PS9587L2-AX Optoisolator - Logic Output Application Field and Working Principle

The PS9587L2-AX optoisolator is an integrated circuit (IC) provided by the STMicroelectronics corporation. The device is designed to isolate digital signals between two subsystems. This allows communication between two electronically isolated systems or circuits while preventing the interactions or current leakage between them.

The optoisolator creates an extra level of protection and isolation for sensitive circuitry. It is also useful in high-impedance applications and other areas where digital signals must be completely isolated. The PS9587L2-AX is suitable for applications requiring fast switching times, low noise, and low power consumption.

This optoisolator is classified as a logic output device since it provides logic signaling based on the signal levels detected by the input from the control system. The PS9587L2-AX has two integrated output channels, each providing logical high or low level outputs in response to the signal levels from the controller. The output channels are configured to be either a logic high (on) or a logic low (off) depending on the input signal.

The working principle of the PS9587L2-AX is based on the operation of an opto-coupler. An integrated photo-transistor is used to detect the level or voltage of the input signal, and then switches an appropriate output. The opto-coupler is further encapsulated in its own integrated circuit package to provide additional protection and insulation from outside interference.

In applications where there is a need to switch between high or low logic levels, such as in an industrial controller, the PS9587L2-AX optoisolator offers a reliable solution. It allows for isolated digital communication between two subsystems without the risk of ground loops, voltage transients, or other disruptive interferences. The device also consumes low power, making it an ideal choice for low-energy applications.

The PS9587L2-AX optoisolator is a cost-effective solution for those needing an isolated logic output device. Its advantages include fast switching times, low power consumption, noise immunity, and added protection from outside interference. With the high level of performance that the PS9587L2-AX optoisolator offers, it is the optimal choice for a variety of logic output applications.
