Signal Conditioners

Prouldy representing Pepperl+Fuchs in Northern Ireland Ashdale have a range of signal conditioners to protect signal transfer between field devices in safe areas and control systems by galvanic isolation of the loop.

Particularly in case of long transmission paths, signal conditioners avoid compensating currents which may occur from ground loops. Signal conditioners also offer effective protection against electromagnetic disturbance or dangerous over voltages on the signal loops.

Depending on the type, signal conditioners offer additional features like limit switching, transformation from field in standard signals, as well as splitting of signals, which means doubling the input signal.

K-System

These modules are preferred, if both signals from hazardous areas and safe areas are transferred between field devices and the control system.

SC-System

The SC-system offers galvanic isolation in an extremely compact housing and is optimized for application requirements in safe areas.
