Optoisolators – Transistor, Photovoltaic Outputs

The PVI1050 is a 4-pin opto-isolator from Panasonic that provides galvanic isolation between input and output circuits. This is achieved by making use of a low-power light-emitting diode (LED) optically coupled to an integrated photo detector which contains a photovoltaic generator. This opto-isolator is ideal for use in safety-critical applications and is used in many industrial and medical applications.

PVI1050 Application Field

The PVI1050 opto-isolator from Panasonic is designed for use in diverse applications such as programmable logic controllers (PLCs), data acquisition systems, frequency-controlled drives, remote control systems, motor-control systems, and many others. This opto-isolator can also be used for a variety of interface converters, current-loop converters, and solid-state relays. The use of opto-isolators in a variety of scenarios is critical to ensure safety and proper operation. The PVI1050 was specifically designed to meet the standards for safety isolation, which require superior performance for situations like interference suppression, ground fault protection, or threshold voltages.

PVI1050 Working Principle

The PVI1050 opto-isolator from Panasonic is extremely simple in operation. Its functionality is made up of a light-emitting diode (LED) which transmits a light signal across a small gap. When the LED is enabled, the light signal is transmitted to and detected by an integrated photo detector containing a photovoltaic generator. This photovoltaic generator is used to convert the light signal into a voltage, which is then passed through the opto-isolator to the output terminal. Basically, when the LED is enabled, a voltage is generated at the output terminal. The primary use of the PVI1050 opto-isolator is to provide electrical isolation between input and output circuits. As such, the PVI1050 is capable of providing stable and reliable isolation up to a specified capacity. The opto-isolator also blocks the passage of high voltages and signals, which helps protect internal circuits from spikes and outages. The opto-isolator also reduces leakage current and prevents the degradation of signal integrity. The PVI1050 has an operating temperature range of 0°C to +70°C. It also has a storage temperature range of -55°C to +125°C, and the maximum operating voltage is 250V AC. The isolation voltage rating for the PVI1050 is 1,500V AC, and the insulation resistance is >100MΩ.

Conclusion

The PVI1050 opto-isolator from Panasonic is designed for isolation and signal switching applications. It is primarily used for safety-critical applications, data acquisition systems, and programmable logic controllers. It operates on a basic principle where a light-emitting diode (LED) transmits a light signal that is detected and converted into a voltage by an integrated photo detector containing a photovoltaic generator. This opto-isolator is capable of stable and reliable isolation up to a specified capacity and helps protect internal circuits from spikes and outages.
