Intrinsic Safety Isolated Barriers from Pepperl+Fuchs - K-System

1 min read

Intrinsic safety barriers from Pepperl+Fuchs limit the energy that is supplied to a circuit and protect hazardous areas from excess energy. By limiting energy to a safe level, intrinsically safe circuits prevent the ignition of potentially explosive atmospheres.

In addition to their explosion protection function, isolated barriers offer galvanic isolation to protect measurement and control circuits from signal distortion and dangerous surges. These interface modules also convert, standardize, and split measurement and control signals.

K-System

■The most comprehensive interface portfolio for

hazardous areas

■ The system makes it possible to use modules for both

hazardous and non-hazardous areas on the same rail

■ Isolator modules are mounted on the Power Rail used for

the power supply and collective error messages

■ Many modules are available that meet the requirements

of SIL according to IEC61508 (SIL 2 and SIL 3)

■ SIL 3 for all signal types

■ Packing density of up to 6 mm per channel for all signal

types, further space savings of up to 50 % possible with the

K-DUCT profile rail

■ Can be used at ambient temperatures between

–40 °C and +70 °C (–40 °F and 158 °F)
