Simplex System Controls

From the moment we receive your RFQ, our team examines scope, field requirements, environmental factors, layout efficiency, budget, and timeline before the quote ever goes out. That means fewer surprises and a line-by-line quote you can trust.

Every project also comes with a single point of contact, so your communication with Simplex stays simple and efficient from start to completion.

Not every project needs an off-the-shelf enclosure.
With the ModCenter custom enclosures are built with precision cutouts, giving you an efficient, cost-effective way to keep your build competitive without sacrificing quality.

Whether you're supplying your own schematics or need full turnkey fabrication, our enclosures are engineered to fit your exact application.

Precision meets speed. Our Personal Wiring Assistant (PWA 6000 and PWA 5000) technology helps our wiring shop tackle complex applications faster and cutting standard labor time by up to 30%.

That means greater capacity, tighter precision, and more reliable on-time delivery for our customers without cutting corners.

A panel isn't done when the wiring is finished, it's done when it's proven. Every Simplex panel goes through visual review, point-to-point energized testing, pneumatic air pressure testing, VFD load checks, and PLC I/O verification before it ships.

We document every issue we find and every fix we make, and support Factory Acceptance Testing (FAT) so your startup is clean the first time. No surprises on your production floor.

Labor Day is about more than a long weekend — it's a tribute to the hands and minds that keep American manufacturing running. From our panel designers to our wiring shop, every project that leaves our Elmhurst, IL facility carries the skill and pride of the people who built it.

To our team and everyone in the manufacturing community — thank you for the work you do every day. Happy Labor Day!

Every Simplex panel starts with the same standard: an intuitive, logical layout and organized wiring that's built for reliability, not just for looks.

Our designs meet UL 508A, UL 698A, and UL 1203 standards, along with NEC, NFPA79, and CSA conformance for both standard and hazardous environments. That's engineering you can trust before the panel ever leaves our shop.
