Allen-Bradley 1747-FC Ferrite Collar SLC 500 EMI Suppression

1747-FC Allen‑Bradley Ferrite Collar for EMI/RFI Suppression

Product Introduction

The 1747-FC ferrite collar from Allen‑Bradley provides essential noise suppression for SLC 500 communication cables. This small but critical accessory reduces electromagnetic interference (EMI) and radio frequency interference (RFI) on RS‑232 connections. Electrical noise from motors, drives, and other industrial equipment can corrupt data signals, leading to communication errors or controller faults. The 1747-FC effectively attenuates this unwanted noise, preserving signal integrity.

This collar works with standard RS‑232 cables used in SLC 500 systems. Specifically, it supports controllers such as the 1747‑L541, 1747‑L542, and 1747‑L543. Its snap‑on design makes installation quick and tool‑free. For optimal performance, place it where the cable exits the module. This position maximizes its noise‑filtering effectiveness.

Compliance and Safety Standards

The 1747-FC ferrite collar complies with the European EMC Directive. This compliance confirms its effectiveness in reducing electromagnetic emissions and improving immunity in industrial environments.

Using this collar helps your SLC 500 system meet EMC requirements for CE marking. It also reduces the risk of nuisance trips or communication dropouts caused by external interference. For installations in regulated markets, the 1747-FC provides a simple and cost‑effective solution for EMC compliance.

Installation Guidelines

Installing the 1747-FC ferrite collar requires no special tools or technical expertise. Follow these simple steps for proper installation:

First, identify the RS‑232 cable connected to your SLC processor or communication module. Next, open the collar by pressing the snap‑lock mechanism. Place the collar around the cable at the point where it exits the module. Then, close the collar firmly until you hear a click. This secures it in place.

For best results, position the 1747-FC as close as possible to the module's cable exit point. This location captures the interference before it travels along the cable. Additionally, you can install multiple collars on the same cable for enhanced suppression if needed.

Finally, verify that the collar does not slide along the cable. A snug fit ensures consistent noise attenuation. If you experience communication issues after installation, check the collar's position and reseat it if necessary.
