The GE IS230TNIDH4A is a DIN rail-mounted isolated contact input module for the GE Mark VIe control system. This module is a component of a larger assembly and serves as the physical interface for connecting on/off (binary) signals from field devices, while providing electrical isolation.
Key Features
- Isolated Contact Input: The module’s primary function is to handle binary (on/off) signals while providing electrical isolation. This protects the control system from ground loops, electrical noise, and high voltage spikes from the field devices. The “I” in “TNID” signifies “Isolated.”
- DIN Rail Mounting: The module is designed for standardized installation on a DIN rail, which is a common practice in industrial control cabinets. This simplifies wiring, saves space, and makes the system modular and easy to maintain.
- I/O Module: This is the core electronic component of the I/O assembly. It contains the circuitry that processes and conditions signals from the field. It works in conjunction with a terminal board where the field wiring is terminated.
- Mark VIe Integration: As part of the IS230 series, this module is a key component of the Mark VIe control platform, which is widely used for controlling turbines in power generation and other heavy industries.
Applications
The IS230TNIDH4A is used in a wide range of industrial settings to provide a reliable and organized interface for discrete signals, particularly in environments with significant electrical noise or voltage differences.
- Power Generation: It is used in power plants to monitor the status of various devices on gas and steam turbines, such as valve limit switches, motor run/stop indicators, and pressure switches, while protecting the control system from electrical interference.
- Industrial Automation: The module is a fundamental building block in many manufacturing processes that rely on automated control for efficiency and safety. The isolation feature is particularly useful in large facilities with extensive wiring, where ground loop issues can be common.
