Allen-Bradley 1747-KE DH485 RS232C Interface Module

Allen-Bradley 1747-KE DH-485/RS-232C Interface Module is a SLC 500 communications bridge that connects a DH-485 token-passing network to a PC or DF1 serial device via RS-232C. The module provides a DH-485 port for network token-passing, a DF1 RS-232C port for direct serial communications, and a dedicated DF1 configuration port for setup and diagnostics. When used with 1747-C11 or 1747-C13 cables, it enables DF1 communication between a PC or terminal and the SLC 500 controller, while the DH-485 side supports connection to DH-485 peripherals on the same network. This interface is designed to install in a standard SLC 500 rack slot and is compatible with the SLC 500 family of controllers. Typical uses include programming, monitoring, and data exchange for SLC 500 projects where sustained RS-232 serial access and DH-485 network integration are required. The 1747-KE supports common DF1 and DH-485 communication patterns used by legacy Allen-Bradley devices, providing a robust bridge between RS-232C-enabled equipment and DH-485 networks.
