DC Current Transducers
Current Sensing Switches are designed to
trip a solid-state contact when there is DC current through
the sensor window. The sensor can be used to interlock two
operations for safety. When one load is energized, the contact
will keep another from also energizing. The power supply
voltage and the controlled circuit voltage can be derived from
a single source or separate sources. The monitored circuit
can be any DC voltage and any amount of current as long as
the conductor will pass through the window. The monitored
circuit is completely isolated from the control circuit. If there
is 3/4 of one amp through the aperture, the output will
change state.
