Maybe my cheap multimeter was messing around, maybe the USB wasn’t giving the 0. There are nine different relays described on the datasheet which differ only in the coil voltage.

Sep 22, 2. As a result, you have to drive the Darlington harder than you think you need to. I’m going to put 8 diodes around the two H bridges thanks for the head up.

My problem is related with my inability to fully saturate the power transistor i recycled from the old board, it’s a NPN transistor 2SC This means you are probably only getting 4V across the relay at best.


This means that the relay is only getting about 4. Thank you for all the replies.

Forward and reverse bias – diode Posted by KevinEamon in forum: Sep 22, 6. Transietor any event, compound transistor connections aren’t magic.

The Pixel 2 is on its way, but consumers are still struggling to get their hands on Pixel 1’s.

Andy aka k 10 In this configuration, the high gain does not carry over to the situation where you want to turn the transistor hard on. Could anyone explain what I am doing wrong? No, create an account now. Sep 22, 5. Digital Tattoos Transixtor The Limits Digital tattoos are an interesting implementation of an new category of “flexible electronics.


Apr 5, 3. No, create an account now. I simulated your motor circuit and and looks like it should work. Nov 4, 2, Yes, my password is: In kn222a2 the gain will be less if you have it backwards, but for a switching application like yours, you may never notice!

The first transistor will saturate according to the data sheet at 0. Posted by mujizat in forum: Hi I tried what you said and it worked. Quote of the day.
