Optoisolators - Logic OutputThe PS9821-1-F4-AX optocoupler is a type of logic output optoisolator designed to connect an input signal from a control system to an output device in such a way that complete electrical isolation is maintained between the two elements, ensuring that signals or current spikes from the control system do not interfere with the output device. It is ideal for use in applications that require galvanic isolation such as medical equipment, measurement, and industrial automation systems.The PS9821-1-F4-AX is a single channel optocoupler and features an LED on one side that is connected to an IC-output phototransistor on the other side, allowing it to switch electrical signals between its two sides without any contact between them. It features a wide supply voltage range of 4.5V to 22V DC and offers high noise immunity, up to 50 dB (1 MHz to 5 MHz).This optocoupler is especially useful in signal transmission scenarios where the two sides of the circuit are not compatible or electrically accessible to each other since its isolation distances are as large as 17 mm (depending on the model). Its low ON-state resistance of just 75 ohms makes it perfect for use in applications where efficient power transmission is sought.The PS9821-1-F4-AX utilizes a detection system in which the output is activated when the LED detects a certain amount of light. This is known as the photocurrent transfer gain and is measured in percent (%). The percentage value indicates the luminous intensity that needs to be met for the ON-state to occur. In the case of a PS9821-1-F4-AX device, the photocurrent transfer gain is 8 to 9 %.In addition to these features, the PS9821-1-F4-AX is also wear-resistant and provides high levels of temperature stability. It can operate in temperatures ranging from -25 degrees to +85 degrees Celsius, and its insulation distance is also quite high, being rated at 1.25kV per 1 minute.The PS9821-1-F4-AX can be used in a wide variety of professional applications, including those in the industrial, medical, and robotic industries. It is also suitable for environments with electromagnetic interference, making it excellent for producing consistent results in test systems. Thanks to its high noise immunity and low ON-state resistance, it is an essential component for systems that require reliable performance and accuracy. In motion control setups, the PS9821-1-F4-AX is especially useful for decreasing manufacturing times and preventing errors.All in all, the PS9821-1-F4-AX is an excellent option for applications that are concerned with maintaining high levels of isolation between their input and output components. This optocoupler features a versatile supply voltage range and wide temperature stability, making it ideal for both commercial and industrial applications.
