Always the right solution.

Maximum safety, maximum availability, maximum cost-efficiency: since their launch, the H41q/H51q systems have become THE established standard for safe AND economical solutions in the processing industry.  H41q/H51q systems are ideal for safety-critical applications which require high levels of process availability. Success in these systems is based principally on three factors:

Absolute reliability

H41q/H51q systems are based on what has proven to be the world’s best safety technology. HIMA has installed more than 20,000 solutions and more safety systems than all of its rivals in the global processing industry put together. It’s the quality that has won the day.

Maximum availability

H41q/H51q systems offer the highest level of fault tolerance and therefore process availability. They are proven to be the safety system least likely to fail, and they have a better fault tolerance than any 2oo3/TMR system. And the best thing is that HIQuad technology enables the systems’ fault tolerance to be adjusted individually, which means that cases of redundancy can always be set up specific to the application - making it more economical. Even in single-channel configurations - non-redundant, that is - the systems can be used up to SIL 3 without time limit; defective modules can be swapped during operation.

The safety-related controllers and remote I/O modules of the HIMatrix series were developed especially for distributed and time-critical automation concepts. 

The combination of the world’s fastest safety controller and the fastest safety bus, safeethernet, forms the basis for a range of efficient HIMatrix solutions

The system's performance, compactness and ease-of-assembly enable solutions, which were previously performed using relay technology, to now be set up economically, reliably and much more flexibly using control technology.
Safety-related networking on the basis of safeethernet offers considerable performance and flexibility advantages over solutions using conventional safety controllers and buses.

Combined with our wide range of hardware, this means that our systems can be adapted perfectly to any kind of application - thus creating more efficient solutions.
