Description

• Model & Brand: ABB PXAH 401, Product ID 3BSE017235R1.
• Product Type: Operator Unit / Millmate Operator Unit 400. ABB’s product data categorizes it under Stressometer 6.0 FSA and PMS140 Strip Width and Position Measurement systems.
• Application: Operator interface for ABB force-measurement and strip-width/position measurement systems, particularly rolling-mill applications.
• Physical Dimensions: Approximately 236 × 161 × 56 mm (W × H × D) based on a supplier listing; verify against the actual enclosure before cabinet or panel cutout work.
• Estimated Shipping Weight: 1.3 kg gross/package weight according to ABB product data. ABB also lists 1.3 kg as the product net weight.
• Gross Volume: 2.3 dm³ according to ABB product data.
• What’s in the Box: PXAH 401 operator unit and original packaging when supplied as new. The required mounting bracket 3BSE017172R1 is separate and should not be assumed to be included.

Product Introduction

The PXAH 401 is an operator-facing component within ABB’s measurement-system architecture. It is associated with the Stressometer 6.0 FSA and PMS140 platforms, where the operator unit provides the local interface for monitoring and controlling measurement functions. ABB identifies the product explicitly as an “Operator unit”, rather than a generic PLC CPU or I/O module.

Physical identity is important with this spare. ABB specifies 3BSE017235R1 as the Product ID and identifies 3BSE017172R1 as the mounting bracket to use with the PXAH 401. The unit is also listed with EXC3BSE017235R1 as an exchange part number (which should not be confused with the primary ordering code).

Core Technical Specifications

ABB PXAH401 3BSE017235R1

The country-of-origin, tariff number, weight, and product classification above are taken from ABB product-detail data reproduced in the available documentation.

Do not use third-party claims describing PXAH401 as an excitation unit or analog input module. Those descriptions conflict with ABB’s product identification. The OEM record identifies PXAH 401 as an Operator Unit.

? Global Compliance & Industry Certifications

For an ABB operator interface used within an industrial measurement system, compliance should be assessed at both the operator-unit level and the complete installed system level.

• CE Mark: Verify the applicable ABB declaration and product revision.
• UL/cUL: Confirm whether the exact unit and its host system carry the required North American certification.
• RoHS: Verify the applicable production revision and ABB environmental documentation.
• ATEX/IECEx: Do not assume hazardous-area certification. The PXAH 401 should not be represented as an ATEX/IECEx device unless the exact product documentation provides that approval.
• Marine approvals: DNV, ABS, or other marine certification must be verified against the exact product/system configuration.

For a panel-mounted operator unit, certification can depend on the enclosure, mounting arrangement, power supply, and surrounding equipment. A CE marking on the complete machine does not automatically establish independent certification for every replacement component.

Verify specific lot certifications with OEM.

? Long-Term Storage & Asset Preservation Guide

1. Protect the operator interface from mechanical impact. The front panel is the most vulnerable part of the assembly. Keep the unit inside its original packaging and use rigid cushioning around the faceplate; do not place heavy cartons on top of it.
2. Keep the electronics dry and ESD-protected. Store the unit in a temperature-stable warehouse with humidity preferably below 60% RH and without condensation. If the original anti-static packaging is present, retain it until installation.
3. Preserve the identification label. Keep the 3BSE017235R1 marking, serial number, and any hardware revision information legible. Do not place warehouse labels directly over the ABB product label (this can become a traceability problem years later).

The ABB product record identifies the unit as a spare part and lists a 1.3 kg gross weight, so inventory records can be reconciled against the actual received package.

Physical Installation Prerequisites

• Verify the required panel/cabinet mounting arrangement before installation. The associated 3BSE017172R1 mounting bracket is separately identified by ABB.
• Confirm the actual panel cutout and enclosure dimensions from the applicable installation documentation before machining the cabinet.
• Maintain adequate clearance behind the operator unit for cable routing, connector engagement, and service access.
• Do not obstruct ventilation openings or cable-entry areas with wiring ducts.
• Bond the metallic cabinet/enclosure correctly to protective earth where required by the system design.
• Use ESD precautions when connecting the operator unit to the associated control/measurement equipment.
• Confirm the PXAH 401 part number and hardware revision against the installed Stressometer 6.0 FSA or PMS140 configuration before replacement.
• Do not assume that a visually similar ABB operator panel is a functional replacement.

Buyer’s FAQ

Q: Which HS tariff code should be used for PXAH401?
ABB product data lists 85389091 as the customs tariff number for 3BSE017235R1. However, the final declaration should still be checked against the importing country’s national tariff schedule and the actual product description.

Q: What Country of Origin should be declared?
ABB’s product data identifies the Country of Origin as Sweden (SE). Use the actual product documentation and supplier COO for the shipment rather than copying origin information from another ABB spare.

Q: Should shipping insurance be purchased?
For international shipment, it is prudent. Although ABB lists a 1.3 kg gross weight, the operator interface contains electronic assemblies and a front-panel interface that can be damaged by impact. Use rigid outer packaging and face protection during transit.

Q: Does PXAH401 include the latest firmware pre-loaded?
Do not assume that a spare operator unit carries the latest application software. The PXAH 401 is an operator unit, and compatibility should be checked against the installed Stressometer/PMS140 system and its software configuration before commissioning. ABB’s product record does not establish a universal “latest firmware” version for every spare unit.
