Description 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. Typical Applications. Safety functions for de-energize to trip energize to trip. Continuous and batch plants. Burner and boiler protection. Oil and gas pipelines etc. HIQuad X System Benefits .
