Industry Applications
The Allen-Bradley 1747-UIC excels in applications where legacy DH-485 devices must interface with modern USB-equipped computers. Common scenarios include:
- Programming and configuring SLC 500 controllers using Rockwell Software RSLogix 500.
- Connecting PanelView terminals for HMI monitoring and data acquisition.
- Integrating MicroLogix and ControlLogix controllers into a unified maintenance network.
In a typical retrofit project, the 1747-UIC replaces older serial interface cards, reducing setup time and improving connection reliability.
Installation & Setup Guidance
Installing the 1747-UIC is straightforward. Connect the converter to your computer via the USB port; the device draws power directly from the USB connection, eliminating the need for an external power supply. Use the switch-selectable DH-485 ports to connect to your DH-485 network, and the RJ-45 port for direct connections to SLC 500 controllers. Ensure the communication rate is set to 19200 bits/second for optimal performance. The compact design (109mm x 50.6mm x 31mm) allows easy mounting in control cabinets or on workbenches.
Maintenance & Reliability
With no moving parts and solid-state construction, the 1747-UIC requires minimal maintenance. Operating within its specified temperature range of 0 to 60°C ensures long-term reliability. Periodically inspect the USB and DH-485 connections for dust or corrosion, and verify that the cable lengths remain within recommended limits to avoid signal degradation. The 500V DC isolation protects against ground loops, reducing the risk of communication errors.
Compatibility & Integration
The 1747-UIC is designed for seamless integration with Rockwell Automation platforms. It works directly with SLC 500, MicroLogix, and ControlLogix controllers, as well as PanelView terminals featuring DH-485 ports. The converter supports Ethernet and RS-232 communication, providing flexible connectivity options for various industrial setups. Its USB interface ensures compatibility with modern PCs running Windows-based programming software.
Selection Guide & Purchasing Advice
Before purchasing the Allen-Bradley 1747-UIC, verify that your computer has an available USB port and that your target controllers or terminals are DH-485 compatible. The converter is ideal for both new installations and upgrades from older serial interfaces.
