Optoisolators are components primarily used to design electrical circuits for the purpose of isolating control signals from each other. One of the more important types of optoisolators is the logic output type, which can provide electrical isolation from 5V to 200V. The PS9851-1-AX is a logic output optoisolator module from NTE electronics which offers the high levels of electrical isolation required for high-speed data transfer and switching applications over long distances.

The PS9851-1-AX optoisolator consists of a gallium arsenide infrared detector optically coupled with a photo-transistor. This device features independent modulated drive operation, a low saturation voltage, and a high inter-turn isolation voltage. It can tolerate input signal variations ranging from 5V to 200V, which greatly makes it suitable for high-speed data transfer over long distances. Additionally, its maximum frequency range is greater than 10MHz, allowing for high-speed and efficient data transfer over a wide range of applications in different industries.

In terms of its physical design, the PS9851-1-AX is a surface mount component measuring 6.6 x 4.5 x 2.1 mm, capable of dissipating a maximum amount of energy at 250 mW while boasting a two-digit display index. Its lead frames are made from an alloy of Nickel-Silver, while the housing is made of a high insulation material. This means that the components is able to retain its physical and electrical properties even in extreme temperatures and corrosive atmospheres.

As far as its application field is concerned, the PS9851-1-AX is primarily used for high speed data transfer applications, typically in industrial, automotive, instrumentation, telecommunications, and computing industries. Some of the more common use cases include connection of low power real-time clock modules and analog-to-digital converters to microprocessors in monitoring and control systems. The module is also useful in providing isolation for clock drivers and timers in logic level separations of microcontroller systems.

Theworking principleof the PS9851-1-AX logic output optoisolator relies on the use of an LED operating in conjunction with a photo-transistor. The LED emits light when an electrical current is applied, and this light is conveyed to the photo-transistor, which will then switch between off/on states depending on the intensity of light. When the light intensity is low, the transistor gets into an “off” state, and when the light intensity is high enough, the transistor gets into an “on” state. This switching between the “off” and “on” states is what enables the optoisolator to transfer signals over long distances and provide the required level of electrical isolation.

In conclusion, the PS9851-1-AX logic output optoisolator is a reliable and efficient device for high-speed data transfer applications in a variety of industries. It is designed with a robust physical construction to ensure maximum durability and performance, while its modulated drive mode and wide frequency range makes it suitable for high performance applications. The module is easy to configure and provides high levels of electrical isolation, which make it a great choice for many applications.
