NFAF135-S50 Yokogawa Frequency Input Module

FCN consists of a power supply module, CPU module, I/O module, and base module. NFAF135-S50  is one of the I/O modules inserted in FCN. The CPU module uses the process value from each I/O module to execute application programs and perform necessary control. Communication between the CPU module and each I/O module is performed via SB-BUS connected to the base module. The CPU module is connected to the user interface PC via Ethernet, and users can perform operation and monitoring on it. The upper system for wind power generation systems usually uses a supervisory control and data acquisition (SCADA) software package for operation and monitoring of the process. Yokogawa offers FAST/TOOLS as a SCADA software package, which supports more than one million I/O points and is suitable for operation and monitoring wind turbines distributed over a wide area.

NFAF135-S50 satisfies the demand for high accuracy and high reliability mainly in the wind power generation market, and has the following features.

Feature 1: Highly accurate measurement
Improved measurement accuracy achieved by reducing the influence of clock resolution on the accuracy by using frequency computation with the number of multiple pulses and accumulated time of their intervals
Highly accurate measurement in the low-frequency range required for wind power generation achieved by extending the frequency output update cycle when pulse intervals are long.

Feature 2: High reliability
Part selection and design considering derating.
Environment-resistant evaluation considering specification margins.
