Is it preferable to put in a diode in reverse before Pin 2 or, is it Pin 3? See a list of all our websites. The relay coil is at the collector of the transistor so it gets nearly 24V across it. If I want to do a complete reversal of the above like isolating a 24v from a hall effect sensor switch going to a parallel port's input pin, can I use this same opto 6N?
Then calculate the value of a suitable base resistor. The foregoing information relates to product sold on, or after, the date shown below. How much current does your relay require, or can you reference a datasheet? Continue to RS India.
Anyhow, can someone guide me how to use this 6N within its limitation. How to wire an Opto 6N It can't be used to directly drive a relay. Most relays need much more current. The problem with low activation is that the relay will be activated when the computer is off or disconnected, although this might be a feature.

North America Canada Mexico.
The cathode of the photo-diode pin 8 must be positive a few volts or also at the positive supply or up to 10V higher. Thermal Pad is needed or not? An ordinary transistor can easily drive the relay. Welcome to our site!
By selecting your country, you will have a much more streamlined shopping experience A current-limiting resistor in series with one of its pins is calculated by using Ohm's Law. Why use a 2N without knowing if it will work?

The relay's coil needs 24VDC at a certain amount of current. You need to know how much current. The Manufacturers reserve the right to change this Information at any time without notice. The product detailed below complies with the specifications published by RS Components. Like I said earlier, the max allowed output voltage for the 6N is only 20V and its minimum output current is only 4.
