Description:
The OPIA series optocouplers are designed for applications that use an analog output (Phototransistor or
Photodarlington) in a dual-in-line package. A wide selection of configurations are available. With typical isolation
voltage of 5,000 Volts(RMS), these products meet typical 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 signal levels 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 by 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.
