Intrinsically safe barriers Pepperl+Fuchs HiC2441, Z765.F and others.

K-System intrinsic safety barriers are a wide range of devices. They provide a high level of protection for electrical signals that enter explosive areas of the circuit.
Key Features of K-System Barriers:

• Galvanic isolation. Prevents signal distortion and dangerous overvoltages.
• Snap on the mounting DIN rail. The power supply circuits to the modules can be connected via separate terminals or via a power Rail.
• Removable terminal blocks. They simplify the connection and assembly of the control cabinet.
• Controls and controls on the front plane. The barriers are convenient to use and easy to maintain.

The intrinsically safe barriers of the H-System series include isolation barriers for signals from or into potentially explosive areas with galvanic isolation, which are mounted on the terminal load board. The terminal load boards are mounted in the control cabinet on a 35 mm DIN rail. The signal circuit between the field and control side is closed by connecting the module.

Zener barriers are an explosion protection device that limits the amount of energy transferred to a hazardous area to a safe level at which it is impossible to ignite an explosive environment. The principle of operation of the Zener barrier is based on the use of zener diodes (Zener diodes), which limit the voltage passing through the barrier to a safe level.
