1. Product Overview / Обзор продукта

The Woodward 8521-TC-SA is a high-precision Thermocouple Input Module designed for the distributed LinkNet I/O network. This module features 6 independent channels capable of interfacing with standard thermocouple types (such as J, K, R, S, T, and E) to provide accurate temperature data to Woodward MicroNet or Atlas controllers. With integrated cold junction compensation and advanced noise filtering, the 8521-TC-SA is essential for monitoring critical temperatures like Exhaust Gas Temperature (EGT) in turbine control and engine management systems. Its decentralized design reduces the need for long, expensive thermocouple extension wires.

Ключевое преимущество: Модуль 8521-TC-SA — это 6-канальный блок ввода термопар серии LinkNet. Он обеспечивает высокую точность измерения температуры и имеет встроенную компенсацию холодного спая. Модуль преобразует аналоговые сигналы от термопар в цифровой формат для систем управления Woodward, значительно упрощая кабельную разводку на объекте.
