The Lenze AMS 304i-120 is a compact analogue input module designed for industrial automation systems within the Lenze AMS I/O family. It provides four current input channels, enabling precise measurement of analogue signals commonly used in process control and sensor interfacing. With a 12-bit resolution, this module ensures accurate data acquisition for demanding applications. Each channel can be individually configured for either 0-20 mA or 4-20 mA input ranges, offering flexibility for various sensor types and measurement tasks. The module features 2-wire connection technology for simplified wiring and includes potential isolation between the channels and the backplane bus, enhancing system reliability and signal integrity. Its fast conversion time allows for responsive monitoring of dynamic processes.
