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.

The IMASI13 Isolated Analog Input module processes up to 16 analog field inputs for a Harmony
controller. The controller utilizes function codes 215 (enhanced analog module definition), 216
(enhanced analog input definition), and 217 (enhanced calibration command) to configure and calibrate the module, and to configure and access the module input channels.

Each channel can be individually programmed for the following input types:
■ 4 to 20 milliampere.
■ –10 to +10 VDC.
■ –100 to +100 millivolt (DC)
