PRODUCT DESCRIPTION
ADAM-4520 Isolated serial interface converter
The Advantech ADAM-4520 is an isolated serial interface converter for connecting an RS-232 port to RS-422 or RS-485 wiring. It supports selectable data rates from 1200 bps to 115.2 kbps and automatic RS-485 data direction control.
The module accepts 10 to 30 V DC and provides 3000 V DC isolation. A female DB9 connector serves the RS-232 side, while a removable screw terminal carries the RS-422 or RS-485 connections. Internal switches set the operating mode, baud rate and character length.

SYSTEM INTEGRATION
Integrate ADAM-4520 within ADAM-4000
Select the RS-422 or RS-485 mode to match the installed serial link. Use the DB9 on the RS-232 side and the labeled plug-in terminals on the field side.
Match the converter and connected ports for baud rate and character length. The startup manual gives 9600 bps and 10 bits as the default settings.
Check polarity at the 10 to 30 V DC supply terminals and verify the data-flow indicator during a bidirectional test. Review termination and wiring against the Advantech startup manual.
Features:
- Input interface: RS-232
- Output interfaces: RS-422 or RS-485
- ADAM-4000
Use ADAM-4520 only within the documented ADAM-4000 arrangement and applicable installation instructions.
INTERCHANGEABILITY
Replace ADAM-4520 within ADAM-4000
Capture the full product label and record the switch positions before removing the converter. Check whether the installed connection uses RS-422 or RS-485.
Compare the field-side pin assignment and the DB9 cable wiring against the manual. Restore the approved speed and data format before reconnecting the serial link.
Verify that data passes in both directions and check the indicator for the expected mode. If a transfer fails, compare the switch settings and terminal polarity to the recorded configuration.
Features:
- Input interface: RS-232
- Output interfaces: RS-422 or RS-485
- ADAM-4000
Use ADAM-4520 only within the documented ADAM-4000 arrangement and applicable installation instructions.
