Description
Product Overview
The ABB PXAH401 3BSE017235R1 is an operator unit used in ABB force measurement applications. ABB’s product information identifies it as the PXAH 401 Operator Unit 400 and lists it under the Stressometer 6.0 FSA and PMS140 product categories. It is associated with industrial measurement systems used in metal processing, where operators need access to measurement information and system operating functions. The exact functions available on a particular installation depend on the connected measurement equipment and its configuration.
In rolling-mill and strip-processing environments, force, width, and position measurement systems provide information used to monitor material behavior and maintain process control. The PXAH401 serves as an operator-facing component in the relevant ABB system configuration; it should not be mistaken for an independent PLC CPU or a standalone measurement transmitter. Its suitability depends on the installed system family, compatible electronics, configuration, and physical mounting arrangement. ABB lists the dedicated mounting bracket under part number 3BSE017172R1, which should be checked when planning a replacement.
For maintenance engineers, replacing an operator unit involves more than matching the front-panel appearance. Verify the complete part number, inspect the connector arrangement and hardware markings, and establish whether the existing installation belongs to a Stressometer 6.0 FSA, PMS140, or related Millmate configuration. Do not assume that every application listed in a supplier catalog uses identical wiring or configuration settings. If the unit is being sourced from surplus or refurbished inventory, request photographs of the actual hardware and evidence of functional testing.
The PXAH401’s documented net weight is 1.3 kg. ABB’s published product data does not establish every electrical, environmental, and interface specification needed for installation, so those values should be taken from the correct system manual rather than inferred from a similar operator unit. Before returning a replacement to service, follow the plant’s approved commissioning procedure and confirm that the operator interface communicates correctly with the intended measurement system.
Product Introduction
The ABB PXAH401, ordering number 3BSE017235R1, is a dedicated operator unit for compatible ABB force measurement equipment. Its documented product categories include Stressometer 6.0 FSA and PMS140. These references provide a useful starting point for identifying the correct spare, particularly in plants maintaining older rolling-mill instrumentation. The product should be specified by its complete part number rather than by the abbreviated PXAH401 designation alone.
When preparing a purchase order, confirm the system model, original unit markings, mounting arrangement, and required accessories. ABB identifies mounting bracket 3BSE017172R1 as a related item. Ask the supplier to state whether the unit is new, unused surplus, or refurbished, and request the actual product label and applicable test records. After installation, verify the interface, measurement display, alarms, and operator functions required by the installed system. Electrical ratings and communication details should be confirmed from the relevant ABB documentation before connecting the unit.
