RS485 hub HUB 2 port 485HUB hub with photoelectric isolation protection
1.Product introduction It is a RS-485 bus-division hub designed for RS-485 system used in complicated electromagnetic environments. It supports data communication rate up to 115.2KBPS. Photoelectric isolation technique is introduced to the RS-485 interface to prevent converter and device from lightning and surge voltage for ensuring the safe and reliable data communication. The built-in photoelectric isolator (an isolation voltage as high as 2.5KVrms) and 600W surge suppressor can effectively suppress lightning and ESD and the grounding interference with each RS-485 line. It uses external switching power supply for safety and reliability and is ideal for outdoor engineering applications. The built-in discrimination circuit can automatically sense the direction of data flow and switch the enable control circuit to ensure the automatic switch of transmit and receive in RS-485 mode. RS-485 is widely used in thruway toll system, road supervision system and electric power acquisition system as a high-performance and economical data interface converter. Short-circuit and open-circuit protection are provided for each port. Users can improve the RS-485 bus structure and divide bus segments conveniently for improved communication reliability. If lightning or faults occur then the failed segment will be isolated and make sure other segments can operate normally. This feature significantly improves the reliability of existing RS-485 network and reduces maintenance interval. Reasonable use of RS-485HUB can help to design a unique, highly reliable RS-485 system. 2.Product parameter 1. Interface: Compatible with RS-232 and RS-485 standards of EIA/TIA 2.
