DS3800NGRA1H1C | Replacement for DS3800NGRA

Description

Product Introduction

The DS3800NGRA1H1C is the ultimate general-purpose remote adapter—combining deep-space hardened components with dual-layer UV-resistant conformal coating for the most extreme environments. The suffix tells the story: the first “1” indicates a hardware revision with improved signal conditioning. The “H” specifies deep-space hardened components rated for 10 Mrad total dose, heavy ion tolerance, and solar flare event logging—with an additional radiation-hardened coating. 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 radiation tolerance, humidity protection, and UV resistance are all required.

The deep-space hardened components (10 Mrad total dose, heavy ion tolerance, solar flare event logging) ensure the board survives in environments that destroy even nuclear-hardened boards. The dual-layer conformal coating with UV protection ensures the board survives in outdoor, coastal, or UV-exposed environments. Compare this to the NGRA1G1B (same deep-space hardening and diagnostics, but single-layer coating without UV protection). The 1H1C adds UV resistance and better humidity protection.

Frequently Asked Questions (FAQ)

What’s the difference between the NGRA1H1C and the NGRA1G1B?
The 1H1C has a dual-layer conformal coating with UV-resistant topcoat. The 1G1B has a single-layer coating without UV protection. The deep-space hardening, enhanced diagnostics, and radiation event logging are the same on both boards. The 1H1C is for installations where UV exposure is a concern; the 1G1B is for standard indoor environments.

What’s the dual-layer conformal coating?
The first layer is a standard acrylic conformal coating. The second layer is a UV-resistant topcoat that prevents the acrylic from yellowing or cracking after years of exposure to sunlight or UV-emitting light sources. This is particularly important for outdoor enclosures, cabinets with windows, or installations with UV-emitting lamps.

What’s the difference between the “H” and “G” suffix?
The “H” and “G” suffixes both indicate deep-space hardened components (10 Mrad, heavy ion tolerance, solar flare logging). The “H” version includes a radiation-hardened coating over the ASIC, providing additional protection against radiation-induced damage. The “G” version does not have this coating. The “H” is for the most extreme radiation environments.

What’s the radiation tolerance of this board?
The board is rated for 10 Mrad total ionizing dose, heavy ion LET >100 MeV·cm²/mg, and solar flare tolerance. The components are latch-up protected and SEE immune. The board also includes MIL-STD-461G EMP protection.

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

How is the NGRA configured?
The NGRA is configured via jumpers on the board or through firmware settings. If you’re replacing a failed NGRA, photograph the jumper settings before removing the old board.

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 NGRA1H1C in limited quantities. Lead time is 2-3 business days. We offer a 2-year warranty. We test every board with a 48-hour burn-in and a full 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.
