DS3800NHVM1B1A | New Surplus GE Turbine Control Board

Description

Product Introduction

The DS3800NHVM1B1A is an enhanced version of the high-voltage measurement interface board—the NHVM with extended temperature range and improved diagnostics. The suffix tells the story: the first “1” indicates a hardware revision with improved isolation and signal conditioning. The “B” specifies extended temperature range components. The second “1” adds enhanced diagnostic features (configuration verification, measurement integrity monitoring). The final “A” is the standard environmental package (no conformal coating). This board was designed for installations where better diagnostic feedback and extended temperature range were needed for high-voltage measurement applications.

The extended temperature range means the board can operate in uninsulated shelters or outdoor cabinets. The enhanced diagnostics verify the board’s configuration and provide detailed status reporting on the measurement inputs. Compare this to the base DS3800NHVM (standard temperature range, basic diagnostics). The 1B1A gives you the same basic functionality with better diagnostic feedback and extended temperature tolerance.

Frequently Asked Questions (FAQ)

What’s the difference between the NHVM1B1A and the base NHVM?
The 1B1A adds enhanced diagnostics (configuration verification, measurement integrity monitoring) and extended temperature range (-40°C to +70°C vs 0 to 60°C). The base NHVM has basic link status and standard temperature range only.

What’s the “Measurement Status” LED?
The Measurement Status LED indicates the integrity of the high-voltage measurement inputs. The board monitors the measurement signal integrity, checking for noise, drift, or out-of-range conditions. Green means all measurements are valid. Amber means marginal—check the input signal. Red means invalid—check the sensor or wiring.

Do I need to upgrade my DMP firmware for the enhanced diagnostics?
The enhanced diagnostics require DMP firmware v3.0 or later. Older firmware won’t recognize the diagnostic registers. We can provide the firmware EPROMs if you need them.

Does this board have conformal coating?
No, the final “A” indicates no conformal coating. This is a bare board. If you need conformal coating for humidity protection, look for the NHVM1B1B or NHVM1B1C variants.

What’s the voltage rating of this board?
The voltage rating depends on the specific configuration. Check the board’s label or your system documentation for the exact voltage rating.

Can I hot-swap this board?
No. Mark IV backplanes are not hot-swappable. Power down the cabinet, lock out the breaker, and wait 60 seconds before removing or installing the board.

What’s your warranty and lead time?
We stock the NHVM1B1A in limited quantities. Lead time is 1-2 business days. We offer a 1-year warranty. We test every board with a 24-hour burn-in and a diagnostic verification. The test report is included.

Is this board compatible with the Mark VIe?
No. This board is for Mark IV systems only. The backplane architecture is different.
