GE DS3800HLIA LOGIC INPUT CARD

Part Number DS3800HLIA Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockDS3800HLIA is a High Voltage Logic Input Isolator Board manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic Gas Turbine Control Systems. A high-voltage logic input isolator board is a piece of electronic hardware used to safely interface high-voltage signals with low-voltage logic circuits. It serves as a protective barrier to prevent voltage spikes or noise on the high-voltage side from damaging or interfering with the sensitive components on the low-voltage side.

Key features of a high voltage logic input isolator board may include: Isolation: The board uses isolation techniques, such as optocouplers or transformers, to electrically separate the high-voltage input from the low-voltage output. Voltage Level Shifting: It often includes components that shift the high voltage signal to a compatible logic level, typically from a higher voltage (e.g., 24V or 48V) to a lower voltage (e.g., 3.3V or 5V) suitable for microcontrollers or digital logic circuits.

Protection: High voltage inputs can be susceptible to transients, spikes, or noise. Isolator boards often include protective measures, such as voltage clamping or filtering, to ensure that these disturbances do not affect the low-voltage side. Galvanic Isolation: Galvanic isolation means that there is no direct electrical connection between the input and output sides. This is crucial for safety and to prevent ground loops.

Compatibility: These boards are designed to be compatible with standard digital interfaces like GPIO (General Purpose Input/Output) pins on microcontrollers or other digital devices. Signal Conditioning:In some cases, the isolator board may include signal conditioning features like amplification, inversion, or pulse shaping to ensure that the signal is correctly interpreted on the low-voltage side.
