3BSE018526R1
Official Full Product Name & Function Description Full Official Name ABB DSAI 133N Safety Analog Input Board, Order Code: 3BSE018526R1, high-precision safety-rated analog input I/O card for ABB Advant Master / Advant OCS DCS control systemsABB Group. Core Function This rack-mounted safety analog input module acquires high-accuracy analog process signals from field transmitters and sensors, converts raw analog signals into digital data for Advant Master DCS controllers. It supports dual signal types (0–10 VDC voltage / 4–20 mA current), features SIL-capable safety signal isolation, built-in per-channel fault diagnostics, and galvanic separation between field circuits and internal backplane bus. It delivers 0.025% ultra-high measurement precision for critical process variables including pres
