Optoisolators are devices that use light optics to transfer electrical signals between circuits, reducing the risks associated with electrical shock and power surges. The PS9822‑1‑L‑AX is a type of optoisolator in the Logic Output category. As the name implies, this application field is for transferring signals with a logic level output. Its working principle is based on physical light and electrical energy.

The optoisolator is used to isolate one circuit from another, allowing them to communicate without coming into direct contact. It does this by using two separate LED — an infrared transmitter diode and an infrared receiver diode. The former emits light when activated, while the latter captures and converts the transmitted infrared into electrical signals.

The device consists of a lightweight, flat, black plastic housed device with two electrical connections and one transparent window on the top. The electrical connections are the input and output ports. The input port is connected to the circuit that will generate the signal, and the output port is connected to the circuit that will receive the signal. Inside the device are the LEDs and a photosensitive semiconductor chip.

When an electrical signal is applied to the input port, the infrared transmitter diode emits light and is detected by the infrared receiver diode. The photosensitive semiconductor chip then converts the infrared signal into an electrical output. The electrical output is then sent to the output port.

The device can be used for a variety of applications, such as testing circuits, controlling PCBs, and isolating power supplies. It is also suitable for use in high-impedance circuits, as it can withstand high voltages and temperatures.

The PS9822‑1‑L‑AX is capable of transmitting low-current signals, with a typical operating current of 10mA and a maximum operating current of 20mA. It has a response time of 1.5uSec from the time the signal is applied to the input port to the time the output is enabled. It also has a dropout voltage of 2.2V and an on/off ratio of 2:1.

The PS9822‑1‑L‑AX is well suited for use in noisy environments, as it has excellent noise immunity. Additionally, it is designed to be used in a wide range of temperatures, from ‑25°C to 85°C. It has a minimum drain‑source on-state resistance of 4.7 ohms. The device is RoHS compliant and UL certified.

The PS9822‑1‑L‑AX optoisolator provides reliable electrical signal transmission between circuits. Its design and features make it perfect for a variety of applications, from controlling PCBs to testing circuits. It is capable of withstanding high temperatures and voltages, and is designed to provide electrically isolated communication even in noisy environments.
