SIL Controllers

The first TÜV-approved safety system in the world was developed by HIMA. Based on this same world-renowned safety technology HIMA now offers its various systems for a range of requirements  - the foundation for safe AND economic solutions. All of the systems can be integrated easily and comprehensively into any DCS and automation environment on the basis of cross-manufacturer, open communication standards.




With HIMax you improve process profitability. Especially for mid-size and big SIL 3 applications, applications with high performance requirements and plants with requirements of nonstop operation for many years.

HIMax is a flexible platform for large, critical production processes that you can never afford to have go down. HIMax adapts to all I/O-count, response-time and fault-tolerance requirements as well as centralised and distributed applications. HIMax delivers availability for life by enabling uninterrupted system operation throughout your plant’s lifecycle. Hardware and software changes can be performed without system interruption.
