About this circuit
A pulsed coil supply operates the Normally Open Relay while a separate 5 V source feeds its contact load.
Circuit notes
Normally Open Relay Coil-Controlled Load
Application
A pulsed coil supply operates the Normally Open Relay while a separate 5 V source feeds its contact load.
Schematic Organization
The isolated contact supply is on the upper left. The coil pulse source is below it. The relay is centered with its load and measurement to the right.
Expected Behavior
The measured contact node changes state as coil current crosses the relay pickup and dropout thresholds.
Suggested Experiments
Adjust the coil pulse amplitude or pickup threshold and observe when the contact output changes state.
Featured Component
