The GE IC695ALG628 is an RTD 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 Resistance Temperature Detectors (RTDs).
Key Features and Specifications
- RTD-Specific Design: This module is a dedicated solution for RTD-based temperature sensing, offering a high-density, high-accuracy interface. It provides 8 input channels that can be configured for various RTD types.
- Wide RTD Support: The IC695ALG628 is compatible with a wide range of RTD types, including 100Ω Platinum, 1000Ω Platinum, 120Ω Nickel, 10Ω Copper, and others. This makes it a versatile choice for many industrial applications.
- High Resolution: The module uses a 24-bit Analog-to-Digital Converter (ADC), providing exceptional accuracy and stability for temperature readings.
- Configuration: All settings, such as RTD type, filtering options, and wiring configuration (2, 3, or 4-wire), are configured using the Proficy Machine Edition software. This eliminates the need for physical jumpers or switches on the module.
- Advanced Diagnostics: The module provides on-board diagnostics for detecting open circuits, which is a common failure mode for RTD sensors. It can also report module faults and channel alarms.
- Hot Swap Capability: The module supports hot insertion and extraction, allowing it to be replaced while the system is powered on, thus minimizing downtime.
Applications
The IC695ALG628 is a crucial component in industrial automation and process control systems where accurate and reliable temperature monitoring is essential. Common applications include:
- Process Control: Monitoring and regulating temperatures in chemical reactors, food and beverage processing, and pharmaceutical manufacturing.
- Power Generation: For precise temperature measurement in turbines, generators, and heat exchangers.
- HVAC Systems: Used in industrial heating and cooling systems to ensure precise temperature control.
- Any application requiring precise temperature measurement with RTD sensors.
