This family of addressable baud rate converters allows to add the address to a device equipped with a serial interface (RS232/422/485) allowing its connection in a RS485 multipoint network.
At the same time, these converters convert the standard (e.g. RS232 to RS485) with the possibility of interfering with the transmitted data format and galvanic isolation between the two interfaces. Depending on the configuration, the baud rate, number of data bits, parity and number of stop bits can be adjusted. The setting of these parameters can be different between the 2 ports.
The converters support asynchronous data rates up to 230.4 kbps through one or two twisted pair RS422/485 interface side.
The RS422/485 bus is protected against overvoltage by TVS diodes and fuses.
Available models
- ADA-1040A - RS232-RS422/485 Addressable Baud Rate Converter
- ADA-4040A - RS422/485-RS422/485 Addressable Baud Rate Converter
- ADA-4020A - RS422/485-Current Loop Addressable Baud Rate Converter (Can be supplied to order)
The devices allow low power supply in a power range from 10 to 30Vdc and are equipped with reverse polarity protection. It is also possible (on request) to supply the product with isolated power supply.
