Description:
The OPIA800 through OPID804 optocouplers are designed for applications that utilize a digital output
(Phototlogic®) in a dual-in-line package. Isolation voltage from 2,500 to 5,000 Volts RMS product are designed for
some of the most stringent power system isolation requirements.
Theory of operation: The LED transmitter is used to illuminate the Photosensor providing electrical isolation
between two power systems while maintaining the ability to transmit information from one power system to the
other. In many applications, analog or digital signals may be required to be transmitted between two power
systems while maintaining isolation between the power systems up to 5,000 volts RMS. A variety of LED and
photosensor configurations are available depending on the system requirements
The ratio Current Transfer Ratio (CTR) is determined using the output current and input current for analog
photosensors. CTR ratios can range from as low as 5 to over 9,000 depending on the device.
