Multi Way Optocoupler

Multi Way Optocouplers for Safe Signal Transmission

An optocoupler is an electrical component for safe transmission of digital or analog signals. The galvanic isolation of the signal distance between sender and receiver is a characteristic of the optocoupler. Therefore, transmission of parasitic currents is avoided in a reliable way. In addition to one way optocouplers there are also multi way versions of this component. These are more efficient and easier to install for multiple parallel signal distances.

When are Multi Way Optocouplers used?

Optocouplers are used if parasitic currents may occur along the signal distance. The transmission security is increased by transforming the electric impulse into a light signal and afterwards back into an electric signal.

How does a Multi Way Optocoupler Work?

Optocouplers include a sending and a receiving element. The sending element is the source of light. It is either an LED or a laser diode. In its close proximity is the receiver (e.g. a photocell). The preferably close proximity of sender and receiver guarantees an accurate signal transmission. Optocouplers have an enclosed housing to prevent light from the environment to enter. A multi way optocoupler consists of multiple components of such type in a single housing.

Where are Multi Way Optocouplers used?

Optocouplers are used wherever signal distances require a galvanic interruption. Typical examples include interface cards of computers. In such case they avoid interaction of different ground potentials. Within acoustic amplifier technology multi way optocouplers are used to avoid the danger of ground loops.
