Industrial-grade I/O for DCS

Single- and Multi-channel I/O

dcs-io-1-1800x600.jpg

Valmet I/O hardware provides a full range of digital and analog interfaces and high-speed controls for Valmet Controllers with single-channel or multi-channel I/O modules. Combining the best of centralized and distributed I/O technologies in a compact format, Valmet's I/O portfolio is simple yet powerful.

Easy to assemble with standard DIN rail installation and front I/O connections

Engineered to withstand extreme environments according to IEC 60721-3-3K3

Hot-swappable components and fully redundant configuration options

I/Os for harsh environments

Valmet I/O hardware is built to withstand the harsh environments of industrial processes while delivering fast control speeds and high-accuracy interfaces. Each unit has conformal coating as standard and an operating temperature up to +70 °C. Optional redundancy on the I/O cabinet level is implemented using dual Fieldbus, power feed, and communication unit per pair. Extensive channel-specific diagnostics, available without additional engineering, ensure you can stay on top of hardware performance. Should an I/O unit need replacing, you change any number of I/O units during operation. Hot swapping is a standard feature of all Valmet I/O models.

Multi-channel I/O

Valmet ACN M80 and M120 series multi-channel I/O units provide robust design and high availability in harsh conditions. ACN M80 is designed for low-voltage and low-current analog/digital applications.

ACN M120 series is designed for high-voltage isolation between the channels and it supports digital interfaces for high DC/AC line voltages without external relays. It also enables high performance in machine condition monitoring and other special features. ACN M120 can also have redundancy on the I/O level when extremely high availability is required.

Both Valmet ACN M80 and M120 I/O units are compatible with Valmet DNA and DNAe Distributed Control Systems.

Single-channel I/O

The single-channel Valmet Signal I/O enhances I/O modularity, allowing you to select and modify each I/O interface independently, without dependencies. This versatile solution includes low and high voltage I/O, condition monitoring I/O, and specialized interface modules, all within a single portfolio.

Signal I/O creates new opportunities for project engineering and collaboration between suppliers. It is compatible with the latest generation of the Valmet DNAe Distributed Control System.
