The 7SR511 comes in several hardware configurations (market-facing numbers), such as , 7SR5111-1AA21-0AA0 , and 7SR5111-3AA16-0AA0 . These configurations vary in the number of binary inputs/outputs, size (S6 or S12 enclosure), and communication interfaces, but all share a common foundation of protection functionality.
