    Description

    TW500, Loop Powered Signal Isolator 0/4-20mA

    • 1, 2 or 3 channels
    • High protection acc. German VDE 0110 group 2
    • High accuracy
    • Low voltage drop
    • 22.5mm case for DIN rail mounting

    Signal isolators TW500 are highly compact devices and offer the cheapest possibility to isolate DC-current signals 0(4) - 20mA without powersupply. The isolation ensures i.e. a safe decoupling of the sensor circuit from the Evaluation circuit. The mutual influence of different measuring circuits by ground or earth potentials is excluded. The integration of up to 3 channels in a 22.5mm housing allows for space-saving assembly.
