It shares the same mounting, memory, and communications, making it a drop-in upgrade for applications needing more I/O racks."},{"question":"What series does the CS1G-CPU43H belong to?","answer":"It is part of the CS1G series from Omron."},{"question":"What package type is it?","answer":"Listed as Bulk packaging."},{"question":"Will the CS1G-CPU43H drop into a panel designed for the CS1G-CPU44H?","answer":"Yes, because they share the same backplane mounting, memory size, and communications ports. The only difference is the maximum expansion limit (30 modules for 43H vs 40 for 44H), so as long as the existing rack configuration does not exceed 30 modules, replacement is straightforward."},{"question":"What compliance certifications does it carry?","answer":"It is approved by CE, cULus, Lloyd, and NK (Nippon Kaiji Kyokai) for marine and industrial applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/omron/CS1G-CPU43H","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/CS1G-CPU43H when reusing this data.
