Product Summary
The Allen-Bradley 1747-UIC gives modern computers a direct link to legacy DH-485 networks. This converter powers through your USB port and provides 500V DC isolation. It supports a communication rate of 19200 bits per second for reliable data transfer.
Expert Technical Evaluation & Performance Review
This section provides a strict engineering critique of the 1747-UIC interface converter. We analyze its core specifications to help you understand its true performance capabilities.
The 1747-UIC operates as a USB to DH-485 bridge for the SLC 500 system. It draws power directly from the computer’s USB port, which simplifies field wiring. This design eliminates the need for an external power supply in most setups.
The converter’s USB interface achieves a transfer speed of 12 Mbps. This high-speed connection ensures fast data exchange between the computer and the DH-485 network. The converter then communicates at a baud rate of 19.2 Kbps on the DH-485 side.
Electrical isolation is a critical feature of this module. The 1747-UIC provides 500V DC circuit isolation between the USB power and the DH-485 common. This protection prevents ground loops and safeguards your connected equipment from voltage spikes.
The device uses flash memory for backup storage. This ensures that configuration settings remain intact after a power cycle. This feature reduces downtime during system restarts or maintenance procedures.
Environmental tolerances are well-defined for industrial use. The 1747-UIC operates reliably within a temperature range of 0 to 60 degrees Celsius. This range covers most typical control cabinet environments without requiring active cooling.
The module includes two switch-selectable DH-485 ports for flexible wiring. It also features an RJ-45 Ethernet port for direct connection to SLC 5/01, 5/02, and 5/03 processors. A single RS-232 DB9 port provides additional connectivity options for legacy devices.
Current consumption is a key consideration for USB-powered devices. The 1747-UIC draws less than 100 mA from the USB port. This low power draw ensures compatibility with standard laptop and desktop USB ports.
The backplane current requirements are 600 milliamps at 5 Volts and 90 milliamps at 24 Volts. These values are important for system power budget calculations. The converter’s weight is 1 pound or 0.45 kilograms, making it easy to mount.
The 1747-UIC supports a chassis with up to 30 module slots. This allows for significant system expansion without changing the interface converter. The module type is specifically a USB to DH-485 interface converter.
This converter connects directly to SLC 500, MicroLogix, and ControlLogix controllers. It also works with PanelView terminals that have DH-485 ports. This broad compatibility makes it a versatile tool for system integration.
