Product Details
Technical Overview
The AAI141-H50 is a high-density current input module optimized for the Yokogawa CENTUM VP and CS 3000 control systems. This unit supports 16 channels of 4 to 20 mA signals, specifically designed for applications where high-speed data acquisition is required across multiple loops. As an "H" suffix module, it features integrated HART digital communication, allowing the system to access diagnostic data from intelligent field transmitters without disrupting the analog signal.
The "S2" revision indicates enhanced reliability and updated hardware components to meet modern industrial standards. By utilizing a non-isolated architecture where all channels share a common ground, this module maximizes space efficiency within the I/O nest while providing an industry-leading 10 ms update cycle for real-time process monitoring.
