Industrial RS485 Opto-Isolated Hub

This 4-Port RS485 bus split hub stands out as a robust solution engineered to thrive within the demanding confines of large-scale RS485 systems and complex electromagnetic environments. Capable of transmitting data at speeds reaching 115.2Kbps, it incorporates advanced photoelectric isolation technology that safeguards against lightning surges and ensures secure data communication. Enhanced by a built-in opto-isolator and a 600W surge protection circuit, this hub boasts an impressive isolation voltage of up to 2500V, effectively mitigating interference from surges and electrostatic discharges.

The versatility of this device extends to its adoption of an external switch power supply, offering a safe and reliable option suitable for outdoor engineering applications. In its RS485 working mode, the hub delivers a remarkable transmission distance exceeding 1200 meters while maintaining stable operations. The inclusion of a discrimination circuit allows it to automatically detect data flow direction and manage the enable control circuit, thereby tackling the challenges of transmission and reception conversion delay seamlessly. With this capability, it finds extensive application in power acquisition systems, serving as a high-performance data interface conversion module.

The hub's star RS485 bus connection facilitates enhanced network structuring, where each port benefits from short-circuit and open-circuit protection. With an optical isolation voltage reaching 2500V, users can confidently improve the RS485 bus configuration, partition network segments, and bolster communication reliability. In events of malfunction or lightning strikes, the hub isolates the faulty network segment, ensuring that unaffected segments continue operating without interruption. This feature significantly enhances the dependability of existing RS485 networks and expedites maintenance procedures, making it an indispensable asset for maintaining robust communication infrastructure.
