It utilizes a current transformer, single transistor amplifier, voltage doubler detector, robust relay and capacitor limited AC power source. Schematic of the AC Relay Switch Circuit. Current transformer. The current transformer came out of my junk box - it has unknown specifications other than its turns ratio (1000:1) that I measured.

During the current sensing process, the current is measured by measuring the magnetic field. The output voltage is very low and needs to be amplified to a useful value by using a high gain amplifier with very low noise. Apart from amplifier circuit Hall Effect sensor requires additional circuitry as it is a linear transducer. 1. Activity points. 69. I have been digging through various forums and internet articles searching for a current sensing relay circuit that will activate a low voltage relay when the circuit senses a 120v machine drawing 5 or more amps of power. I have hand drawn a schematic and is attached. My desire is to activate a low voltage circuit by ... Ways to measure current: 1- Indirect method: such as current transformers (in the figure) and Hall effect sensors, which relies on Faraday's law of induction to sense current in a circuit and convert it to a proportional voltage. These methods are suitable more for high current systems. 2- Direct method: which relies on Ohm's law which states that V = I x R. Source: morningstarcorp.com. Size: 72.00 KB. Dimension: 654 x 493.

Introduction. Time relay refers to a kind of relay whose output circuit needs to make an obvious change (or contact action) after adding (or removing) the input action signal in a specified and accurate time. It is an electrical component used in a circuit with a lower voltage or a smaller current to switch on or off a circuit with a higher voltage and larger current.

Current Actuated Relay Driver

It's working and outputs a 4.6v signal on the AC control wire when you press the AC button on the climate control. The current on the signal wire is only about 4-5 mA. The original engine computer looks for that signal and then raises the engine idle and grounds the relay for the AC compressors magnetic clutch. Simple.
