Allen-Bradley 1747-PIC Personal Computer Interface Converter

The Allen-Bradley 1747-PIC Personal Computer Interface Converter is a bridge between a PC’s RS-232 serial port and a DH-485 network used by SLC 500 controllers and PanelView terminals. The unit provides an RS-232 PC interface via a 9‑pin D-sub connector and a DH-485 network interface via a 25‑pin connector, enabling PC-based configuration, monitoring, and data exchange with DH-485 devices on the same network. It is powered through the DH-485 link from the connected controller, and typically ships with a PC-to-converter cable to simplify wiring and setup. Common applications include connecting an IBM/PC-compatible computer to SLC 500 CPUs (such as the 5/03, 5/04, 5/05 series) and PanelView panels to enable DH-485 communications, diagnostics, and programming in legacy Allen-Bradley installations.
