ABB Bailey IMASI13 Infi-90 ANALOG INPUT MODULE

The IMASI13 Analog Input Module is a Harmony rack I/Omodule that is part of the Symphony Enterprise Managementand Control System. It has 16 analog input channels thatinterface isolated thermocouple, millivolt, RTD, and high levelanalog signals to a controller with an analog-to-digital conversion resolution of 24 bits. Each channel has its own analog-to-digital converter and can be independently configured tohandle the desired input type. These analog inputs are used bya controller to monitor and control a process.The IMASI13 module can be used as a direct replacement forthe IMASI03 module with only minor modifications. Changesto specification S11 in function code 216 are required tohandle the differences in resolution choices. Verification ofpower supply sizing calculations and system current requirements could be necessary because of the change in powerconsumption.This instruction explains the IMASI13 module specificationsand operation. It details the procedures necessary to completesetup, installation, maintenance, troubleshooting, andreplacement of the module.
