1747-UIC SLC 500 USB to DH-485 Interface Converter | Allen Bradley

Product Overview

The Allen Bradley 1747-UIC functions as a high-performance communication link between a modern PC's USB port and industrial DH-485 networks. This converter allows engineers to program, monitor, and troubleshoot SLC 500, MicroLogix, and PanelView devices that utilize the legacy DH-485 protocol. It eliminates the need for obsolete PCMCIA cards or dedicated serial ports on laptops. We supply this unit as a 100% Brand New, original factory device to ensure stable data transmission and full compatibility with RSLinx Classic software.

Technical Specifications

The 1747-UIC provides dual-port flexibility to support different DH-485 physical connection types.

Engineering Advantages

• Dual Interface Versatility: The 1747-UIC features both an RS-232 (9-pin D-shell) and an RS-485 (RJ-45) port. This design enables connection to a wide variety of hardware, ranging from SLC 5/03 processors via the serial port to SLC 5/01, 5/02, and 5/03 processors via the RJ-45 network port.

• Bus-Powered Convenience: The converter draws less than 100 mA directly from the computer's USB port. This removes the requirement for external power supplies or batteries during field service and troubleshooting sessions.

• Real-Time Diagnostics: Three integrated LED indicators provide instant feedback on the connection status. These LEDs allow technicians to verify USB power, converter health, and active DH-485 network traffic at a glance, speeding up the debugging process.

• RSLinx Seamless Integration: The hardware emulates a DF1 driver or a specialized UIC driver within RSLinx. This ensures that the software recognizes the DH-485 network nodes exactly as it would with a native desktop interface card.

• Rugged Industrial Build: Designed for the factory floor, the 1747-UIC withstands temperatures up to 60°C. The internal circuitry resists electromagnetic interference, maintaining a stable 19.2 Kbps baud rate even in electrically noisy environments.

FAQs

• Is this 1747-UIC unit a new original or a generic equivalent?

  We sell only 100% Brand New, original Allen Bradley 1747-UIC converters. Original units ensure the correct timing required for the sensitive DH-485 token-passing protocol, which generic USB-to-Serial adapters often fail to maintain.

• Can I use both the RS-232 and RS-485 ports simultaneously?

  No. You must select either the RS-232 or the RS-485 port using the physical switch located on the side of the device. The converter only communicates through one port at a time.

• Does the 1747-UIC require a specific driver?

  Modern versions of RSLinx Classic (v2.51 or later) include the necessary "USB to DH485" drivers. Once connected, the computer recognizes the device, and you simply configure the DH485 UIC devices driver in the RSLinx "Configure Drivers" menu.

• Can I connect this directly to a SLC 5/04 or 5/05?

  The 1747-UIC works with SLC 5/04 and 5/05 processors only if you have configured their serial ports for DH-485 protocol. It does not support the Data Highway Plus (DH+) protocol used by the SLC 5/04 or the Ethernet protocol used by the 5/05.
