The Allen-Bradley 1734-485ASC is a POINT I/O RS-485/RS-422 ASCII interface module. It provides one full-duplex serial communication channel for connecting serial ASCII devices to a POINT I/O system. The module supports RS-485 and RS-422 communication and operates from a 24 V DC POINT I/O power supply. Rockwell Automation currently lists it as Active.
