ISO-485-100 – Physical Media Isolator

The isolator RS-485 (ISO-485-100) is intended to isolate electrically a RS-485 signal. When a product contains noise or spurious that can be transmitted in the RS-485 physical environment, this causes the entire row to be compromised. That is, the network master can not communicate with other devices on the line if one of them is injecting noise on entire screen. Through the ISO-485-100, the serial line is galvanically isolated from the line that may contain spurious and thus, the main line which contains the master is not affected. ISO-interface 485-100 may also be used as a signal repeater at a rate of up to 115200 bps.
