ABB Advant Controller 110/160

Stop the clock on industrial downtime. When your core control "brain" fails, the manufacturer’s lead times can be a death sentence for your production. Moore Automated acts as the "extra-grade emergency warehouse" for industrial giants, maintaining a massive inventory of hard-to-find and discontinued ABB AC110 and AC160 modules. Whether you are supporting a 20-year-old power plant or a critical refinery, we provide the supply options with availability and dispatch timing confirmed in writing and a one-year independent warranty.

1. Application Scenarios: Where do AC110 and AC160 fit?

• Safety-Critical & Nuclear Applications: If your facility requires a system with a proven "pedigree" for Nuclear Power Plant (NPP) protection or high-integrity turbine control (gas, steam, or hydro), the AC160 is the industry standard. It is the core of the Westinghouse Common Q™ platform, specifically designed for high-reliability environments.
• High-Demand Multiprocessing: For complex logic that requires massive computational power, the AC160 supports up to six PM646A or PM665 processors working in parallel within a single subrack.
• Standard Industrial Logic: For general plant automation where cost-efficiency is a priority but reliability cannot be sacrificed, the AC110 remains a robust choice for medium-scale tasks.

2. Processor Selection: Confirm the Installed Requirements

• The PM645 Failure Path: If your existing PM645A or PM645C modules have failed, these are no longer available from the manufacturer. The PM645B is a potential sourcing option only after the complete part numbers, revisions and installed configuration have been checked against applicable manufacturer documentation.
• Maximum Performance: For a processor change, first confirm the controller, firmware, application load and interfaces. Review the PM665. A documented engineering review must approve any proposed upgrade before ordering.
• Safety-related applications: Confirm the exact module, approved system configuration and applicable manufacturer and site requirements. A supplier warranty is not a safety certification or approval to replace a component in a safety system.

3. Communication Interface: Twisted Pair vs. Coaxial

Selecting the right interface depends on your physical bus media:

• For Coaxial Networks: Use the CI626 (AC110) or CI630 (AC160).
• For Twisted Pair Networks: Use the CI627 (AC110) or CI631 (AC160).
• Distance Constraint: Note that these systems generally support a maximum bus length of 2000 meters. While some extensions exist, the AC110 and AC160 are primarily optimized for this distance.

This is general series information, not replacement approval. Confirm the exact ordering code, revisions and applicable manufacturer specifications with your engineering team before purchase.

5. Purchasing Suggestions: Why Moore Automated?

• Avoid Forced "Rip-and-Replace" Upgrades: ABB has moved the AC110/160 to the "Classic" and "Limited" lifecycle phases, meaning the support of the original factory is often restricted or tied to expensive system-wide upgrades to 800xA. The suitability of continued operation or migration requires a documented engineering and lifecycle review; sourcing a spare does not guarantee an additional service life.
• Exact Hardware Matches: We stock critical communication interfaces like the CI626 (for coaxial media) and CI627/CI631 (for twisted pair), with suitability for the installed AF100 network subject to your engineering team’s review.
• Ready-to-Ship Replacements: Send the full part numbers, revisions and system details when considering PM645B for an existing PM645A or PM645C. Compatibility and dispatch timing must be confirmed before ordering.

Plan a Documented Replacement

Send the exact ABB Advant Controller 110 or 160 part number, revision, installed-system information and required delivery date. We will review new and unused supply options and confirm product condition, availability and dispatch timing in writing. Your engineering team must approve suitability before ordering.

Each supplied item receives a pre-shipment inspection. Functional testing depends on the available equipment and agreed scope for the item. Products include a 12-month Moore Automated warranty from shipment. Ask for the applicable inspection record and review our Warranty Policy before ordering.

Frequently Asked Questions

Will a replacement work with my existing AC110 or AC160 configuration?

Compatibility must be checked for the exact controller, hardware revision, installed firmware and project environment. Provide the existing module label and system information. Your engineering team should confirm configuration, licensing and commissioning requirements before approving the replacement.

Does a FAULT indication prove that a module must be replaced?

No. A fault indication is a starting point for diagnosis, not a complete diagnosis. Record the exact module, indication pattern and available diagnostic messages. Qualified personnel should follow the applicable manufacturer procedure before deciding which component requires replacement.

What condition are the AC110 and AC160 parts you supply?

Moore Automated supplies only new and unused industrial automation parts, including new surplus. We do not sell used, dismantled or refurbished parts. Original packaging, seals, date codes and included accessories may vary and will be described in the written quotation.

Can PM645B replace my PM645A or PM645C?

Do not treat the model names alone as replacement approval. Send the complete existing and proposed part numbers, revisions and system details. The replacement must be checked against the applicable manufacturer documentation and approved for your installed configuration before ordering.

What should I check before selecting a higher-performance processor?

Define the installed controller, firmware, application load and required interfaces first. A processor change needs a documented engineering review of system compatibility and commissioning requirements. We can then review availability for the approved part number.
