The 12 digital inputs handle sensor or switch signals at 24 V DC, which is the standard control voltage for industrial panels. The 6 relay outputs give you isolated dry contacts for driving contactors, solenoid valves, or indicator lamps — no need for external interposing relays on smaller loads. The 24 V DC supply rail is shared with the input side, so one panel power supply feeds both the logic and the field wiring.","metaTitle":"ABB 1SVR440721R0300 CL-LMR.C18DC2 Logic Relay, 24 V DC, 12 D","metaDescription":"ABB 1SVR440721R0300 CL-LMR.C18DC2 logic relay, 24 V DC, 12 digital inputs and 6 relay outputs, DIN-rail mount.

The 1SVR440721R0300 is the 24 V DC version with 12 inputs and 6 relay outputs. A sibling with a different I/O mix or AC supply would require a different order code — no direct pin-compatible drop-in exists without checking the specific I/O and voltage requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/1SVR440721R0300","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/1SVR440721R0300 when reusing this data.
