Intrinsically safe limit switch box SRAP series

explosion-proofVDI/VDE 3845

The analog limit switch attachment SRAP is perfect for the position monitoring of quarter turn actuators. The interface, based on VDI/VDE 3845 (NAMUR), allows simple installation on the actuator. • Based on standard VDI/VDE 3845 (NAMUR) • Analog • For monitoring the position of quarter turn actuators • Sensors based on 2D Hall technology • Variants in accordance with EU Explosion Protection Directive (ATEX) Analogue sensor box for greater functionality. The analogue sensor boxmonitors the position of semi-rotaryactuators and reports this back to thecontroller via an analogue 4 … 20 mAoutput signal. Advantages • Simple mounting and commissioning: with teach-in function forflexible adjustment of the zeropoint within a range from 0 – 270° • Everything in view, including froma distance: colour-based indication of the current position of thesemi-rotary actuator • Innovative and intelligent: homingto the actual swivel angle makesoptimum use of the initial range • Sturdy and explosion-proof:a match for even harsh, corrosiveand potentially explosive environments thanks to corrosion-resistantand waterproof metal housing • Insensitive to vibration. Alwayssupplies a stable signal as there isno contact between the shaft andsensor • Quick and easy integration in existing systems thanks to the industrialanalogue output signal • Cost and time savings thanks to thecommon power supply for thesensor box and solenoid valve • Cost-efficient regulation incombination with 5/3-way valvecompared with positioner solution • Festo know-how in automation:concept and solution from a singlesource
