The RS-232 to RS-422/485 converter by Delock transmits data between devices with standard RS-232 or RS-422/485 connection and is suitable for fieldbus systems. With its robust metal housing, the converter offers various mounting options and protects against interference from electrostatic discharges (ESD).
Terminating resistors
Internal terminating resistors can be switched on or off with pin headers.
Two RS-232 to RS-422/485 converters can be connected directly to each other and thus offer a range of up to 1200 m as an RS-232 extension.
