    PR Electronics 5202B Ex Pulse Isolator


    PR Electronics 5202B pulse isolator for transmission of signals to the safe area from NAMUR sensors installed in hazardous areas. This signal conditioning isolator measures one or more pulse inputs and provides an identical number of isolated pulse outputs. The PR 5202B uses transformer and optical isolation techniques to provide 3.75 kVac galvanic isolation between the input, output and power terminals. The high level of electrical isolation means that input pulses sensed at the 5202B are not electrically connected to the output pulse. The 5202B has been designed, developed and certified for use in SIL 2 applications according to the requirements of IEC 61508.
    Besides providing isolation, the PR 5202B is a barrier. This means that the module can make an intrinsically safe measurement of contacts and NAMUR sensors mounted in a zone 0/ Division 1 explosion hazard area. The PR 5202B limits the level of energy present at the contact or the NAMUR sensor to a low intrinsically safe level, thereby preventing ignition of a flammable atmosphere around the sensor – even if the sensor or the cable is damaged.

    Features and Benefits


    • 3.75 kVac galvanic isolation between input, output and supply
    • One input signal can be used on two separate outputs
    • A cable error alarm can be detected on a separate output
    • Designed, developed and certified for use in SIL 2 applications
    • Front LED indicates operation status and malfunction
    • DIN rail mounting

    Note

    Not suitable for new installations requiring certification to the latest ATEX standards - see ATEX certificate DEMKO 99ATEX127186 and EU Declaration of Conformity for details
