Signal conditioners 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.

Intrinsic safety barriers are the core of Pepperl+Fuchs' product portfolio. We offer the widest selection of products for protection of electrical signals located in hazardous areas. These intrinsic safety modules combine the energy limiting features of a zener barrier with galvanic isolation. Pepperl+Fuchs offers systems for different applications and mountings. K-System Our most popular intrinsic safety isolated barriers are the flexible DIN rail mounted K-System modules. The K-System intrinsic safety barriers connect easily with our Power Rail assembled in the DIN rail. The use of the Power Rail reduces the wiring by energizing the modules mounted on the DIN rail. H-System The intrinsic safety isolated barriers of the H-System are mounted on termination boards. This innovative product is ideal for applications requiring tight DCS or system integration.

Trip amplifiers change state when the process signal which is being monitored passes one or more adjustable set points, for high or low alarm conditions. Output is via voltage-free relay contacts, so that the process is unaffected by the unit’s operation. We offer an extensive range of analogue process trip amplifiers capable of monitoring all of the standard process signal inputs. Some of the trip amplifiers have a built in transmitter power supply whilst some are for use within existing process loops. Options on a number of the instruments include an upscale drive on loss of input. When linked to the relevant sensor, typical applications for trip amplifiers include tank level control, flow rate control, temperature or acidity control.
