Working Principles

The ACPL-7900-300E is an optocoupler that utilizes a phototransistor to provide electrical isolation between the input and output circuits. When an input signal is applied to the LED (Light Emitting Diode), it emits light that activates the phototransistor. The phototransistor then allows current to flow through its collector-emitter path, effectively transferring the input signal to the output side.

Detailed Application Field Plans

1. Industrial automation: Isolation of control signals in PLCs (Programmable Logic Controllers), motor drives, and power supplies.
2. Telecommunications: Isolation of high-speed digital signals in communication systems, such as Ethernet and RS-485 interfaces.
3. Medical equipment: Isolation of sensitive analog signals in patient monitoring devices and medical imaging systems.
4. Automotive electronics: Isolation of signals in automotive control modules, battery management systems, and electric vehicle charging stations.
