Make the whole
line talk.
Relay designs, builds and commissions control systems, robotic cells and plant data for manufacturers across the Midwest. PLC and HMI programming, panel build, robot integration, and the dashboards that show a line what it is doing.

UL 508A panel shop
Panels built in the building, drawings and bills of material supplied.
Commissioned to a plan
Signed off against a written test plan you approved before we built.
Code written to be read
Commented programs and as-built drawings the next engineer can follow.
Engineers on the line
The engineer who commissioned your cell answers the support line.
Four layers. One integrator.
Pick a layer. Each describes what we build there and who to talk to.

Logic the operator can trust.
PLC programs, safety circuits and HMI screens written so the next engineer can read them. Panels built in-house to UL 508A.
Discuss control systems
Fourteen machines, three dashboards, downtime causes visible by shift within a month.
See the cellsDefine it. Prove it. Put it to work.
Discovery & specification
Document the current process, interfaces and constraints. Agree on the problem before selecting the solution.
Engineering & validation
Control architecture, safety review, simulation where it pays. Drawings and a test plan you sign before we build.
Build & commission
Panels built in-house, code tested on the bench, then commissioned on your floor against the plan.
Handover & support
As-built drawings, commented code, operator training, and the support line the commissioning engineer answers.
Recent cells, and what they changed.
Sample projects for this fictional integrator. Open one for scope and result.
Eighteen engineers, one support line.
Relay is eighteen controls and robotics engineers in Grand Rapids, with a UL 508A panel shop in the building. We work across Michigan, Ohio and Indiana, mostly in packaging, automotive tier suppliers and food plants.
