Series 3++

Series 3++ controllers are designed to be the perfect choice for replacing existing Series II, Series 3, and Series 3 Plus single-loop controllers. By packing the state-of-the-art electronics and updated operator interface in the same physical form factor as Series 3 Plus, it provides a seamless upgrade path for the existing systems.

Plug-and-play hardware replacement for minimizing risks and downtime

By keeping the same physical form factor as the existing Series 3 Plus controllers and their backplanes, control system replacement requires no engineering, panel modifications, or wiring changes. Control applications retain the same trusted algorithms and configuration parameters as before – minimizing the risks of upgrade.
