It is specified as a Safety Integrity Level 2 device, which is what decides whether this slot belongs in the safety portion of the loop or the standard one — integrators read that rating before they wire, not after. The function line itself reads Safety. 4SAI, 4 SIL2/SIL3, 4..20mA input 14bit, 24VDC, which is the short form the configurator uses when matching the module against the I/O list. ## Panel reality: indoor slot, not a wet-well box Housing is rated IP20, which means the module belongs inside a sealed enclosure — a panel, a cabinet, a control room — and it will not survive a hose-down, a wet well, or a digester headspace on its own. For a pump-station retrofit, the AI581-S sits inside the existing MCC or PLC cabinet and reads the 4-20 mA process signals already brought back from the field; the cabinet, not the module, is what keeps the H2S off the board. ## Compliance paperwork on file RoHS per EU Directive 2011/65/EU and Amendment 2015/863 July 22, 2019; REACH declaration dated 20241206 flags substances above 0.1 mass percent; Germany-issued SCIP entry 39206d4d-27ae-4fea-9f02-188f1f9f43e2. Customs classification carries CN8 85389091, the HS code a broker or parallel-import desk needs for the entry summary. ## What it is not: a terminal base or a 16-channel standard AI The 1SAP250300R0001 AI523 is a 16-channel non-safety analog input at 13-bit resolution covering U, I, RTD and DI; it carries more channels but no SIL rating, so it is not a safety substitute for the AI581-S.","metaTitle":"ABB 1SAP282000R0001 AI581-S, 4 SAI, SIL2/SIL3, 24VDC","metaDescription":"ABB 1SAP282000R0001 AI581-S safety analog input module, 4 channels, 4-20 mA at 14-bit, SIL2, 24 VDC, active in production, sourced to order against an RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":[],"specifications":{"CN8":"85389091","Function":"Safety. 4SAI, 4 SIL2/SIL3, 4..20mA input 14bit, 24VDC","Resolution":"Analog Input 14 bit","Analog Inputs":"4","WEEE Category":"5.
