Applications:
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.
Description:
UT-509 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.
