The GE IS230SHRA2AG01 is a HART Analog I/O Assembly designed for the GE Mark VIe control system. It’s used to manage analog signals (e.g., 4-20mA) from field devices while also supporting the HART communication protocol. This module operates in a simplex configuration, meaning it’s a single, non-redundant unit.
Key Features
- HART Communication: This is a core feature that distinguishes it from a standard analog I/O module. HART (Highway Addressable Remote Transducer) is a protocol that allows a digital signal to be superimposed on the analog current loop. This enables the module to not only read the analog process variable (like temperature or pressure) but also to access additional digital information from a smart device, such as diagnostic data, calibration status, and device-specific parameters.
- Simplex Configuration: The term “simplex” indicates a single, non-redundant module. This is a cost-effective solution for applications where a failure of a single I/O point would not lead to a catastrophic event. It’s often used for non-critical monitoring or control loops.
- Analog I/O: The module handles both inputs (from sensors) and outputs (to actuators or valves), providing a versatile interface between the control system and the process.
- Mark VIe Integration: The IS230 series is a key part of the Mark VIe platform, ensuring seamless integration and compatibility with the main controller and other system components.
Applications
The IS230SHRA2AG01 is a valuable component in industrial settings where process data needs to be collected efficiently and with enhanced diagnostic information.
- Process Monitoring: It’s used in various industries to monitor process variables from smart transmitters, providing not only the primary measurement but also valuable health and diagnostic data from the instrument itself.
- Preventive Maintenance: The ability to access diagnostic information via HART allows for proactive maintenance. Engineers can remotely check the health of a transmitter, potentially identifying issues before they cause a failure.
- Control Systems: The module serves as a bridge for analog control loops, ensuring accurate signal transmission to maintain optimal process conditions.
