Display
operating states
A Switch Actuator with current detection is predestined for displaying and
recording operating states of electrical loads.
The operating state is detected indirectly via the load current.
If the load current exceeds a threshold, an ON telegram is sent via the bus, if
the value drops below the threshold, an OFF telegram is issued. This
ON/OFF telegram can be received for example by a Universal Concentrator
and displayed on the display panel.
