HIMA F7126 Power supply module

F7126 is a power supply module produced by the German company HIMA, which is a safety control system. It is used to provide a stable and reliable power supply for various modules in HIMA's safety instrumented system (Safety Instrumented System, SIS), such as the central processing unit, I/O module, communication module, etc.

In the HIMA SIS (Safety Instrumented System) architecture, the function of the F7126 power module is:
Provide a stable and controlled power supply for the central processing unit (CPU), I/O acquisition module, communication interface module, etc.
As the power source for the entire security system to start and operate.
Ensure that it will not have any adverse effects on functional safety under circumstances such as electrical power interference and input voltage fluctuations.

F7126 is capable of withstanding extreme industrial site temperature conditions and is highly suitable for applications in harsh environments such as petrochemical, energy, and oil refining. The "8 TE" width of the module refers to the width unit it occupies in the standard rack (TE = module width unit), facilitating standardized rack design and layout.

F7126 is mainly used in conjunction with various security control platforms of HIMA, such as:
The H51q and H41q rack systems (commonly used safety system platforms);
Central processing unit (such as F8650X, etc.);
Various I/O expansion modules and communication modules.
The power module is installed in the power supply slot of the rack.

Number of channels: 16

Input type: digital input, analog input

Output type: digital output, analog output

Safety level: SIL 3

Isolation: optoelectronic isolation

Power supply voltage: 24V DC

The application areas of the F7126 module include modern industrial fields such as electricity, petroleum, mine hoisting, ports, heating, gas, water supply, sewage treatment, metallurgy, papermaking, textile, chemical industry, water conservancy, etc. In addition, it is also suitable for infrastructure fields such as the petrochemical industry, water treatment, and transportation.

F7126 is a component of the HIMA safety instrumented system (PES, Programmable Electronic System), and is typically used in the power modules for the H41q / H51q series of safety controls.
Compatible host cores include:
H51q series security system: High availability redundant system
H41q series security system: Standard security control system
Central processing modules such as:
F8650X (for H51q system) F8652X (for H41q system)

The module system includes:

According to the HIMA system assembly manual (Assembly Kit B5233-1/-2):
A standard H51q rack is usually equipped with 3 F7126 power modules (labeled as PS1, PS2, PS3). These modules correspond to different power supply circuits, and the output of 5 V is connected in parallel to form the core power supply bus of the entire rack.
