The GE IS230SDIIH2A is a discrete input module for the GE Mark VIe control system. It’s an isolated contact input assembly that operates in a simplex, or non-redundant, configuration. This module is used to read binary, or on/off, signals from field devices, like switches or relay contacts, while providing electrical isolation to protect the control system’s electronics.
Key Features
- Isolated Contact Inputs: The module provides electrical isolation between the field wiring and the control system. This is crucial for preventing ground loops and protecting the sensitive internal electronics from high-voltage surges or electrical noise present in the industrial environment.
- Simplex Configuration: Operating in a simplex mode means there’s a single unit for each input point, without a backup. This is a common and cost-effective approach for applications where a failure of an input signal won’t lead to a catastrophic event.
- Discrete Inputs: The module handles binary signals, which represent a simple two-state condition (e.g., a limit switch is either open or closed, a push-button is either pressed or released). It acts as an interface that converts these physical states into a digital signal that the Mark VIe controller can understand.
- Mark VIe Integration: As part of the IS230 series, this module is designed to seamlessly integrate with the Mark VIe control platform, ensuring easy installation and configuration.
Applications
The IS230SDIIH2A is used in various industrial settings where reliable monitoring of on/off signals is required.
- Power Generation: It’s used in power plants to monitor the status of various devices on turbines, such as valve limit switches, motor run/stop indicators, and pressure switches.
- Oil and Gas: In refineries and offshore platforms, it helps monitor the open/closed status of valves, the status of pumps, and the state of emergency push-buttons.
- Industrial Automation: The module is a fundamental component in many manufacturing processes that rely on automated control for efficiency and safety.
