Optoisolators are devices that use a light-emitting diode (LED) to communicate with a photodetector, such as a phototransistor or photovoltaic cell, across an isolation barrier to provide electrical isolation between two circuits. This isolation prevents hazardous spikes of voltage from damaging sensitive inputs or outputs of circuit boards or components. The 4N29SM is a type of optoisolator that is specifically designed for transistor photovoltaic output applications.
The 4N29SM is a compact, low-cost, embedded module that is particularly useful for transferring low-power output signals across the isolation barrier. It provides superior isolation protection between and within a variety of circuits. This is because it is designed with a three-stage opto-coupler consisting of a LED, a phototransistor, and a photovoltaic cell.
The 4N29SM works by having the LED emit light into the phototransistor. This transforms the electrical energy from the LED into an electrical signal that can be used to control the photovoltaic cell. The photovoltaic cell generates an electrical current proportional to the light present. When the current generated by the photovoltaic cell reaches a certain value, it is sent through the transistor and across the isolator barrier to the other circuit. The voltage of this current is proportional to the light output from the LED, and it is the output signal of the 4N29SM.
The 4N29SM is ideal for applications that require isolation between two circuits or for transferring low-power signals across an isolator. It is also ideal for systems where reliability is important due to its low-power output and superior isolation protection. Additionally, it is capable of maintaining a constant current output over a wide range of input voltages, so it is suitable for use in systems where stability is important.
The 4N29SM is widely used for a variety of applications, such as in solid-state relays, power conversion systems, automation controllers, and in military systems. It is also used to transfer analog output signals, such as voltage and current, across an isolation barrier.
The 4N29SM is a reliable device that is easy to use and relatively inexpensive. It is designed to provide superior isolation between two circuits while still allowing low-level signals to be transferred. It is an ideal choice for any application where a lower-cost, reliable optoisolator is needed.
