Solutions / Legacy Automation Parts Sourcing

Many industrial machines remain in operation long after the automation systems originally installed on them are no longer considered new. Older PLCs, drives, I/O modules, HMIs, and control components may continue to perform reliably, while finding compatible spare parts becomes increasingly important for maintenance teams.

Autelectrical provides sourcing for legacy automation parts used in older industrial equipment and automation systems. The focus is on helping customers locate specific components required to maintain existing machines, replace failed hardware, and keep established systems operating without unnecessary changes.

Legacy automation parts are commonly required when:

• An older machine is still in regular production
• Existing automation hardware needs replacement
• A maintenance team wants to keep original components in stock
• Older PLC or I/O systems remain part of the production equipment
• A drive or control component has been installed for many years
• Equipment modernization is not currently practical
• Replacement parts are needed without changing the existing system

A legacy system does not necessarily mean that the equipment is obsolete. Many older automation systems remain useful and continue to require routine spare-parts support.

Legacy equipment can contain components from several product generations. A machine may use an older PLC platform together with drives, I/O modules, communication hardware, and motor-control components from the same or different manufacturers.

Common legacy sourcing requirements include:

• PLCs and controllers
• I/O modules
• Communication modules
• Variable frequency drives
• HMIs and operator interfaces
• Motor starters and protection devices
• Power supplies
• Relays and control components
• Sensors and other automation hardware

For older equipment, the original model number is especially useful because replacing one component with a newer product is not always a simple substitution.

When submitting a legacy parts request, provide:

• Manufacturer or brand
• Complete original part number
• Product description
• Required quantity
• Machine or equipment information
• Existing system or product family, if known
• Product photos or nameplate information
• Required delivery location

If the original model is known, it should normally be used as the starting point for sourcing.

Some legacy components remain available even though they belong to older product families. In other cases, the original model may have been discontinued and a later replacement may be the only practical option.

A newer model should not be assumed to be a direct substitute simply because it belongs to the same product family. Compatibility can depend on specifications, interfaces, dimensions, firmware, communication requirements, and the existing equipment.

When an original component is discontinued or difficult to locate, our Obsolete & Discontinued Automation Parts service may be more appropriate.

Older automation systems are not limited to a single manufacturer. A production machine may contain components from Rockwell Automation / Allen-Bradley, Siemens, ABB, Schneider Electric, Mitsubishi, Omron, Pro-face, Panasonic, Yaskawa, Sanyo, Delta, JUMO, Bently Nevada, Lenze, Honeywell, Beckhoff, Weinview, B&R, Eaton, Pilz, or ProSoft.

The currently listed online product ranges include Allen-Bradley, Siemens, and ABB. Additional brands and product ranges can be added progressively as the catalog develops.

For older equipment containing components from several manufacturers, Multi-Brand Automation Parts Sourcing can also be used to consolidate the procurement requirement.

How We Handle Legacy Parts Requests

 

 

Identify the Existing Component

We begin with the original manufacturer, model number, description, and available equipment information.

Check Product Information

The requested model is reviewed against available product information to establish its product type and relevant specifications.

Determine Availability

We check whether the requested legacy component can be sourced and determine the practical procurement arrangement.

Review Replacement Possibilities

If the original model is no longer available, a later model or replacement may be considered separately. The suitability of a replacement depends on the actual equipment and application.

Arrange Delivery

Once the requested part and order details are confirmed, delivery arrangements are made according to the customer's requirements and destination.

For legacy automation equipment currently represented in our catalog, the following categories provide useful starting points:

Allen-Bradley

PLC & Controllers

Drives & VFDs

I/O Modules & Communication

Siemens

Industrial PLCs

Industrial Drives

I/O & Communication Modules

ABB

Variable Speed Drive Systems

Control & Interface Modules

Motor Control & Starters

These category pages provide direct access to the relevant product ranges when the manufacturer and general component type are already known.

Keeping an established automation system operating can sometimes be more practical than replacing an entire control system. Having the correct spare components available can also reduce the impact of unexpected failures and planned maintenance.

For equipment that requires hard-to-find or discontinued components, Obsolete & Discontinued Automation Parts provides a more specific sourcing route.

For general maintenance stock and recurring spare-part requirements, MRO Spare Parts Procurement may be relevant.

Send us the original manufacturer, complete part number, quantity, and available equipment information. We can review the requested component and check the available sourcing options.
