It accepts a 0.3 A max load from the 24 V power module or external supply (20.4–28.8 V). The front end carries 11 digital inputs (IEC 61131-2 type 1): 5 floating, plus 8 bidirectional non-floating DI/DO. Three of those can be parameterized as failsafe inputs, or six as isolated digital inputs. One differential analog input doubles as a supplementary digital input. PROFIBUS DP is the only fieldbus on board; there are zero PROFINET interfaces. If the design calls for PN, this isn't the control unit you want — it's a different order code in the family. Terminal capacity: signal lines 0.05–1.5 mm², AWG 30–16. Strip length isn't given, but usual practice with spring-cage (not confirmed) — verify against the mating connector datasheet. ## Mounting and derating Dimensions 191 × 73 × 75 mm (H×W×D), IP20 rated. Above 1 000 m altitude, derate 3 K per 1 000 m on the ambient temperature. Maximum power loss is 20 W. With V/f control without encoder supported (not vector with encoder), this control unit fits standard S120 drive configurations where encoderless vector or V/f is adequate. Conformal coating and extended temperature qualification (storage –40 to +70 °C) mean it's intended for the Siemens SIPLUS harsh-environment line, but it remains a standard catalog item. For the BOM, that's a clean MRO cross-reference: if you spec 6SL3040-1LA00-0AA0, this is the ruggedized swap with the same footprint and PROFIBUS connection. Available quoted to order via RFQ. No lead-time number here — quantity and schedule determine that. If you need a PCN or environmental compliance package (ISA/ANSI, IPC conformal coating, RoHS/REACH statements), they're part of the standard Siemens documentation for SIPLUS products; request them with the RFQ.","metaTitle":"Siemens 6AG1040-1LA00-2AA0 CU310-2 DP, -20…+55 °C","metaDescription":"SIPLUS S120 Control Unit, -20 to +55 °C, PROFIBUS, 1 AI / 11 DI, conformal coated.
