Hi everyone,
I am doing a project where I need to use an optocoupler as a switching device. I ll need to input a 5 V pulse that will close the circuit and output 24 VDC onto a terminal of a certain device. A 0 V will open the circuit.
I am planning to use HCPL-3020 0.2A output current gate drive optocoupler. This is the first time I am dealing with an optocoupler so bear with me if I ask too many stupid questions.
I ll be sending 5 V pulses from a DAQ (data acquisition) device. The idea is to control a frequency controller that requires 24V DC, max. 140mA to activate. I want too be able to use the DAQ along with the optocoupler to switch this Freq. controller ON and OFF.
Q.1 Is the above mentioned optocoupler suited for this ?
Q.2 Any help regarding a basic circuitry to get me started will be greatly appreciated.
I know I am asking a lot but my project depends on this bit of information. I am a computer engineer and have very limited knowledge about electronics.
Cheers,
