485 Optocoupler Isolated Serial Port Hub, 1 in 2 Out Half Duplex Transparent Transmission with 3.5mm Terminal Block Power Opto Isolation Surge Protection, for RS485 Communication
[ SIGNAL INTEGRITY & PROTECTION] Our industrial grade RS485 hub employs both onboard power isolation and advanced optocoupler isolation. This dual layer defense system effectively separates master and slave devices shielding your valuable equipment from damaging ground potential differences static electricity and power surges. It dramatically minimizes ground loop issues ensuring pristine signal quality and maximum system uptime in harsh electrical environments.
[ROBUST MULTI LAYER CIRCUIT PROTECTION] Engineered for reliability this hub features a comprehensive protection suite on its 485 terminals. It integrates overcurrent protection surge protection and a gas discharge tube to form an impenetrable barrier against voltage spikes and transient disturbances. This ensures stable and reliable operation protecting your entire network from unexpected electrical faults and extending the lifespan of connected devices.
[FLEXIBLE INSTALLATION & TERMINATION CONTROL] Designed for applications the hub comes with a sturdy 3.5mm terminal block compatible with OK wires and fly wires for secure connections. A user friendly DIP switch allows you to easily enable or disable the onboard 120 ohm termination resistor. This customization lets you optimize signal integrity and reduce reflections based on your specific network topology and cable length.
[HIGH PERFORMANCE LONG DISTANCE COMMUNICATION] Supporting baud rates up to an impressive 1 Mbps and communication distances extending to approximately 1200 meters this hub is built for demanding industrial networks. It facilitates half duplex transparent transmission and each port supports up to 32 nodes making it ideal for expanding and managing large scale distributed sensor and control systems with high speed data needs.
[ENHANCED MONITORING & DURABLE DESIGN] Stay informed about your network status with the onboard multi channel LED indicators which clearly display power supply and real time data transmission reception activity. Housed in a rugged ABS casing and featuring a compact rail mounted design (53.6x99.5mm) this hub is built for durability and easy integration into control cabinets ensuring long term performance in industrial settings.
