F8628X Secure CPU System Communication SIS card

Black Horse F8628X F8652X safety CPU system communication SIS card safety control

system is specially used for dangerous places (such as: petrochemical equipment) interlocking and emergency stop control system.

It and ordinary process control DCS and PLC essential difference is that its function is in the

accident and fault state (including device accident and control system itself failure), so that the

device can stop safely, and in a safe state, so as to avoid the occurrence of disaster, that is, to

avoid injury to the device personnel and the impact on the environment, etc., Therefore, the safety

control system itself must be Fail to Safe, and the reliability of the hardware and software of the system is very high.

In the international safety standard IEC61508, the safety level and safety control system requirements

have detailed provisions. TUV is currently the world’s only safety control system certification body.

Since 1970, HIMA company first introduced the Hima-Planar -System, a fault safety control system certified by TUV, safety control system has a history of 30 years.

Hima’s QMR products h41q and H51q

CPU structure of h41q and H51q is quadruple structure (QMR), and the central processing unit of

the system is composed of four microprocessors. Four processors work at the same time, and every two

microprocessors are installed on a CPU card. There are two CPU cards in the central processing unit, and

one CPU card constitutes the 1oo2d structure.lHima company successfully put 3C company relianttm

compressor controller is integrated into the system and can accept 22ai/6pi/16di; It has 6ao/14do function Pd/ps or h/ps calculation can be completed.
