The IMASI23 Analog Input Module is a Harmony rack I/O module designed for the Symphony Enterprise Management and Control System. It provides 16 analog input channels that interface isolated thermocouple, millivolt, RTD, and high-level analog signals to a controller, featuring an analog-to-digital conversion resolution of 24 bits.
Each channel includes its own analog-to-digital converter and can be independently configured to handle the required input type. These analog inputs are used by a controller to monitor and control industrial processes.
The module is suitable for applications where high-precision analog monitoring is required, allowing each channel to operate independently and reliably. It ensures accurate signal conversion and provides the necessary interface for controllers to make informed process decisions.
The IMASI23 can serve as a direct replacement for the IMASI03 or IMASI13 modules with only minor modifications. Adjustments to specification S11 in function code 216 are needed to account for differences in resolution options. Additionally, verification of power supply sizing and system current requirements may be necessary due to changes in power consumption.
