Hualian optocouplers, with excellent performance and stable reliability, are widely used in industrial automation equipment such as PLC, frequency converter/inverter, servo system, DCS, instrumentation, etc. They play a key role in isolation communication, isolation drive, signal feedback, switch, etc, ensuring the safe and stable operation of equipment under various working conditions. Among them, high-speed optocouplers are used for various communication interfaces such as RS-485, CAN bus, data transmission, computer peripheral interfaces, alternative pulse transformers, digital isolation for A/D and D/A conversion, etc. Gate driven optocouplers are used for gate driving of IGBT/MOSFETs in frequency conversion/inverter/BOOST topologies, and optical MOSFET relays are used as non-contact high and low voltage switches in DCS, PLC and instrumentation.

Hualian optocoupler has advantages of low power consumption and long lifespan, etc,it reduces the energy consumption of PLC systems and prolong their service life due to its efficient energy conversion and stable operating state . With the continuous development of automation technology, Hualian optocoupler will continue to play its vital role to promote the continuous innovation and optimization of PLC systems.
