The SCM5B, SCM7B, and SensorLex® 8B signal conditioning modules from Dataforth (Tucson, AZ) are all fully encapsulated, making them corrosion-resistant and well suited for use in rugged environments like wind turbines.
The performance isolated analog I/O signal conditioning modules condition and protect critical data acquisition and control signals, as well as sensitive connected equipment. Miniature digital I/O modules create a rugged, protective isolation barrier, effective to 4kV, between the field and the computer system.
The signal conditioners provide ±0.03 to 0.05% accuracy, better than six sigma reliability, low output noise, high surge withstand, and an operating temperature range of -40°C to 85°C. The conditioners feature 240VAC continuous input protection, 1500Vrms transformer isolation, and ANSI/IEEE C37.90.1 transient protection. Secondary protection against lightning strikes and other overvoltage events is also provided.
In Dataforth's application note "Wind Turbines Today," the main components pivotal to wind turbine technology are broken down and explained, and more information about their signal conditioners is provided.
