Designed to provide maximum safety, HIQuad solutions are an ideal choice for small and mid-size safety-critical applications requiring high levels of process availability. H41q/H51q systems provide proven performance.
Absolute reliability
HIQuad solutions are proven over decades of use in hundreds of process industry facilities. They are the industry standard for reliable and cost-effective solutions.
Scalable availability
HIQuad solutions are available with different combinations of scalable availability at the I/O and CPU level, allowing a precise match for your budget and technical needs while providing maximum safety. Even in a non-redundant, single-channel configuration, HIQuad can be used up to SIL 3 without any limits.
Flexibility
H41q/H51q systems are extremely fl exible and can be easily adapted to your application requirements.
- For small and mid-size 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: Thanks to scalable redundancy, you invest only in what you need.
- For centralised and distributed applications: Stand-alone or safe networking via safeethernet
- For any DCS integration: Integrated solutions for all leading control systems
