2. Unboxing & Physical Snapshot

• Model: ABB 500PB101
• Part / Reference: 1MRB200064; published listings commonly associate the complete designation with 1MRB200064/C and order code 1MRB178009R0001.
• Product Type: PROFIBUS communication module / interface.
• System Association: ABB REB500 busbar protection system. Available documentation identifies 500PB101 with the REB500 family.
• Physical dimensions: Not reliably verified from an ABB mechanical drawing located for this exact part. Do not use an estimated dimension for cabinet-fit or freight documentation.
• Estimated net weight: Not reliably verified. Weigh the actual module before issuing a commercial packing list.
• Shipping weight: Gross weight will include the ESD bag, cushioning, carton, and outer packaging.
• What’s in the box: Normally the 500PB101 communication module. Do not assume a PROFIBUS cable, connector, mounting hardware, or documentation is included unless shown on the supplier’s packing list.
• Receiving inspection: Record the complete marking, including 500PB101, 1MRB200064/C, order code, serial number, hardware revision, and date code.

3. Product Introduction

The 500PB101 occupies a communication role within the ABB protection-system architecture rather than acting as a general-purpose PLC communication card. Available product documentation identifies it as a PROFIBUS-DP communication module associated with the REB500 busbar protection system, providing a fieldbus connection between the protection equipment and an external automation or supervisory system.

For spare-parts control, the suffix matters. The commonly published configuration is 1MRB200064/C, while 1MRB178009R0001 appears as the associated order code in product references. Do not collapse these identifiers into a single generic “500PB101” inventory record (that can make revision matching difficult during a protection-system outage).

ABB 1MRB200064/C

The 500PB101 / 1MRB200064/C identification is supported by multiple product references. However, several electrical and mechanical values found online originate from secondary sources rather than an ABB technical datasheet, so they should be treated as verification values, not certified acceptance data.

5. ? Global Compliance & Industry Certifications

For global procurement, separate the module’s product compliance from certification of the complete protection system.

• CE Mark: Verify the physical marking and applicable ABB declaration for the exact hardware revision.
• UL/cUL: Confirm the applicable certification if the REB500 installation is being deployed in North America.
• ATEX / IECEx: Do not assume hazardous-area certification. A PROFIBUS communication module is not automatically suitable for installation within a classified hazardous location.
• Marine approvals: For offshore or marine substations, verify DNV, ABS, or the project-specific certification of the complete protection installation.
• RoHS: Confirm the environmental declaration applicable to the manufacturing revision.

The communication module does not independently establish the certification status of the complete REB500 protection panel. Cabinet construction, power supply, wiring, enclosure, and installation environment all remain relevant.

Verify specific lot certifications with OEM.

6. ? Long-Term Storage & Asset Preservation Guide

Keep the module in its original ESD shielding bag. The PROFIBUS connector and PCB should remain protected from dust, moisture, and unnecessary handling.

Control humidity. Store the spare in a clean, dry warehouse with stable temperature. Avoid moving a cold package directly into a warm, humid environment; allow the sealed package to reach ambient temperature before opening it.

Preserve the revision identity. Record 1MRB200064/C, the order code, serial number, and date code separately. That information becomes important when a legacy REB500 installation requires an exact replacement (especially when several visually similar communication modules are held in stock).

Do not repeatedly insert the spare into a live protection rack simply to verify inventory condition. Use an approved test procedure and suitable test equipment when functional verification is required.

7. Physical Installation Prerequisites

• Mounting: Install the 500PB101 only in its designated ABB protection-system hardware. It should not be treated as a generic standalone PROFIBUS interface.
• Clearance: Follow the applicable REB500 cabinet/rack documentation for module clearance and service access. Do not substitute a generic 50 mm rule.
• Cooling: Keep rack ventilation paths unobstructed. Avoid placing cable bundles directly over ventilation openings.
• Grounding: Follow the REB500 cabinet’s protective-earth and signal-ground arrangement.
• PROFIBUS wiring: Use the approved PROFIBUS cable and connector arrangement for the installation. Maintain proper shielding and termination practices.
• Bus termination: Check the PROFIBUS segment termination before commissioning. An incorrectly terminated segment can produce communication faults that may be incorrectly attributed to the 500PB101.
• ESD: Use a grounded wrist strap when handling the module outside its protective packaging.
• Configuration: Confirm the PROFIBUS station address and system configuration before returning the protection system to service.

Check the bus configuration before replacing hardware. A communication fault does not automatically mean the 500PB101 itself has failed.

8. Buyer’s FAQ

Q1: What HS tariff code should be used for 500PB101?

Do not assign a final HS code solely from 500PB101. The correct classification depends on the module’s confirmed communication function and the importing country’s tariff schedule. Provide the customs broker with the ABB part number, technical description, and supporting documentation.

Q2: What should be shown as the Country of Origin?

Use the actual manufacturer-declared COO of the supplied unit. Do not infer origin from the seller’s location or shipping point. The commercial invoice, packing list, and Certificate of Origin should remain consistent where COO documentation is required.

Q3: How should shipping insurance be calculated?

Use the documented commercial value of the module and retain photographs of the original packaging, ABB identification label, and carton condition before shipment. The final freight weight must be based on the fully packed gross weight, not an assumed module weight.

Q4: Does the 500PB101 have the latest firmware pre-loaded?

Do not assume that it does. The 500PB101 is a communication module, and firmware/hardware revision compatibility should be checked against the installed REB500 configuration. Request the actual hardware revision, firmware information, serial number, and date code from the offered unit before accepting it as a replacement.

For procurement records, retain the complete identification 500PB101 / 1MRB178009R0001 / 1MRB200064/C where those markings are present. This gives the maintenance team a much stronger basis for revision-level matching than the short model number alone.
