When a PLC fails unexpectedly, one of the first questions maintenance teams face is whether to purchase a brand-new replacement or choose a refurbished component. The answer depends on several factors, including equipment age, availability, lead time, budget and production requirements.
Both new and refurbished PLC parts have their advantages. Understanding the differences can help businesses make informed purchasing decisions while minimising downtime and protecting their automation investment.
Refurbished PLC parts are previously used automation components that have been professionally inspected, tested and restored to full working condition.
Depending on the supplier, refurbished equipment may undergo:
High-quality refurbished parts are commonly used across manufacturing, mining, water treatment, food processing and many other industrial sectors.
New automation components remain the preferred option when they are readily available and supported by the manufacturer.
Advantages include:
For current product ranges, purchasing new equipment is often the simplest long-term solution.
Refurbished components offer several practical advantages, particularly when maintaining existing automation systems.
Many legacy PLC platforms are no longer manufactured. Refurbished inventory may be the only practical option for replacing discontinued modules.
Waiting several weeks for factory lead times may not be practical during an equipment failure. Refurbished components are often available for immediate dispatch.
Refurbished equipment is typically more cost-effective than purchasing brand-new hardware, helping businesses manage maintenance budgets without compromising system reliability.
Installing a brand-new controller into an ageing automation system may require software upgrades, programming changes or additional engineering work.
Replacing a failed module with an equivalent refurbished unit often allows production to resume much more quickly.
New equipment is generally the better choice when:
Refurbished automation components are often the most practical option when:
Many Australian manufacturers successfully operate legacy PLC systems for years by combining preventive maintenance with access to quality refurbished spare parts.
This is one of the most common questions buyers ask.
The answer largely depends on the supplier.
Professionally refurbished PLC parts should be thoroughly inspected and tested before being supplied. Purchasing from an experienced automation specialist helps ensure the equipment has been verified before installation.
It’s also important to ask about testing procedures, warranty coverage and the condition of the supplied component.
