Optoisolators - Logic Output is the widest area application in the world. One of the popular product of this technology, PS9821-1-F4-A is in great demand due to its ability to separate signals from other systems. This optoisolator is composed of two LEDs (light emitting diode) and two phototransistors in the same plastic body. The two LED’s create a light beam between them, and this light beam is directed to the two phototransistors. This optoisolator is suitable for signal transmissions in different voltage levels. It has the ability to separate signals from other systems even if they are directly connected.

The PS9821-1-F4-A optoisolator has two major applications. First, it in used in signal transmission applications, where a signal from one system must be kept isolated from other systems. The use of this optoisolator prevents the noise and interference from the other systems. Second, it can be used to control the flow of electricity. Two different types of power level signals can be connected without any danger.

The working principle of this optoisolator is quite easily understood. In the device two LEDs and two phototransistors are placed opposite to each other in the same body. The two LEDs create a light beam, which is used to direct signals to the two phototransistors. When the signal from a system reaches the LEDs, the phototransistors turn on and cause the current to flow in the device. When the input signal is removed, the phototransistors turn off and the current stops flowing.

The PS9821-1-F4-A optoisolator has a high isolation voltage rating, which is suitable for signal and power isolation applications. This device offers a wide range of operating temperature of -20 to 85°C. It is built using advanced CMOS technology, which makes it suitable for a wide range of applications. The maximum switching capacity is 2000Vss and it has a high immunity to noise.

This optoisolator provides an excellent level of performance and reliability. It also offers a high level of safety, as it is able to separate signals from other systems even if they are connected directly. This makes it suitable for applications that require a high level of safety and reliability. The PS9821-1-F4-A optoisolator is a versatile device with many advantages.
