ABB SPASI23 Symphony Plus 16-Channel Universal Galvanically Isolated Analog Input Module (Bailey Infi 90 / Harmony DCS Series)

ABB SPASI23 Symphony Plus 16-Channel Universal Galvanically Isolated Analog Input Module (Bailey Infi 90 / Harmony DCS Series) Alias Factory ID: ASI23 Symphony Plus I/O Card Core Function Core Function SPASI23 is a rack-mounted universal analog input I/O card exclusively built for ABB Symphony distributed control systems. It collects multi-type analog sensor signals from field process equipment, performs signal conditioning, galvanic isolation, high-resolution A/D conversion, and transmits standardized digital data to the Symphony controller backplane via Controlway dual redundant RS485 bus. Supports independent software configuration for each of its 16 channels without hardware modification Eliminates ground loop interference via channel-to-backplane 1500 Vrms isolation Embeds linearizati
