The very highest of standards.
H41q/H51q
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 18,000 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.
Unique adaptive flexibility and efficiency
H41q/H51q systems are uniquely flexible and are easier and therefore more efficient to adapt to individual application requirements than any other SIL 3 system.
- For any number of I/Os
Compact H41q systems for up to 208 I/Os, modular H51q systems for as many as several thousand I/Os - For any type of I/O
Wide range of I/O cards, analog /digital I/O cards, relay cards, counter and thermo-element cards, cards with integrated Ex-separation - For every availability requirement
Invest only in what you need thanks to scalable redundancy. All of the components can be employed single, redundant or mixed - always SIL 3 - For centralised or distributed applications
Stand-alone or safe networking via safeethernet. - For any DCS integration
Integrated solutions for all leading control systems - solutions that have proven successful thousands of times over
The H41q/H51q systems utilise the same broad range of I/O cards and are both programmed using
ELOP II.
