Introduction:
Optoisolators are electronic components that use light to transmit electrical signals. They are commonly used to protect electronic devices and systems from high voltages, overwhelming noise, and other undesirable electrical events. As the name suggests, optoisolators isolate the input signals from the other electric components and systems, providing a reliable and safe method of controlling and monitoring electronic equipment and systems. Optoisolators are available in many different varieties, each configured for a specific application. One of these varieties is the 6N137S (TA) optoisolator, a logic output optoisolator that has a variety of applications.
6N137S (TA) Application Fields:
The 6N137S (TA) optoisolator is a logic-output optoisolator that is designed to isolate signals up to a maximum of 10mA, a maximum operating voltage of up to 48V, and a maximum load current of up to 5mA. This type of optoisolator is primarily used in digital logic circuits, such as computer and logic controllers, to protect the circuits from electrical interference, noise, and other disruptive interference. Additionally, the 6N137S (TA) optoisolator is well-suited for use in applications that require the transmission of digital signals over long distances, since they are not affected by EMI or electrostatic interference. The 6N137S (TA) optoisolator is also widely used in motor control circuits and other electrical systems, as it provides reliable isolation between input and output signals.
6N137S (TA) Working Principle:
The 6N137S (TA) optoisolator operates on the principle of light transmission. It consists of two main components, the light source and the phototransistor (input switch). The light source is typically an LED, and when an electric signal is applied to it, the LED emits light. This light passes through a light-transmitting medium (such as a quartz lens) and is detected by a phototransistor (input switch), which switches on or off in response to the light. The phototransistor then provides the output signal that can be used to control other circuits.
Conclusion:
The 6N137S (TA) optoisolator is a logic-output optoisolator that is designed to operate up to a maximum of 10mA, a maximum operating voltage of up to 48V, and a maximum load current of up to 5mA. It is primarily used in digital logic circuits, such as computer and logic controllers, to protect the circuits from electrical interference, noise, and other disruptive interference. Additionally, it is also well-suited for use in motor control circuits and other electrical systems, providing reliable isolation between input and output signals. 6N137S (TA) optoisolators operate on the principle of light transmission, using light-emitting diodes and phototransistors to transmit and control signals.
