Allen-Bradley 1747-PIC SLC 500 Interface Converter

The Allen-Bradley 1747-PIC SLC 500 Interface Converter is an RS-232 to DH485 gateway that lets a PC communicate with an SLC 500 DH485 network, enabling programming, monitoring, and diagnostics of SLC 500 controllers from a computer serial port. This kit includes the 1747-C10 cable for connecting the converter to the SLC 500 controller, delivering a complete PC-to-DH485 link for legacy Rockwell Automation systems.

• Interface: RS-232 on the PC side to DH-485 on the SLC 500 network, facilitating decades‑old SLC 500 programming workflows.
• Includes 1747-C10 cable for connection to the SLC 500 controller.
• Compatible with SLC 500 modular hardware and fixed controllers, supporting typical DH-485 network configurations found in industrial automation environments.
• Common uses include uploading and downloading PLC programs, online monitoring of ladder logic and I/O, and on-site diagnostics via a PC without a dedicated programmer port on the controller.

DH-485 networks are multi‑drop RS-485 links used by many SLC 500 devices, and the 1747-PIC provides a direct way to interface a PC with that network for maintenance and troubleshooting. The converter is positioned for use in legacy control rooms and field service settings where a stable, wired PC connection to an SLC 500 DH-485 network is required, offering a practical path to continue operating or updating older Allen-Bradley systems without newer USB or Ethernet interface options.
