 3BDH001000R0001 Technical Specifications & Power Options
Power Supply Requirements: Requires an external 24 V DC nominal power feed (operating window tolerates 18 to 30 V DC).
Power Consumption: 24 W typical / 30 W maximum under heavy network loading.
Thermal Dissipation: Maximum heat emission inside closed cabinets is 18 W.
System Redundancy: Natively supports high-availability dual-CPU hot-standby redundancy setups. Switch-over time between master and backup controllers in a fault state is roughly 500 ms.
Remanent Memory Protection: Uses an external lithium battery module (Part Number: TA 951F) for persistent variable preservation during long-term line downs. (Note: The battery module is sold separately).
