[1 IN 8 OUT ISOLATED HUB] This industrial grade 485 hub features 1 isolated RS485 input channel and 8 isolated output channels, supporting up to 128 nodes per channel. The star bus structure allows flexible network expansion while maintaining signal integrity through complete photoelectric isolation between all ports.
[ULTRA STRONG PROTECTION] Equipped with advanced 2500Vrms optoelectronic isolation and 600W peak guard circuits, this hub provides superior protection against ESD (±15KV), strikes, and common ground interference. The robust design ensures stable operation in harsh industrial environments.
[AUTOMATIC ENABLE CONTROL] Smart automatic switching technology eliminates transfer/reception conversion delays, ensuring seamless bidirectional communication. The adaptive baud rate supports 300bps to 115.2Kbps without protocol limitations for universal compatibility.
[COMPREHENSIVE PORT SAFETY] Each 485 channel features independent short circuit and open circuit protection, enabling safe bus structure improvements and fault channel isolation. The design prevents network-wide failures when individual segments malfunction.
[VERSATILE POWER OPTIONS] With wide voltage DC9-40V power input (recommended 24V 1A), this repeater is ideal for outdoor engineering applications. The compact 122x72x26mm ABS housing withstands temperatures from -40℃ to 85℃ with 5%-95% humidity tolerance.
