I-7520A (RS-232 to RS-422/485, Isolation site RS-232)

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.

Features and Benefits

Auto-switching baud rate 300 bps to 115200 bps
3000 Vdc isolation protection on the RS-232 side

Transmission speed up to 115200 bps

ESD protection for the RS-232/422/485 data line

Power input of 10 Vdc to 30 Vdc

Operating temperature -25 °C to +75 °C

DIN Rail mountable

Product Application Information

The I-7520A lets you easily build an industrial grade, long-distance communication system using standard PC hardware.


The RS-422 and RS-485 cannot be used simultaneously.
