    Description

    ST500Ex-10-0, Intrinsically Safe Universal Isolating Signal Converter, 230VAC

    Properties:
    The ST500Ex isolating signal converters can be used to isolate and convert field signals 0/4...20mA or 0/2...10VDC out of the intrinsically area.
    Isolating signal converter for application in zone 0 or zone 20 (constant explosion risk) with integrated transmitter supply. It allows the direct connection of active 2-wire sensors (4 ... 20mA) and 3-wire sensors in the Ex-area.
    The ST500Ex provides a fully floating isolated transmitter supply.
