H51q-HRS B5233-2 997205233 H41q/H51q System

The H41q/H51q system adopts a Qmr-quadruple modular CPU structure, which means that the central control

unit of the system has four microprocessors. Each two microprocessors are integrated into a CU module,

and the central control unit is composed of two identical CU modules.
The HIQuad system consists mainly of H41q and H51q families, which are based on the same hardware and

software and are the third generation of HIMA PES systems proven by production practices. It can use personal

computers for flexible user configuration, monitoring and event recording. Its excellent performance provides the most secure control guarantee for production control.
The H41q/H51q system of the Black Horse security system adopts a Qmr-quadruple modular CPU

structure, which means that the central control unit of the system has four microprocessors, each of

which is integrated into a CU module, and the central control unit is composed of two identical CU modules.

A CU module constitutes the 1oo2d structure, and HIMA’s 1oo2d structure products can meet AK6/Si3

safety standards. In order to provide maximum availability to users, a dual 1oo2d structure is used, i.e. 2oo4d structure. In

the case of redundant architecture, the high-speed dual RAM interface (DPR) enables two central units to communicate, thus solving the problem of trouble-free repair time constraints. Its fault

tolerance function makes any component in the system fail without affecting the normal operation of the system.
The H41q series of Dark Horse Security Systems is a compact system that consists of a 19-inch rack with

five units in height. The central rack houses all components, including the central unit, interfaces, communication modules,

power and distribution systems, and input and output modules.
HIMA safety redundancy system integrated with 2 CU modules and 2 communication modules

can hold 13 IO cards (up to 208 I/O points)2 power cards (F7130A)
The H51q series of Dark Horse Safety Systems uses a standard modular construction consisting of a

5-cell high 19-inch rack and up to 16 4-cell high 19-inch input/output subracks. The central rack comprises a central unit, interface,

communication module, monitoring module and power module.
