Allen Bradley 1747-FC Ferrite Collar EMI/RFI Suppression

Product Overview

The Allen Bradley 1747-FC ferrite collar belongs to the SLC 500 series. It filters electromagnetic and radio frequency interference. This accessory works with RS-232 cables. It protects controllers like the 1747-L541, L542, and L543. The collar uses a ferrite core for noise attenuation. A plastic housing ensures durability. Installation is simple and fast. The collar meets European EMC Directive standards. It improves system reliability by reducing electrical noise.

Application Scenarios

Use the 1747-FC in industrial automation environments. It is ideal for SLC 500 programmable logic controllers. The collar fits on RS-232 communication cables. It reduces interference from motors or drives. Place it where the cable exits the module. This location gives the best noise suppression. The collar works in HVAC, SCADA, and material handling systems. It supports high-speed data integrity. Use it in factories, warehouses, or processing plants.

Technical Specifications

The 1747-FC uses a ferrite material for core construction. The housing is made of plastic. It is designed for RS-232 cables. Compatible controllers are 1747-L541, 1747-L542, and 1747-L543.
