The GE IC695ALG306 is an isolated thermocouple input module for the PACSystems RX3i series of Programmable Logic Controllers (PLCs), now a part of Emerson Automation. This module is specifically designed for high-resolution temperature measurement using a wide variety of thermocouple types while providing robust electrical isolation.
Key Features and Specifications
- Thermocouple-Specific Design: The IC695ALG306 has 6 isolated input channels dedicated to thermocouple temperature sensing. This specialized design ensures high accuracy and stability.
- Wide Thermocouple Support: It is compatible with a comprehensive list of thermocouple types, including J, K, T, E, R, S, B, and N, making it versatile for a broad range of industrial applications.
- Electrical Isolation: A crucial feature of this module is its channel-to-channel and channel-to-backplane isolation. This protects the system from ground loops and electrical noise, which are common in industrial environments and can degrade signal quality.
- High Resolution: The module features a 24-bit Analog-to-Digital Converter (ADC), providing high precision for temperature readings.
- Cold Junction Compensation (CJC): The module includes on-board CJC channels to ensure accurate temperature readings by compensating for the temperature at the point where the thermocouple wires connect to the module’s terminals.
- Software Configurable: All settings, including thermocouple type, filtering, and open-thermocouple detection, are configured using the Proficy Machine Edition software.
Applications
The IC695ALG306 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.
- Any application requiring precise and reliable temperature measurement with thermocouples in an electrically noisy environment.
