Product Description
The Yokogawa AAP849-S00 is a high-density pulse-to-current signal conversion module designed for the CENTUM VP Integrated Control System. It converts high-frequency pulse train inputs into standardized 4–20 mA DC analog outputs, enabling seamless integration of frequency-based field instruments with analog control loops.
This module is ideal for interfacing devices such as flow meters, tachometers, and speed sensors, providing accurate real-time representation of rotational speed and flow rate. Support for dual-redundant system configurations ensures continuous operation in mission-critical applications. Built for harsh industrial environments, the AAP849-S00 delivers high accuracy across a wide operating temperature range, making it suitable for power generation and chemical processing facilities.
