The IMASI13 Analog Input Module is a Harmony rack I/O module that is part of the Symphony Enterprise Management and Control System. It has 16 analog input channels that interface isolated thermocouple, millivolt, RTD, and high level analog 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 to handle the desired input type. These analog inputs are used by a controller to monitor and control a process.
The IMASI13 module can be used as a direct replacement for the IMASI03 module with only minor modifications. Changes to specification S11 in function code 216 are required to handle the differences in resolution choices. Verification of power supply sizing calculations and system current requirements could be necessary because of the change in power consumption.
This instruction explains the IMASI13 module specifications and operation. It details the procedures necessary to complete setup, installation, maintenance, troubleshooting, and replacement of the module.
NOTE: The IMASI13 module is fully compatible with existing INFI 90® OPEN Strategic Enterprise Management Systems.
