Applications

CONV232-485 is used for EXOline communication. As most industrial computer systems provide standard RS232 serial ports, the RS232 to RS485 converter is used to convert these RS232 signals to isolated RS485 signals. The converter can be used for long-distance communication.

Limitations

The maximum transfer distance is 1200 m at transmission speeds of 9.6 kbps (400 m at 115.2 kbps). For longer distances a repeater is required.

Installation

The RS485 cable as well as the 24 V DC power supply are connected to the converter via a removable 10-Pin terminal block. The RS232 cable connects to the converter via a 9-Pin female D-Sub.

The converter can, if required, easily be mounted on a DIN-rail.
