HIMA HIQuad X A New Dimension of Performance for Your Safety System

HIQuad X is a programmable electronic safety system made by HIMA. The flexible and scalable

system family is a further development of HIQuad, which has been in use within various applications

in the process industries for over 30 years.

The modernization combines tried-and-tested HIQuad I/O technology with the high-availability and

high-performance HIMax system technology. HIQuad X is programmable with SILworX, the HIMA

engineering tool. HIQuad X safety systems are installed if restrictive safety requirements must be

fulfilled – without any compromises on system availability. The safety PLC can be used on a centralized

as well as decentralized basis. A huge variety of I/O modules can be used – including intrinsically

safe SIL 3 modules.
