Product Overview

• Part No: DSAI130D, full part number 3BSE003127R1
• Brand: ABB
• Series: Advant OCS / S100 I/O module, compatible with 800xA / AC800M DCS platform
• Type: Isolated differential analog input acquisition module

• FunctionConvert analog current and voltage signals from field transmitters, temperature, pressure, flow and liquid level sensors into digital data. Transmit collected signals to DCS main controllers for closed-loop regulation, real-time monitoring, trend recording and interlock protection. Differential wiring greatly eliminates on-site electromagnetic interference, stable for power, chemical and metallurgy strong interference workshops.
