Description
1. Product Title
Allen-Bradley 1747-UIC – USB to DH-485 Industrial Communication Interface Converter
2. Product Overview
The 1747-UIC is an original protocol conversion accessory manufactured by Allen-Bradley (Rockwell Automation), engineered to establish stable data links between modern USB-enabled laptops and legacy DH-485 industrial control networks. As a critical communication bridge for the SLC 500 PLC series, it converts USB signals to the proprietary DH-485 bus protocol, eliminating the limitation of obsolete RS-232 serial ports on current industrial computers. Powered entirely by the host USB port without external power adapters, 1747-UIC supports program upload/download, online fault diagnosis, real-time parameter modification and runtime data collection via RSLogix 500 and RSLinx software. Built-in electrical isolation suppresses field electromagnetic interference, effectively protecting both the programming terminal and the PLC processor from voltage surges, and guarantees consistent communication reliability during long-term on-site maintenance of legacy automation control systems.
