PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1756-RMC1/A (Series A). Check the corresponding technical data before specifying another hardware series.
Allen-Bradley 1756-RMC1 is a 1-meter fiber cable for 1756-RM redundancy modules in ControlLogix systems. This cable links two ControlLogix redundancy modules located in partner chassis. The optical connection supports direct data synchronization between partner controllers. It provides the dedicated communication pathway for redundant architecture configurations. The 1-meter length serves chassis mounted within the same cabinet enclosure. It maintains optical traffic between redundant ControlLogix processing nodes.
The 1756-RMC1 optical assembly is identified as 1756-RMC1/A in Series A hardware revisions. This fiber-optic medium attaches directly to front optical ports of 1756-RM redundancy modules. It enables synchronized cross-loading between redundant ControlLogix processor racks. Industrial plants use this optical link to prevent process interruptions. Each assembly delivers exact optical cable specifications for ControlLogix redundancy applications. Proper cable routing ensures clean communication across redundant chassis pairs.
