Scalable, high-performance controllers for DCS
Valmet DNA Controllers
Valmet DNA controllers range from small embedded controllers to large rack controllers. Each modal features a wide range of connectivity and processing capabilities. All Valmet controllers are underscored by a lifecycle philosophy guaranteeing easy transition to new generations. They ensure a dependable platform for all your controls and external connections. These control nodes support the modern ACN I/Os and main industry field buses, such as PROFIBUS, PROFINET, Ethernet/IP, FF and AS-i. Standard links like OPC DA, OPC UA Ethernet and serial links ensure excellent connectivity to third-party systems.
Select from a range of robust controllers to meet your operating conditions and process requirements
Easily connect and extend with Ethernet, fieldbus, PROFIBUS and serial interfaces
Rely on industrial components engineered for long lifecycles and simple maintenance
Modular rail-mounted controllers
ACN MR controller
The high-performance Valmet ACN MR is a multi-functional controller used in centralized, distributed and embedded applications. Valmet ACN MR controllers are also suitable for standalone applications with or without a connection to Valmet DNA.
Its small size and high processing power give the ACN MR great flexibility. The controller can be fitted for small, medium and large applications. In addition to built-in redundancy support, the ACN MR features a removable SD card with all software and parameters for easily swapping to a new node.
Compact industrial controllers
ACN CS controller
The Valmet ACN CS is designed for embedded and standalone applications such as process controls, connectivity, fast machine controls and advanced fuzzy or multivariable controls. Inside the controller’s IP20 enclosure, with optional conformal coating, there are no moving parts for better reliability.
Featuring two extension slots for a variety of PCIe cards to extend interfacing capabilities, the Valmet ACN CS can be easily used in combination with other Valmet DNA controllers, mounted to a 19" rack shelf or panel. The ACN CS supports full one-to-one redundancy, as well as redundant Ethernet and Fieldbus connections.
Large-scale, high-performance controllers
ACN RT controller
Engineered to deliver high performance for centralized applications, the Valmet ACN RT controller is the best solution where very high processing power and multiple fieldbuses are required.
The Valmet ACN RT includes five extension slots for PCIe cards to add interface capacity. In addition to one-to-one redundancy and redundant connectivity, the controller has hot-swappable components including the main fan, CPU fan and air filter.
