DS3800NGRC1H1G | Mark IV General Purpose Remote Controller Module

Description

Product Introduction

The DS3800NGRC1H1G is the deep-space hardened version of the general-purpose remote controller with nuclear-grade environmental protection—the NGRC built for installations where radiation tolerance and the highest level of environmental protection are both required. 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. The second “1” adds enhanced diagnostic features. The final “G” is the nuclear-grade environmental package: triple-layer conformal coating with ceramic-reinforced topcoat, hermetically sealed components, and extended temperature range. This board was designed for the most extreme radiation environments where the highest level of protection is 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. Compare this to the NGRC1H1F (same deep-space hardening, but with military-grade environmental package). The 1H1G adds a ceramic-reinforced topcoat and extended temperature range for the most extreme environments.

Frequently Asked Questions (FAQ)

What makes the “G” suffix different from the “F”?
The “G” adds a ceramic-reinforced topcoat to the conformal coating. The “F” has a standard urethane topcoat without ceramic reinforcement. The ceramic-reinforced topcoat provides better abrasion resistance and slightly improved salt-spray protection. The “G” is for installations where mechanical abrasion or maintenance contact is a concern; the “F” is for standard harsh environments.

What’s the ceramic-reinforced topcoat?
The third layer of conformal coating contains ceramic micro-particles that resist scratching and abrasion. This protects the board during maintenance in tight cabinets where tools or cable bundles might contact the PCB. The ceramic topcoat also provides slightly better salt-spray resistance.

What’s the difference between the NGRC1H1G and the NGRC1H1F?
The 1H1G has a ceramic-reinforced topcoat; the 1H1F has a standard urethane topcoat. The deep-space hardening, enhanced diagnostics, and radiation event logging are the same on both boards. The 1H1G is for installations where mechanical abrasion is a concern; the 1H1F is for standard deep-space or nuclear 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 NGRC configured?
The NGRC is configured via jumpers on the board or through firmware settings. If you’re replacing a failed NGRC, photograph the jumper settings before removing the old board.

Can I hot-swap this board?
No. Mark IV backplanes are not hot-swappable. The 1H1G has 6 securing screws—make sure they’re all properly engaged before powering up.

What’s your warranty and lead time?
We stock the NGRC1H1G 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, a thermal cycle (-55°C to +85°C), 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.
