Allen-Bradley 9300-USBS USB Cable Assembly with Shielding

The Allen-Bradley 9300-USBS USB Cable Assembly with Shielding is a shielded USB-to-RS-232 serial adapter cable sold as an accessory by Allen-Bradley (Rockwell Automation) to connect a PC directly to legacy Allen-Bradley equipment. As part of the 9300 family, this cable provides a USB interface on the computer end and a serial interface on the device end, enabling serial communications with AB controllers and terminals without needing a separate third‑party adapter. This accessory cable is commonly used to configure and communicate with older AB hardware such as MicroLogix, SLC 500, and PanelView devices, supporting standard RS-232 signaling in typical industrial environments while the shielding helps minimize electromagnetic interference and preserve signal integrity during setup, diagnostics, and data transfer.
