Short description:
The 2857-550 Current Transducer measures AC/DC currents up to 100 A, while
converting the measured current into an analog standard signal at the output.
Features:
• Both digital signal output and relay with changeover contact react to configured
measuring range limits (switching ON/OFF delay and threshold value switch
function configurable with up to two threshold values).
• Clipping capability provides analog signal limitation to output end values.
• Adjustable software filter
• Input/Output response simulation via configuration display
• Safe 3-way isolation with 4 kV test voltage acc. to EN 61140
