WebThe Darlington transistor provides high gain ability. The term optocoupler and optoisolator are often used interchangeably, but there is a slight difference between the two. The distinguishing factor is the voltage difference expected between the input and the output. The optocoupler is used to transmit analog or digital information between ... WebMay 6, 2024 · Opto couplers generally cannot provide enough current for standard relays - you need to amplify the output unless you have an opto-darlington, which have that built-in. Opto couplers are signal devices, not power devices. If you look at datasheets you'll see standard photo-transistor output optocouplers are typically 20mA in,
