• [INDUSTRIAL-GRADE PERFORMANCE] Engineered for demanding environments, this RS485 hub features industrial-grade ABS housing and core chips that deliver exceptional durability. With an operating temperature range of-30℃ to +75℃ and 1000VDC isolation voltage, it maintains in harsh industrial conditions while preventing bus failure from power supply voltage differences.
• [ADVANCED OPTICAL ISOLATION TECHNOLOGY] The hub's innovative optoelectronic isolation system eliminates ground loop interference and protects connected equipment from voltage spikes. This technology ensures clean signal transmission at speeds up to 115.2kbps across all four ports while maintaining complete electrical isolation between connected devices.
• [INTELLIGENT AUTO-SENSING FUNCTION] Featuring smart automatic data direction control, this hub eliminates the need for manual configuration. Its internal processor continuously monitors and adjusts transmission direction without external intervention, significantly simplifying installation in complex multi-node RS485 networks with up to 128 connections.
• [COMPREHENSIVE SAFETY PROTECTION] Designed with robust protection mechanisms including ±15kV ESD protection, 600W thunder protection, and automatic short-circuit isolation. The system provides visual alarm indications for faults and automatically isolates problematic channels while maintaining operation on unaffected ports.
• [VERSATILE CONNECTIVITY SOLUTION] Supporting transmission distances up to 1200m at 19.2kbps, this concentrator is compatible with both RS232 and RS485 standards. The combination of plug terminal and DB9 female interfaces accommodates various cable types, making it ideal for automation systems, security networks, and industrial control applications.
