Figure 2.14 - Output Control with Feedback
Instead of an AC operated relay for feedback status indication, a
current sensor (Model CSM01) can be used, as shown in the next
diagram. The insulated “Live” mains wire goes through the loop of the
current sensor. Do not put both L and N wires through the
sensor. The current sensor senses the AC current flowing in the
mains wire and gives a closed contact status on its output, which is
connected to one of the zones designated for feedback. Compared to
using a relay, this method has the advantage of not having any contact
with the mains voltage. The sensitivity of the current sensor is 100 mA
RMS. If the appliance being controlled takes less than 100 mA, put two
or more turns of the ‘Mains Live’ wire through the current sensor.
