Optoisolators, also known as optically coupled isolators or photocouplers, are used in electronic design to isolate or “float” two circuits from each other and improve noise immunity. Among the various types of optoisolators, Logic Output optoisolators are those optoisolators that have transistor outputs, and one of them is the PS9324L2-V-E3-AX.

The PS9324L2-V-E3-AX is a logic output optoisolator typically used in the isolation, detection and control of AC and DC currents. It is a single-channel, optically isolated logic output module for galvanic isolation of signal and 3.3V/5V selectable level circuits. It consists of an InfraRed LED on one side and a phototransistor on the other side, both connected in a unique way and placed in a 6-pin plastic package.

In terms of application fields, the PS9324L2-V-E3-AX optoisolator can be used in any proximity detection or ambient light sensing circuits. It can also be used to isolate signals in communication systems, where it is important to reduce electro-magnetic interference (EMI) between connected devices. Moreover, this particular optoisolator can be found in several motor control and automotive electronic control units.

Construction and functioning of the PS9324L2-V-E3-AX optoisolator is based on the principles of photonics. Infrared light is emitted from the InfraRed LED on one side when a voltage is applied across the two pins. This light is then detected by the phototransistor on the other side. The phototransistor triggers and amplifies the signal which is further transmitted to the output. As this process eliminates any direct electrical connection between input and output circuits, the device also provides emission suppression and significantly improves noise immunity.

Thanks to its excellent insulation characteristics, high immunity to electromagnetic interference, and highly reliable performance, the PS9324L2-V-E3-AX optoisolator is one of the best products on the market in the logic output optoisolator category. It is also one of the most cost-effective devices in this range and can be used in a wide range of applications.
