The 2857 series current signal converter from Wago measures AC/DC currents up to 100 A while converting the measured current to a standard analog signal at the output. It provides a digital signal output and a relay with changeover contact. Features include a limiting function that allows restriction of standard analog signals to upper range values, an adjustable software filter, input/output response simulation via configuration display, and safe 3-pole isolation with a 4 kV test voltage according to EN 61140.
