Modular rail-mounted controllers
ACN MRN controller
The high-performance Valmet ACN MRN is a multi-functional controller for centralized, distributed, and embedded applications. Valmet ACN MRN controllers are also suitable for standalone applications with or without a connection to Valmet DNA and Valmet DNAe.
Compact size and high processing power give the ACN MRN great flexibility. The controller can be fitted for small, medium, and large applications. In addition to built-in redundancy support, the ACN MRN features a removable SD card with all software and parameters for easily swapping to a new node.
Modular rail-mounted controllers
SCN controller
The high-performance modular Valmet Smart Control node (SCN) is a multi-functional controller for centralized, distributed, and embedded applications. Modular Valmet SCN controllers are also suitable for standalone applications with or without a connection to Valmet DNAe.
Modularity and integrated features give the SCN great scalability. The controller can be fitted for small, medium, and large applications with excellent distribution support. In addition to built-in redundancy support for the automation network, interfaces, process controller, and power feed, the SCN 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.
