Navigation light monitor
CS wrote:
I am trying to devise a simple circuit to monitor when a 24v nav lamp has blown. Found this http://www.gammatron.com.au/datashee...0Datasheet.pdf but at AU$54 it is pretty pricey. Should not be to difficult to make up, but I need to know he values of the components. I already have the switch, LED and a resistor to monitor when lamp is on. TVMIA. Put the monitor led in series with the lamp, with two or tree normal diodes accross the led to limit the voltage/current. 20 ohm resistor in series with the led is a good idea. The shunt diodes must be able to carry the lamp current. The read leds need the least voltage. |
