Company’s Order Placement Process and Guarantees

  • Warranty: 365 days

  • Lead time: 1 week if in-stock; no more than one month at the latest

  • Payment: 50% advance payment; full payment before delivery

  • Express options: FedEx, UPS, DHL

Key Features

  • AC 800M Compatibility – Works within ABB AC 800M controller families and 800xA environments, simplifying upgrades and spares strategies.

  • Dual Ethernet (10/100) – Typically two RJ45 ports for control and network segregation; easy plant-level integration and engineering access.

  • Service/Diagnostic Port – Front service port (commonly RS‑232C) for commissioning, firmware handling, and troubleshooting.

  • S800 I/O Integration – No onboard I/O; pairs with S800 I/O over fieldbus interfaces for scalable, distributed I/O.

  • Redundancy-ready Architecture – In many cases supports controller redundancy when used with the appropriate AC 800M accessories and configuration.

  • CompactFlash/Memory Support – Project storage and backup typically handled via removable media for quick swaps in the field.

  • Time Synchronization – NTP-based time sync commonly available through the system for consistent sequence-of-events timestamps.

Technical Specifications
Brand / Model ABB PM877 – 3BDH000777R1
HS Code 8537.10 (Programmable control equipment/boards, global 6‑digit)
Power Requirements 24 V DC supplied via AC 800M base unit (BU8xx), nominal 24 V DC
Dimensions & Weight Approx. H 186 × W 59 × D 127 mm; ≈ 0.6 kg (typical AC 800M form factor)
Operating Temperature 0 to +55 °C (industrial cabinet environment)
Signal I/O Types No onboard discrete/analog I/O; uses S800 I/O over fieldbus/communication modules
Communication Interfaces 2 × 10/100Base‑T Ethernet (RJ45), 1 × service/maintenance port (commonly RS‑232C); CompactFlash slot
Installation Method Mounted on BU810/BU812/BU814 base units; DIN‑rail cabinet mounting
Application Fields

Plants running ABB 800xA with AC 800M controllers usually adopt the PM877 for controller upgrades, expansions, or spares stocking. It’s well-suited for:

  • Power generation and CHP units (boiler/turbine auxiliary control)

  • Water & wastewater (filtration, pumping, disinfection trains)

  • Chemicals and specialty chemicals (continuous and batch units)

  • Pulp & paper (stock prep, paper machine auxiliaries)

  • Metals and mining (material handling, utilities, drives coordination)

A maintenance supervisor recently told us the main benefit was “keeping the same toolchain and I/O footprint,” which meant no retraining and minimal documentation changes after the swap.

Advantages & Value

  • Reliability – Proven AC 800M platform; typically stable even in mixed legacy/modern networks.

  • Compatibility – Works with S800 I/O and common AC 800M communication interfaces like CI854A (PROFIBUS DP) or CI871 (EtherNet/IP), which keeps spare parts common.

  • Lifecycle Savings – Extends your 800xA investment; avoids costly rip-and-replace migration.

  • Serviceability – Removable media for backups; straightforward swap procedures reduce MTTR.

  • Support – We can pre-load firmware and basic configuration so commissioning teams can plug in and verify quickly.

Installation & Maintenance

  • Cabinet & Mounting – Install on BU810/BU812/BU814 base units on DIN rail inside a clean, ventilated cabinet; allow airflow around the module.

  • Power & Grounding – Feed regulated 24 V DC to the base unit; maintain proper protective earth. Keep network and I/O cabling separated from high-voltage wiring.

  • Networking – Use industrial Cat5e/Cat6 for the dual Ethernet ports; enable NTP time sync on the plant network for consistent event logs.

  • Safety & ESD – Handle with ESD protection; de-energize the base unit before insertion/removal.

  • Routine Care – Periodically back up the application to the memory card, check status LEDs/diagnostics, remove dust with dry air, and validate firmware updates in a staging area before applying.

  • RTC Battery – If used with a real-time clock backup, replace the battery at the recommended interval to maintain timestamps during power loss.

Quality & Certifications

  • Certifications: CE; UL/cUL (typical for AC 800M family); RoHS compliant

  • Manufacturer Quality: Produced under ISO 9001 quality systems

  • Warranty: 365 days (our supply policy)

Related and Supporting Components

  • Base Units: BU810K02, BU812, BU814 (mounting/power interface for AC 800M CPUs)

  • Communication Interfaces: CI854A (PROFIBUS DP), CI871 (EtherNet/IP), CI853 (SattBus) depending on installed networks

  • S800 I/O: DI801/DO801/AI801/AO801 and related modules for discrete/analog expansion

  • Power & Accessories: CompactFlash card for application storage; suitable 24 V DC industrial power supply and proper cabinet grounding hardware

If you’re replacing an older AC 800M CPU or preparing a cold spare, sharing your current firmware level and network topology typically helps us prep the PM877 so it deploys quicker on site.
