Working Principles

The ACPL-785J-500E is an optocoupler that utilizes a phototransistor to provide electrical isolation between the input and output circuits. When a current is applied to the input LED, it emits light that activates the phototransistor. The activated phototransistor allows current to flow between the collector and emitter, providing signal transmission while maintaining electrical isolation.

Detailed Application Field Plans

  1. Industrial automation: Isolation and signal transmission in PLC (Programmable Logic Controller) systems.
  2. Power electronics: Isolation and feedback control in motor drives and inverters.
  3. Medical equipment: Isolation and protection of sensitive components in patient monitoring devices.
  4. Telecommunications: Isolation and signal transmission in communication systems.
  5. Automotive: Isolation and signal transmission in automotive control modules.
