Product Overview
The Allen-Bradley 1747-FC ferrite collar is an essential accessory for the SLC 500 series, designed to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) that can degrade automation system performance. This compact, low-complexity component attaches to RS-232 cables at the point where they exit the controller module, providing a simple yet effective shield against electrical noise.
Compatible with the 1747-L541, 1747-L542, and 1747-L543 controllers, the 1747-FC ensures clean signal transmission, reducing the risk of communication errors and system downtime. Its ferrite core and plastic housing deliver durable, reliable filtering in industrial environments.

Industry Applications
The 1747-FC is ideal for any SLC 500-based control system where reliable RS-232 communication is critical. Typical applications include:
-
Manufacturing Lines: In automated assembly or packaging lines, the 1747-FC prevents EMI from motors and drives from corrupting programming or HMI communication.
-
Process Control: For chemical or pharmaceutical plants using SLC 500 controllers, the collar maintains stable data exchange between the processor and operator interfaces.
-
Utilities & Infrastructure: In water treatment or power distribution, the 1747-FC protects RS-232 links from interference caused by high-voltage equipment, ensuring uninterrupted monitoring.
Installation & Setup Guidance
Installing the 1747-FC is straightforward. Position the collar around the RS-232 cable at the exact point where the cable exits the controller module. This placement maximizes noise suppression. Snap the collar closed over the cable—no tools are required. Ensure the collar fits snugly and does not slide along the cable. For best results, install the collar on every RS-232 cable connected to the controller.
Maintenance & Reliability
The 1747-FC requires minimal maintenance. Periodically inspect the collar for cracks or signs of wear on the plastic housing. Keep the collar clean and free from dust or debris, which could affect its performance. Because it has no moving parts, the collar offers a long operational life, contributing to reduced downtime and lower total cost of ownership.
Compatibility & Integration
This ferrite collar is specifically designed for the Allen-Bradley SLC 500 series. It is fully compatible with the 1747-L541, 1747-L542, and 1747-L543 controllers. Use it with standard RS-232 cables to suppress interference that can disrupt communication between the controller and programming terminals, HMIs, or other serial devices.
