We require reliable operator panels for our transport crawlers, which - in addition to their controlling and monitoring capabilities - also allow for remote maintenance in very diverse environments, from the frosty, arctic tundra to hot desert deployments. We selected G3 HMIs by Red Lion Controls for our applications and are highly satisfied. The application software runs reliably and the simplified remote diagnostics and maintenance won us over. The G3 HMIs are a good recommendation for critical applications using Crimson 3.0 software.
