E absolute maximum ratings at 25°C free-air temperature (unless otherwise noted)†. Input-to-output peak voltage (8-ms half sine wave): 4N kV. standard single channel phototransistor couplers. These families include the 4N35, 4N36, 4N37, 4N38 couplers. Each optocoupler consists of. Cosmo 4n35 optoisolator for DC voltage measuring. Hi all, I’ve encountered a problem. I’ve tried to set the input current to the opto by using 5V.

I think I will just let the ADC port get the signals directly from the contacts.
HOT NEW IC 4N35 F4N35 4N 35 COSMO SOP6
How do you get an MCU design to market quickly? Thanks Post added at Cosmo 4n35 optoisolator for DC voltage measuring.
If that doesn’t make sense then maybe it cos,o help to post your circuit, Keith. I guess there’s no substitute for the hcpl eh? But it is quite expensive at 11usd per unit. Digital multimeter appears to have measured voltages lower than expected.
Opto 4n35 for voltage sensing?
HOT IC 4N35 F4N35 4N 35 COSMO DIP6
Equating complex number interms of the other 6. Distorted Sine output from Transformer 8. So you circuit is working correctly – although maybe xosmo how you want it to. Cosmo 4n35 optoisolator for DC voltage measuring How do I improvised it to be directly proportional, Keith? I’ve tried to set the input current to the opto by using 5V and ohm resistor, resulting less than 10mA input current.
Cosmo 4n35 optoisolator for DC voltage measuring I can only guess at your circuit. Cosmo 4n35 optoisolator for DC voltage measuring Hi all, I’ve encountered a problem. Cosmo 4n35 optoisolator for DC voltage measuring Hurm What is the function of TR1 in this circuit 3. Part and Inventory Search. Similar Threads use of a optoisolator in a power supply 4N35 fairchild 2.
Choosing IC with EN signal 2. A simple timer can convert the voltage to frequency is a cheaper alternate. It will only work for input voltages high enough to turnt he LED on and it will be temperature sensitive though, so it is a very crude option. Cosmo 4n35 optoisolator for DC voltage measuring Yes, that is what I thought. Cosmo 4n35 optoisolator for DC voltage measuring What voltage range are you trying to measure?
Looking for a sensor for measuring V AC 9.

Cosmo 4n35 optoisolator for DC voltage measuring What you have will be inversely proportional which would be fine – it can be sorted out in software – except that if you were hoping to measure input voltage in that way you will fail because cosom the non-linear relationship between the LED current and voltage. Dec 248: Originally Posted by nandhu If you feel 8 timers and 4n35’s too much, you can use one timer and an opto and multiplex the input of timer.
