Our story
We started PLC Supply for one reason: when an automation part fails, plants need it replaced now — not in two weeks. Whether it's a PLC, drive, motor or HMI, we work a global surplus network to find the right part fast, and we confirm the lead time before you commit.
Today we source, test and stand behind new, used and refurbished automation hardware, and we repair what others would scrap. From a single obsolete processor to a full panel rebuild, we're here to keep your lines running.
What we stand for
Speed when it counts
A stopped line costs thousands a minute. We quote fast and confirm lead times up front, so you know when the part lands.
Tested & warrantied
Every unit is bench-tested under power and backed by our 1-year warranty.
Hard-to-find specialists
Obsolete and discontinued components are our specialty when the OEM has moved on.
Real expertise
You talk to automation people who know the parts — not a generic call center.
