Working Principles

ACPL-7970-300E utilizes an LED (Light Emitting Diode) to emit light when current flows through it. This light is then detected by the phototransistor, which generates an output current proportional to the input current. The optocoupler provides electrical isolation between the input and output circuits, preventing any direct electrical connection.

Detailed Application Field Plans

1. Industrial automation: Signal isolation in PLC (Programmable Logic Controller) systems
2. Power electronics: Voltage level shifting in motor control circuits
3. Medical equipment: Isolation of sensitive components in patient monitoring devices
4. Automotive electronics: Protection against voltage spikes in automotive control systems
5. Telecommunications: Signal transmission in high-speed data communication networks
