The GE IC695ALG112 is an isolated analog input module for the PACSystems RX3i series of Programmable Logic Controllers (PLCs), now part of Emerson Automation. It is specifically designed for applications that require a high degree of electrical isolation to ensure signal integrity and protect against electrical noise.
Key Features and Specifications
- Isolated Channels: The primary feature of the IC695ALG112 is its 6 channels of isolated analog input. This isolation is both channel-to-channel and channel-to-backplane, which is crucial for preventing ground loops and protecting the system from voltage surges and electrical interference common in industrial settings.
- Universal Input: Each of the six channels can be individually configured to accept a variety of voltage and current signals, including:
- Voltage: ±10V, 0-10V, ±5V, 0-5V, and 1-5V
- Current: 0-20mA, 4-20mA, and ±20mA
- High Resolution: The module has a 16-bit Analog-to-Digital Converter (ADC), providing high-precision readings for accurate data acquisition.
- Software Configurable: All configuration settings, such as input ranges, data format, and filtering options, are done using the Proficy Machine Edition software. This eliminates the need for physical jumpers or switches on the module.
- Advanced Diagnostics: The module includes on-board diagnostics for error-checking, open-wire detection for current inputs, and reporting of module faults and channel alarms.
- Hot Swap Capability: The IC695ALG112 supports hot insertion and extraction, allowing it to be replaced without powering down the entire system, thus minimizing downtime.
Applications
The IC695ALG112 is commonly used in industrial automation and process control applications where a high degree of electrical isolation and signal accuracy is required. It is ideal for:
- Process Control: Monitoring and controlling parameters like temperature, pressure, and flow in chemical plants, power generation facilities, and refineries.
- Critical Measurements: Used for applications where the integrity and accuracy of the analog signal are paramount, and protection from noise is a concern.
- Harsh Industrial Environments: Its isolation capability makes it suitable for use in environments with large motors, variable frequency drives (VFDs), or other sources of electromagnetic interference (EMI).
