Cost effective Availability and Safety
• H41q/H51q - solution needs less
hardware:
high potential to reduce costs.
• H41q/H51q - solution is easy
structured and has a better MTTF:
high reliability.
• The 2out of4/QMR-architecture of
H41q/H51q is insensitive to
"common cause" failure.

Reduction of life cycle cost
• tailor made system configuration
• System AK6 inherently.• Simple and flexible configuration.• Wide range of communication.• Programming with ELOPII-NT.
• Pre-fabricated standard components.• Complete diagnosis of the system.• Offline-simulation with ELOP II-NT.
• tried and tested components.• easy to extend.• all components are hot replaceable.• remote diagnosis.• High fault tolerance, therefore no plant
stop.
