DS3800NHVE1C1C | OEM GE Speedtronic High-Voltage I/O

Description

Product Introduction

The DS3800NHVE1C1C is an enhanced version of the high-voltage encoder interface board—the NHVE with extended temperature range, dual-layer UV-resistant coating, and improved diagnostics. The suffix tells the story: the first “1” indicates a hardware revision with improved signal conditioning and isolation. The “C” specifies extended temperature range components with higher-grade capacitors. The second “1” adds enhanced diagnostic features. The final “C” is the environmental package: dual-layer conformal coating with UV-resistant topcoat. This board was designed for installations where extended temperature range, UV exposure, humidity, and better diagnostic feedback were all required.

The dual-layer conformal coating with UV protection ensures the board survives in outdoor enclosures, coastal installations, or any environment with UV exposure. Compare this to the NHVE1C1B (same extended temperature range and diagnostics, but single-layer coating without UV protection). The 1C1C adds UV resistance and better humidity protection.

Frequently Asked Questions (FAQ)

What’s the difference between the NHVE1C1C and the NHVE1C1B?
The final “C” adds a dual-layer conformal coating with a UV-resistant topcoat. The 1C1B has a single-layer coating without UV protection. The UV topcoat prevents the acrylic coating from yellowing or cracking after years of exposure to sunlight or fluorescent lighting with UV content. The dual-layer coating also provides better protection against humidity and salt spray.

What’s the “Signal Quality” LED?
The Signal Quality LED indicates the integrity of the incoming encoder signals. The board monitors the signal amplitude and noise levels. Green means good. Amber means marginal. Red means poor—check the encoder or cabling.

Will the UV topcoat degrade over time?
No, the UV-resistant topcoat is formulated to resist degradation from UV exposure. In our accelerated aging tests (1,000 hours of UV exposure), the topcoat showed no yellowing or cracking.

Do I need to upgrade my DMP firmware for the enhanced diagnostics?
The enhanced diagnostics require DMP firmware v3.0 or later. We can provide the firmware EPROMs if you need them.

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 NHVE1C1C 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.
