The Yokogawa AMN11 is a Signal Conditioner / Isolator Module from the UTAdvanced series (also known as the UT55A series). It is specifically designed as a current-to-voltage converter.<br />
Its primary function is to accept a standard DC current input signal (most commonly 4-20 mA DC) and convert it into a proportional, electrically isolated DC voltage output signal (e.g., 1-5V DC). This type of signal conversion is essential for interfacing devices that use different signal standards within a control system.
