Legacy RTU Upgrades

Extend Legacy RTU Investment

The key to vast savings in time and money lies in our upgrade solution, which allows you to leave the local IO terminations and wiring in place. QEI’s three options will preserve your investment by saving in the cost of installation, wiring, training and spares, but upgrades your technology permitting the latest protocols, communications, IED interfaces, local HMI and NERC/NIST cyber security solutions.

Using RTU specific termination board adapters, the existing wiring terminations remain undisturbed, while the main processor components are replaced. Field labor, engineering and equipment costs are avoided, new modern functionality achieved.
