Luqeeg RS485 Hub, Industrial Grade 4 Port Optical Isolation Splitter, 2500Vrms Photoelectric Isolation Hub with 600W Protection, Ideal for RS485 Star Bus Structure Communication

1. STRONG ISOLATION: The 485 interface uses photoelectric isolation technology to prevent thunder shocks from introducing converters or equipment. The built in photoelectric isolator and 600W shock protecting circuit can provide isolation protecting up to 2500Vrms, which can effectively inhibit thunder and ESD, and can effectively prevent thunder strikes and common ground interference 2. AUTOMATIC CONTROL: Automatic switching enables the isolated hub to control the circuit and easily solves the Recommended Standard 485 transceiver conversion delay problem 3. GUARD FUNCTION: Each port of isolated converter has short circuit and open circuit protecting, so users can easily improve the 485 bus structure, divide the network segment, and isolate the fault channel 4. DC 500MA WIDE VOLTAGE POWER SUPPLY: Isolated hub with external switching power supply, safe and trusted, very suitable for outdoor engineering applications 5.
