Selection Guide
Use the following criteria to determine whether the PM876 (3BDH000607R1) is the right choice for your application:
- Current platform: Confirm your DCS is ABB AC800M or AC800HF — the PM876 is not compatible with other ABB families (e.g., Freelance, Advant).
- Processing demand: Choose PM876 for high-speed, multi-loop control; consider PM860/PM861A for lighter loads.
- Redundancy requirement: PM876 supports controller redundancy — verify your backplane and power supply support this configuration.
- Firmware version: Ensure your System 800xA version supports PM876; check ABB compatibility matrix before ordering.
- Upgrade path: If migrating from PM860/PM864A, PM876 offers a direct upgrade with minimal re-engineering.
- Budget vs. performance: For cost-sensitive projects, PM875 (refurbished) may be a viable alternative with similar I/O capacity.
Quality Assurance & Sourcing
- All units sourced through authorized distribution channels or verified surplus inventory
- Each module undergoes functional testing and visual inspection prior to shipment
- Original ABB packaging and documentation preserved where available
- Traceability records maintained for all stock (batch/serial number logging)
- Refurbished units clearly labeled and priced separately from new stock
- 30-day return policy on DOA (Dead on Arrival) units
How to Order
- Confirm your part number: Verify 3BDH000607R1 matches your existing module label or engineering BOM.
- Specify condition: New, refurbished, or surplus — indicate your preference at checkout or via inquiry.
- Request a quote: For bulk orders (>2 units) or urgent requirements, email support@konmask.com for priority pricing.
- Lead time: In-stock units ship within 1–3 business days; out-of-stock items typically 7–21 days depending on sourcing.
- Export compliance: Buyers outside China must confirm import regulations for industrial automation equipment in their jurisdiction.
Replacement & Compatibility FAQ
Q: Can I replace a PM875 with a PM876 directly?
A: In most cases, yes — the PM876 uses the same backplane slot and connector. However, firmware and configuration files must be updated. Consult your ABB system integrator before swapping.
Q: Is the PM876 compatible with older AC800M backplanes?
A: The PM876 is designed for AC800HF but is backward-compatible with most AC800M backplanes. Verify your backplane revision supports the PM876’s power requirements.
Q: Do you supply the PM876 with a warranty?
A: New units carry the manufacturer’s standard warranty. Refurbished units include a 90-day Konmask functional warranty. Contact us for details.
Q: Can the PM876 be used in a redundant controller pair?
A: Yes. The PM876 supports 1:1 controller redundancy when paired with a second PM876 and a compatible redundancy module.
Q: What is the difference between PM876 and PM877?
A: The PM877 is the next-generation successor with enhanced memory, faster processing, and improved cybersecurity features. It is backward-compatible with PM876 configurations in most cases.
