HIMA Paul Hildebrandt GmbH

HIQuad safety systems are used wherever there are strict safety regulations to fulfill – without compromising plant availability. The controllers can be used in central and distributed topologies and can draw on a wide range of available I/O modules. So whether you need to protect burners and boilers or pipelines, you still remain on the safe side even when your requirements grow.

HIQuad complies with all relevant standards, from IEC 61508 to EN 50156.

The safety controller may be used for deenergize-to-trip and energize-to-trip applications up to SIL 3.

HIQuad X is a programmable electronic safety system made by HIMA. The flexible and scalable system family is a further development of HIQuad, which has been in use within various applications in the process industries for over 30 years.

Using HIQuad X, you create the perfect foundation for ensuring your plant is up to date in terms of functional safety (IEC 61511) and cybersecurity (IEC 62443). The high-performance controller includes extended reload functions and comprehensive communication options. Additionally, the complete engineering of your HIMA systems is performed by a single platform: SILworX.

Do you already use HIQuad systems? Then you can easily switch to HIQuad X without making changes to I/Os or field wiring. Upgrade times are considerably shorter than before.

Are you responsible for signal technology or safeguarded level crossings in the rail industry – or are you looking for the optimal process safety solution for your pipeline, turbine, or deep-sea application? The highest priority is having a safety system you can rely on to respond as quickly as possible. Your small to medium-sized application is not only networked, it is also time-sensitive.

The compact HIMatrix safety systems can be used as standalone devices or as distributed applications. And they can even be used in level 2 explosion protection zones. They are especially developed for applications with few inputs and outputs per location – and they are extremely cost-effective, as well as extremely powerful.
