الوصف
The GE IC695ALG626 is a Thermocouple Input Module for the PACSystems RX3i series of Programmable Logic Controllers (PLCs), now part of Emerson Automation. This module is specifically designed for high-resolution temperature measurement using a wide range of thermocouple types.
Key Features and Specifications
- Thermocouple-Specific Design: Unlike universal analog modules, the IC695ALG626 is dedicated to handling thermocouple inputs, which allows for specialized features and higher accuracy in temperature measurement. It has 12 input channels that can be configured for any of the supported thermocouple types.
- Wide Thermocouple Support: It is compatible with a comprehensive list of thermocouple types, including B, C, E, J, K, N, R, S, and T. This versatility makes it suitable for a broad range of industrial applications.
- Cold Junction Compensation (CJC): The module has two dedicated on-board CJC channels that ensure accurate temperature readings by compensating for the temperature at the point where the thermocouple wires connect to the module’s terminals.
- High Resolution: The module features a 24-bit Analog-to-Digital Converter (ADC), providing high precision for temperature readings.
- Software Configurable: All settings, including thermocouple type, filtering, and open-thermocouple detection, are configured using Proficy Machine Edition software.
- Hot Swap Capability: This module supports hot insertion and extraction, which means it can be replaced while the system is powered on, minimizing downtime.
Applications
The IC695ALG626 is primarily used in industrial automation and process control systems where accurate and reliable temperature monitoring is critical. Common applications include:
- Power Generation: Monitoring turbine and generator temperatures.
- Chemical and Petrochemical: Controlling temperature in reactors, distillation columns, and other processes.
- Oven and Furnace Control: Regulating temperatures in industrial heating applications.
- Manufacturing: For any process requiring the monitoring of temperatures from -270°C to 1820°C depending on the thermocouple type.
