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.
