Product Details

Product model: FB-485HUB

FB-485HUB is a 4-port industrial grade RS-485 hub developed and produced by FBUS, which can forward data sent from one RS-232/485 serial port to four RS-485 serial ports. The product supports a transmission rate of up to 115.2Kbps, automatically senses the direction of data flow, and can automatically switch enable control circuits to achieve zero delay RS-485 data transmission and reception. Widely used in monitoring systems, data acquisition systems, etc. The FB-485HUB has 3KV optoelectronic isolation, which can adapt to various complex industrial environments. In addition, it has the function of detecting and automatically disconnecting from abnormal circuits. If a certain 485 signal is reversed or abnormal, it will automatically disconnect the circuit without affecting the use of other circuits. At the same time, the fault LED of that circuit will light up, making it convenient for users to quickly detect problems. It is a high-performance, stable and reliable serial port conversion product.
