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.
