Planar4: The SIL 4 Controller for the Highest Level of Security
Platform for the World's Most Critical Applications
Highly RobustAs Planar4 is hardwired, it is not programmed with software. This makes it extremely resistant to all kinds of errors.
Extremely ResilientThe autonomous system is ideal for automation processes with an extremely high potential risk.
Certified Safety up to SIL 4The Planar4 safety controller meets the requirements stipulated in the highest safety level SIL 4 in accordance with the international standard IEC 61508 Edition 2 (2010).
Full IT SecurityThe controller functions entirely without software. Consequently, successful cyberattacks are not only unlikely – they are physically impossible.
Nothing Is Safer
Wherever there is extremely high potential risk, the Planar4 controller from HIMA ensures maximum safety. It can be used in high-integrity pressure protection systems (HIPPS) for chemical operations and oil refineries. However, with a switching time of just 2 to 10 milliseconds, it can also be used in emergency shutdown systems on oil rigs and in extremely time-critical safety systems and higher-level shutdown systems. Application-specific programming is performed via wiring, such as soldering, Termi-Point, or wire-wrap on the backplane. No software needed.
At the same time, the technology requires very little space, enabling the Planar4 safety controller to come in a 19-inch rack. All modules can be redundantly structured to increase plant availability.
