Product Introduction
The Allen-Bradley 1747-FC Ferrite Collar is an electromagnetic noise suppression accessory specifically designed for programmable controller systems, particularly within the SLC 500 platform. It is primarily used on RS-232 communication cables to minimize the impact of high-frequency electrical noise that can interfere with data transmission and controller operation.
In industrial environments where variable frequency drives, contactors, relays, and high-power equipment operate nearby, communication lines are often exposed to EMI and RFI disturbances. The 1747-FC ferrite collar addresses this challenge by attenuating unwanted high-frequency signals while allowing normal data communication to pass unaffected.
The device is non-intrusive, requires no configuration, and can be installed quickly by clamping it around the target cable. Its passive design ensures long-term reliability with zero maintenance, making it an effective safeguard for communication stability in automation systems.

FAQ
-
What type of interference does the 1747-FC ferrite collar suppress?
It suppresses high-frequency electromagnetic and radio-frequency interference that can couple into communication cables and disrupt data transmission. -
Is the 1747-FC limited to use with SLC 500 systems only?
While optimized for SLC 500 controllers, it can be applied to other programmable controller systems using RS-232 communication. -
Does installing the ferrite collar affect signal quality or speed?
No, it selectively attenuates unwanted high-frequency noise without impacting normal signal transmission. -
Where should the ferrite collar be installed on the cable?
It is typically installed close to the controller or communication module where noise sensitivity is highest. -
Can multiple ferrite collars be used on a single cable?
Yes, in high-noise environments multiple collars may be installed to enhance noise suppression effectiveness. -
Is any configuration or programming required after installation?
No configuration or software changes are required, as the device operates passively. -
Does the ferrite collar require grounding?
No grounding connection is required for proper operation. -
Can it be used in systems with variable frequency drives nearby?
Yes, it is especially effective in environments with VFDs, contactors, and high-power switching devices. -
Is the ferrite collar reusable after removal?
Yes, it can be removed and reinstalled on another cable if needed. -
Does the ferrite collar introduce any latency or delay in data transmission?
No, it does not introduce measurable latency or affect communication timing.
