PS9614L-E3-A Optoisolators - Logic Output: Application Field and Working Principle

Optoisolators - Logic Outputs, also known as optocouplers, are widely used for logic level conversion and voltage-level separation between the input and output circuits. The PS9614L-E3-A is a digital output type optoisolator that integrates a LED and an NPN-drive transistor output in the same package. This device typically finds applications in AC motor control and PLCs (programmable logic controllers). This article is specific to the PS9614L-E3-A optoisolator and provides an overview of its general application field, working principle, and performance characteristics.

Applicationfield

The PS9614L-E3-A optoisolator is generally used for logic level conversion and voltage-level separation between the input and output circuits. This device is ideal for protecting the main circuits from shocks, noise, and other interferences. It is widely used in many electronic and electrical systems such as AC motors, PLCs, and data communication. This optocoupler is also used for optically coupling devices such as photo sensors, rotating encoders, switches, and relays to ensure safe and reliable signal transmission.

Working Principle

The PS9614L-E3-A optoisolator consists of two separate parts – an LED light source and an NPN-drive transistor output. The basic principle of these two parts is as follows. The LED is connected to the input circuit and emits light when a sufficient voltage is applied to it. This light is detected by the NPN-drive transistor output, which then switches on to supply the load with current. This device works in conjunction with optically coupled systems, allowing them to be electrically isolated, as well as providing protection from electric shocks, noise, and other interferences.

Performance Characteristics

The PS9614L-E3-A optoisolator features an isolation voltage of 5kV-8kV, with an isolation resistance of 100MΩ-500MΩ. It also has a LED forward current rating of up to 10mA, and a transistor output maximum collector current rating of 30mA. It operates over a wide range of temperature from -40℃ to +100℃, and provides an LED reverse voltage rating of 5V. This optocoupler is also protected against voltage spike damage of up to 15V in the off-state, as well as surge voltage ratings of 8kV peak pulse. In addition, the device has a continuous working voltage of 30V, with a total power dissipation of up to 0.25W.

In conclusion, the PS9614L-E3-A is a popular digital output type optoisolator that provides an excellent solution for logic level conversion and voltage-level separation between the input and output circuits. This device has several performance characteristics such as an isolation voltage of 5kV-8kV, LED forward current of 10mA, a transistor output of GEO 30mA, and a surge voltage rating of 8kV peak pulse.
