Decoded from the Rockwell Automation catalog-number structure. Series and firmware revision are printed on the product label, not encoded here. | ||
Intended Use | Built for high-availability redundant process control applications. Redundancy modules synchronize a primary and secondary ControlLogix chassis so a controller fault switches over without stopping the process, typical of water treatment, pharmaceutical, power and oil and gas installations where downtime is not acceptable. | ||
