Description
The I-7520AR is a high-performance low-cost RS-232 to RS-422 or RS-485 isolated converter packaged for convenience in a compact DIN rail mounted unit. One of the unique features of the product is its self tuning circuitry. This permits the unit to auto-detect baud rate and data formats and tune accordingly.
This RS-232 to RS-485/RS-422 converter has been specially developed for PLC users with the isolation being present between the power/communications from the PLC and the rest of the serial network.
