The transducers (transmitters) in this line measure DC current without change in polarity. If you need to measure a current with change in polarity (+/-DC), look for the models in "- Current Transducers for instantaneous AC/DC measuring; +/-DC"Click here.
Windowed Current Transducers (Transmitters): Transducers with a window for the current conductor integrated in the encapsulation. All it takes is for this conductor to pass through the window a DC measuring with galvanic isolation. Hall technology.
Current Transducers (Transmitters) with Terminal: Normally used in measuring low current values. In these models, the conductor must be fixated in the transducers terminals. They come with galvanic isolation and hall technology. .
Current Transducers (Transmitters) that use external sensor: Unlike the Windowed e Terminal models, which have current measuring points integrated in the DIN standard board fixation encapsulation itself, these use DC Current Sensors (probes) (HALL Effect Sensor) for measuring. These are used when the current amplitude is high or when measuring points are located remotely (away from the panel).
Multiplexer (Concentrator): In cases where there are several measuring points that need to send data to only one place (equipment), the Multiplexer (Concentrator) receives information from several transducers and concentrates them in only one output.
