Overview
The Emerson Ovation 1C31116G04 is a voltage input personality module with integrated temperature sensor for the Ovation Distributed Control System (DCS). This module is mainly used for cold junction compensation (CJC) of thermocouple signals, measuring the temperature of the terminal block through a built-in temperature sensor, and calculating the actual temperature by combining with the thermocouple voltage signal to solve measurement errors caused by temperature change of the reference end. The module functions as a key component in Ovation control systems, which are widely used in power generation and industrial automation applications.
Key Features
- 8 Analog Input Channels for voltage signal acquisition from field sensors
