Allen-Bradley 1734-232ASC ASCII Interface Module

The Allen-Bradley 1734-232ASC is a POINT I/O RS-232 ASCII Interface Module that provides a single ASCII channel to connect serial devices to a ControlLogix or CompactLogix system through a POINT I/O rack. It enables the PLC to send and receive ASCII strings over RS-232 with external equipment, such as barcode scanners, serial printers, scales, or other ASCII-based peripherals. As part of the POINT I/O family, the 1734-232ASC plugs into a POINT I/O chassis and uses module-defined data types to map incoming and outgoing ASCII data to PLC tags, simplifying programming in Studio 5000. This one-channel ASCII interface is designed specifically for serial communication within the POINT I/O architecture, offering a straightforward way to integrate legacy or text-based devices without a separate gateway. Typical applications include data collection from serial devices, issuing simple ASCII commands to equipment, and reading textual responses for process control or monitoring in industrial automation environments.
