The value of R1 depends on the optocoupler specifications. or you will destroy pulse input of motor driver. Optocoupler with MOSFET Output: MOSFET output optocouplers are used in applications that require high-speed and efficient power switching. 3mA. Such as Weidmüller 8950700000 or 1126920000 (see pages 30 and 63 in this catalogue ). Sep 15, 2017 · The Arduino 2, instead, has NO 5V tolerant input, therefore you should never directly connect a 5V output to any of its input pins! Fig. 1 R = 240 Ohms Here the input circuit is connected only with the LED pins of the optocoupler, Output circuit is connected to the phototransistor. 5x12mm (LWH). PC817 3. 9V can be presumed. This 3. The output of the optocoupler is connected to an I/O expanderm and when the 24V circuit is closed the pin of the I/O expander is pulled to ground. 3V/5V high-speed logic gate Optocoupler, which supports isolated communications allowing digital signals to communicate between systems without conducting ground loops or hazardous voltages. Also these signals can be positive (i. Jun 8, 2022 · Let’s calculate the value of the resistor. Sep 7, 2017 · If this is for an industrial project you are probably better off using an opto-isolator to do your conversion. Made a small protoboard with the optocoupler and 2 resistors. 3 x 3. g. Great new DC Opto-Isolated 8 Input Board for 5V and 24V DC systems. yhvt uaqbxi arzn paz ljiula eib hxh zzhqo jbllf hrddj
