JUMPFLEX® Current Transducers

Current Transducer857-550857-552

The 857-550 Current Transducer detects alternating and direct currents from 0 – 1 A and 0 – 5 A, and converts the input signal into an analog standard signal at the output (e.g., 4 – 20 mA).

The 857-552 Rogowski transducer records RMS values from alternating currents via a Rogowski coil and converts the input signal into a standard analog signal on the output side (e.g. 4 – 20 mA).

Current Transducer2857-550
WAGO's 2857-0550 Current Transducer is used for measuring, isolating and converting AC/DC currents into standard signals in various industries, such as processing, sewage, power technology or machinery, and plant engineering. Transducers protect installations, systems and persons via electrical isolation of measurement signals (immunity to external interferences, such as differential signals or floating grounds, rise in potential) or via overcurrent monitoring. WAGO's transducer is ideal for current measurement and overcurrent detection, while simultaneously isolating field signals to the central control system for further signal processing. Measured values can be optimally displayed and settings can be changed using WAGO's 2857-0900 Display.
