PC900V0NIPXF

PC900V0NIPXF is a type of logic output optoisolator which is designed for the applications of interfacing and isolating. It fulfills the need of isolation between two different systems that are running on different electrical characteristics, especially for some safety requirements. This device is featured with finger-safe terminals and conforms to the UL 244A safety standard. This section outlines the applications and working principle of the PC900V0NIPXF.
Applications
The PC900V0NIPXF is mainly used for isolating two different systems or indirectly communicating between them in different scenarios. It is a common choice for applications where the galvanic isolation is necessary, such as:

• Fieldbus isolators
• Power line transceivers
• AC/DC and DC/DC Interface
• Ground Loop Isolation lines

In terms of security and safety, the PC900V0NIPXF has advantages in the following scenarios:

• Medical systems
• Building control systems
• Industrial automation
• and Automotive & military field

Working Principle
The PC900V0NIPXF incorporates an optocoupler construction in which a LED light source is used to communicate between the input and the output. The isolation is achieved through the embedded optical barrier created by the optocoupler inside the PC900V0NIPXF. The relation between the input and output of the PC900V0NIPXF could be simplified as a logical NOT gate which indicates that whatever the output signal is a mirrored image of the input signal. When the input is low, the LED is blocked, which the output is not activated. Oppositely, when the input is high, the LED is activated, producing an output that triggers a receiver. This inverter feature of this model makes it especially suitable for applications like motor control, switch signal isolation, and more. The PC900V0NIPXF is designed for a maximum input voltage of 13.2V DC and an output current of 1mA. The bus repeats the input voltage to the output side, but the voltage is minimized to 40V DC,with turning off time of 110ns and a response time of 2μs when the output is changed from low to high. The PC900V0NIPXF has an operating temperature range of -40 to 105°C and relative humidity range from 5 to 95%.In conclusion, the PC900V0NIPXF is an logic output optoisolator designed for the interfaces and isolation between two different systems. It features high voltage isolation, finger-safe design, and an affordable cost, making it a widely popular choice for applications like medical systems, building control, industrial automation, power line transceivers, and more.
