HIMA F 8621A | F8621A | Coprocessor Module

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.
