DS3800NGRC1H1F | GE Speedtronic General Purpose Remote Controller

Description

Product Introduction

The DS3800NGRC1H1F is the deep-space hardened version of the general-purpose remote controller—the NGRC built for installations where radiation tolerance goes beyond nuclear to deep-space extremes. 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 (LET >100 MeV·cm²/mg), and solar flare event logging. The second “1” adds enhanced diagnostic features. The final “F” is the nuclear-hardened environmental package: triple-layer conformal coating, EMP protection, and hermetically sealed components. This board was designed for the most extreme radiation environments—deep space missions, high-altitude platforms, or installations where standard boards would fail.

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 NGRC1F1F (nuclear-hardened, 1 Mrad, no heavy ion tolerance). The 1H1F gives you an order of magnitude more radiation tolerance—for customers who need the highest possible radiation tolerance for their remote control applications.

Frequently Asked Questions (FAQ)

What makes the “H” suffix different from the “F”?
The “H” adds deep-space hardening: 10 Mrad total dose versus 1 Mrad, heavy ion tolerance (LET >100 MeV·cm²/mg), and solar flare event logging. The “F” is nuclear-hardened; the “H” is deep-space hardened. The “H” is designed to survive deep-space radiation environments; the “F” is designed to survive nuclear environments.

What’s the heavy ion event LED?
The Heavy Ion Event LED indicates that the board has detected a heavy ion event—a galactic cosmic ray striking the board. Heavy ions can cause single-event effects in the FPGA and memory. The board logs heavy ion events and can recover from them. This is a feature of the “H” suffix—the “F” variant doesn’t have heavy ion detection.

What’s the solar flare event LED?
The Solar Flare Event LED indicates that the board has detected a solar flare event—a burst of radiation from the sun. The board logs solar flare events and can adjust its operating parameters to survive the event. This is a feature of the “H” suffix.

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 1H1F has 6 securing screws—make sure they’re all properly engaged before powering up.

What’s your warranty and lead time?
We stock the NGRC1H1F 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.
