I-7520/I-7520A/I-7520R/I-7520ARI-7520: Isolated RS-232 to RS-485 ConverterI-7520A: Isolated RS-232 to RS-422/485 ConverterI-7520R: RS-232 to Isolated RS-485 ConverterI-7520AR: RS-232 to Isolated RS-422/485 Converter •Automatic RS-485 Direction Control •ESD Protection for the RS-232/422/485 Data Line •Power Input, +10 ~ +30 VDC •3000 VDC Isolation Protection on the RS-485 side •Transmission Speed of up to 115200 bps •Operating Temperatures, -25 °C ~ +75 °C •DIN-Rail Most industrial computer systems provide standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range, and networking capabilities. The RS-422 and RS-485 standards overcome these limitations by using differential voltage lines for data and control signals, which transparently converts RS-232 signals into isolated RS-422 or RS-485 signal with no need to change any hardware or software. The I-7520/I-7520A lets you easily build an industrial grade, long-distance communication system using standard PC hardware.
The design of the isolation between the I-7520 and the I-7520R/AR is different. If the user wants to supply power from the PLC/PC, the I-7520R/AR should be used, otherwise the isolation will be broken. Refer to the I-7000 bus converter manual for detailed information.
