定义
In industrial machinery, a coupling circuit is an electronic or electrical component designed to transfer signals, power, or data between different sections of a machine's control system, such as between sensors and actuators in a trigger system. It ensures proper signal integrity, impedance matching, and electrical isolation, preventing interference and enabling reliable operation in noisy industrial environments. Common types include capacitive, inductive, and optical coupling circuits.
工作原理
The coupling circuit operates by using passive or active components (e.g., capacitors, transformers, optocouplers) to transfer energy or signals from one circuit to another while blocking direct current (DC) or providing electrical isolation. In a trigger system, it might condition sensor signals (e.g., from proximity switches) to activate actuators (e.g., solenoids or motors), ensuring precise timing and preventing ground loops or voltage spikes.
材料
Typically includes copper conductorsinsulating materials (e.g.PVCceramic)semiconductor components (e.g.diodestransistors for active circuits)and encapsulation materials (e.g.epoxy resin). For optical couplingmaterials include LEDs and phototransistors.
