ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•3.5mm Terminal Connector: The hub adopts 3.5mm terminal block, can be matched with OK wires, fly wires, etc., sturdy and reliable. Onboard power isolation, can achieve electrical isolation of input and output terminals, enhancing the system anti interference ability.
•Optical Isolation: Onboard optical isolation effectively separates 485 master and slave devices, protecting them from damage caused by ground potential differences, static electricity, and surges, while minimizing ground loop issues between devices.
•Overcurrent and Surge Protecting: The 485 terminal includes overcurrent protecting, surge protecting, and gas discharge protecting circuits to ensure reliable operating.
•Terminal Resistor Switch: Features a DIP switch for selecting the onboard 120R termination resistor, allowing customization based on actual needs to enhance signal transmission stability and reduce interference.
•Supported Baud Rate: Supports baud rates up to 1 Mbps. Note that the actual baud rate supported by the module is limited by the rates of the connected devices and may need to be adjusted according to specific circumstances.
