ABB PM825 3BSE010796R1 S800 Processor Module

Product Overview

The ABB PM825 (Part Number: 3BSE010796R1) serves as the central processing unit for the AC 800M controller series within the ABB Advant Master and System 800xA architectures. Designed to resolve critical bottlenecks in complex process automation, this module delivers high-speed deterministic control for demanding industrial applications ranging from power generation to pulp and paper manufacturing. By replacing legacy or failed units with this genuine spare part, facility managers ensure uninterrupted data acquisition, robust logic execution, and seamless integration with existing I/O networks, minimizing unplanned downtime and maintaining operational continuity.

Technical Specifications

Model Code Decomposition

Note: The ABB PM825 utilizes a fixed part number structure (3BSE010796R1) rather than the variable suffix logic found in Bently Nevada or Yokogawa sensor cabling. Consequently, a character-by-character suffix breakdown is not applicable. However, understanding the revision identifier is critical for procurement:

• Base Code (3BSE010796): Identifies the specific hardware architecture of the PM825 processor within the S800 family.

• Revision Indicator (R1): Denotes "Revision 1." In ABB's supply chain, this ensures the module includes the latest hardware updates compatible with current firmware versions. When replacing older units (such as those referenced under legacy ID QF61522981-1), verifying the "R" revision is essential to guarantee backplane compatibility and optimal performance.

Installation Recommendations and Wiring Guidelines

Proper installation of the PM825 processor is vital for system stability. Before insertion, ensure the rack power is isolated to prevent electrical arcing. The module slides into the designated CPU slot on the S800 backplane; apply firm, even pressure until the locking mechanism engages securely.

For connectivity, utilize the specified accessories: install the AF100 plug (3BSC840088R4) for communication bus interfaces and the Power plug (2664177-3) for redundant or primary power feeds. Pay close attention to the onboard lithium battery (Reference: 4943013-6); while pre-installed, verify its seating to ensure non-volatile memory retention during power cycles. Given the unit's classification as Dangerous Goods (UN3091) due to the lithium content, adhere to local safety protocols when handling damaged units. Ensure adequate ventilation around the 225mm depth of the module to maintain thermal limits within the control cabinet.

Frequently Asked Questions (FAQ)

Q: Does the PM825 3BSE010796R1 come with pre-loaded system software? A: No. This unit is supplied as hardware only ("No System Software Program including"). Users must download and configure the appropriate control application and firmware using ABB engineering tools (e.g., Control Builder) after installation.

Q: Is this module compliant with RoHS directives? A: This specific part is exempted from the scope of Directive 2011/65/EU (RoHS) under Article 2(4)(c), (e), (f), and (j), as detailed in the EU Declaration of Conformity (Ref: 3BSE088609) for the ABB Advant Master Process Control System.

Q: What is the replacement history for this part? A: The PM825 (3BSE010796R1) supersedes the legacy product ID QF61522981-1. It is also associated with exchange number EXC3BSE010769R1 for upgrade programs.

Q: How should this item be shipped regarding safety regulations? A: Due to the integrated lithium battery, the package is classified under UN3091, Class 9 (Miscellaneous Dangerous Substances). Shipping must comply with Packing Instruction PI969.
