This U485 industrial USB-RS485 converter converts computer USB signals to standard RS485 differential serial signals, a core communication accessory for industrial automation, PLC debugging, sensor data collection and monitoring equipment.
Equipped with integrated TVS surge protection and ESD anti-static circuits, the module effectively absorbs instantaneous high voltage surges and static interference, greatly reducing the risk of chip burnout in complex industrial power environments. The terminal block connector design simplifies wiring work; users only need to connect A, B and GND signal lines directly without extra adapters.
Adopting mature serial communication chip, it supports full duplex stable data transmission, with maximum communication distance up to 1200 meters when using shielded twisted pair cables. The onboard communication indicator lights clearly display sending and receiving status for quick fault checking.
No complicated configuration required after driver installation, compatible with all mainstream computer operating systems. Small-sized PCB with reserved fixing holes facilitates fixed installation inside control cabinets and equipment shells.
Suitable for industrial PLC communication, temperature/humidity sensor networking, access control system debugging, solar equipment monitoring and various RS485 bus industrial control scenarios.
