Sensor bar
Currents in AC power systems can be measured with the sensor bar. The measured data
are forwarded to the Data Manager via the RS485 bus and evaluated. The Data Manager
also supplies the 9 V to the sensor bar.
The sensor bar is offered in four variants, with three, six, nine or twelve slots respectively for
the current sensors. The current sensors are located directly on the miniature circuit
breakers and they register the latest current values. The conductors to be measured are run
through the ring-shaped opening in the current sensors to the connections of the miniature
circuit breaker. Up to eight sensor bars can be connected to one Data Manager. With the
sensor bar with twelve current sensors, the currents of up to 96 conductors can be measured
and transferred to the Data Manager. Every sensor bar has a unique Modbus address in the
range between 1 and 247.
