What we see from Greenville–Spartanburg
Greenville–Spartanburg is built on automotive assembly and supply, tire manufacturing, advanced textiles and plastics — a region built on continuous-process lines where an HMI or drive failure stops output immediately. That mix decides which controls end up on our bench: automotive, textiles machinery, plastics and tire all depend on operator terminals, drives and power supplies that reach end of life long before the machines they run.
With roughly 3 business days of ground transit each way and 3–5 business days on the bench, most Greenville–Spartanburg customers are back in production well inside the lead time quoted on a replacement unit. When a line is down, overnight shipping plus rush service compresses that further.
We are not a local depot in Greenville–Spartanburg and do not pretend to be — this is a mail-in service run from a single bench lab in Arlington, Texas. What that buys you is a technician who repairs these units every day rather than one who sees one occasionally, and the same 24-month warranty wherever you ship from.

PLC Module Repair in Greenville–Spartanburg — common questions
Do you really serve South Carolina, or do I need a local shop?
We repair units from South Carolina plants every bit as easily as local ones — mail-in is the whole model. You get the same published pricing, the same 24-month warranty, and bench photos/documentation with the work. Most "local" industrial repair quotes end up shipping your unit somewhere anyway; ours just says so up front.
Who pays shipping from South Carolina?
You ship the unit to us with any carrier at your cost (insure it — packing guide provided), and return shipping is selected at checkout: $24.95 ground, $59.95 2-day, or $109.95 overnight, flat nationwide.
My machine in South Carolina is down right now — what's the fastest path?
Overnight the unit to our lab with rush or emergency service selected and it goes to the front of the bench the day it arrives. From South Carolina, overnight shipping plus a 1–2 day rush bench typically beats any replacement lead time by weeks.
