PS2801A-4-A

PS2801A-4-A is a type of optoisolator that is commonly used in many different applications. Optoisolators, also known as optocouplers, prevent electrical noise from intersecting with other circuits in a device. PS2801A-4-A is categorized as a transistor photovoltaic output optoisolator.

The PS2801A-4-A optoisolator features an LED-type input side and a photocon (Photo-Controlled Transistor) output side. The input LED will emit light when voltage is applied to it, which is then received by the photocon in order to control the on/off state of the transistor. This type of optoisolator is capable of blocking voltages as high as 1000Vdc on the input side to the output side, which is useful in applications that require isolation or protection from electrical noise. It has an isolation voltage rating of 2500Vrms, and a current transfer ration (CTR) between 30 and 40 percent.

This optoisolator is typically used in motor control, servo control, data communication, and surge protection systems. It is also used to reduce malfunctions and shorten noise emission due to the strong isolation ability of the optoisolator. Additionally, it can support a wide range of temperature ranges.

PS2801A-4-A requires a wide range of input and output components in order to operate correctly. On the input side, a device with a terminal voltage of 12V and a maximum current of 10mA is needed. On the output side, an NPN phototransistor and a Resistor are required. A resistor is necessary for the phototransistor to operate correctly. For each optoisolator, there is a specific resistance value that must be used. This value is typically between 200 and 500 Ohms, depending on the application.

To summarize, the PS2801A-4-A is a type of optoisolator which is usually used in motor control, servo control, data communication, and surge protection systems. It features an LED-type input side and a photocon (Photo-Controlled Transistor) output side. It is capable of blocking high voltages of up to 1000Vdc and has an isolation voltage rating of 2500Vrms. Additionally, in order to operate correctly, the PS2801A-4-A requires an input device with a terminal voltage of 12V and a maximum current of 10mA, and an NPN phototransistor and a Resistor.
