Overview
The IMASI23 Analog Input Module is a component of the Harmony rack I/O system, integrated within the Symphony Enterprise Management and Control System. It features 16 analog input channels capable of interfacing with isolated thermocouples, millivolt signals, RTDs, and high-level analog signals. Each channel is equipped with its own 24-bit analog-to-digital converter, allowing for precise data conversion. Channels can be individually configured to accommodate different input types. This module enables a controller to accurately monitor and control processes by converting and processing analog signals.Specifications
