[INDUSTRIAL GRADE PERFORMANCE] This RS485 hub repeater features rugged industrial grade construction with complete photoelectric isolation for stable communication in harsh environments. It delivers reliable performance with transmission rates up to 115.2Kbps while protecting your equipment from electrical interference and voltage fluctuations.
[ADVANCED ISOLATION TECHNOLOGY] Equipped with built in DC DC isolated power supply module that creates complete electrical isolation between all ports. This innovative design prevents ground loops and protects connected devices from power surges while maintaining signal integrity across long distances up to 2500 meters.
[HIGH CAPACITY NETWORKING] Supports multi machine communication with each of the 4 channels capable of connecting up to 128 nodes simultaneously. The intelligent data flow control automatically manages transmission direction for efficient network traffic without data collisions or signal degradation.
[ROBUST PROTECTION SYSTEM] Features comprehensive protection including ±15KV ESD shielding 600W dual channel TVS protection and 2.5KV communication isolation. These multiple safeguards ensure your equipment remains secure from power surges strikes and electromagnetic interference.
[VERSATILE INSTALLATION] Designed for flexible mounting options including 35mm rail installation or 4 hole back plate mounting. The compact 115x90x40mm size fits easily in control cabinets while operating reliably in extreme temperatures from 30℃ to 70℃ with humidity over 95% RH.
