Overview

The IMASI13 Analog Input Module is a Harmony rack I/O module within the Symphony Enterprise Management and Control System. It offers 16 analog input channels designed to interface with isolated thermocouples, millivolt, RTD, and high-level analog signals. These signals are converted to digital values with 24-bit resolution. Each channel has an independent analog-to-digital converter (ADC) and can be independently configured to handle various input types. The module allows controllers to monitor and control industrial processes efficiently.
