Description
Product Introduction
The DS3800NGRC1F1F is the nuclear-hardened version of the general-purpose remote controller—the NGRC built for installations where radiation tolerance and EMP protection are as important as control reliability. The suffix tells the story: the first “1” indicates a hardware revision with improved signal conditioning. The “F” specifies nuclear-hardened components rated for 1 Mrad total dose, neutron fluence tolerance, and MIL-STD-461G EMP protection. The second “1” adds enhanced diagnostic features. The final “F” is the nuclear-hardened environmental package: triple-layer conformal coating and hermetically sealed components. This board was designed for installations where the standard NGRC would fail—nuclear facilities, high-radiation environments, or critical infrastructure where EMP protection is required.
The nuclear-hardened components (1 Mrad total dose, neutron fluence tolerance) and EMP protection ensure the board survives in extreme environments. Compare this to the NGRC1D1D (military-grade, no radiation hardening, no EMP protection). The 1F1F is for customers who need the highest possible radiation tolerance and EMP protection for their remote control applications.

|---|---|---|
| DS3800NGRC1D1D | ⚠️ Software Compatible | Military-grade without radiation hardening or EMP protection. If you don’t need radiation tolerance, this is a cost-effective alternative. |
| DS3800NGRC1F | ⚠️ Software Compatible | Nuclear-hardened components without enhanced diagnostics. |
| DS3800NGRC1F1 | ⚠️ Software Compatible | Nuclear-hardened with diagnostics but single-layer coating without UV protection. |
| DS3800NGRC1F1F (this board) | ✅ Drop-in Replacement | No further compatibility notes. This is the board. |
| DS3800NGRA1F1F | ✅ Drop-in Replacement | Similar nuclear-hardened remote adapter—check configuration. |
Frequently Asked Questions (FAQ)
What makes the “F” suffix different from the “D”?
The “F” adds nuclear hardening—radiation-hardened components rated for 1 Mrad total dose, neutron fluence tolerance (10^12 n/cm²), and MIL-STD-461G EMP protection. The “D” has military-grade components but no radiation hardening or EMP protection. The “F” is designed to survive nuclear and high-radiation environments; the “D” is not.
What’s the radiation tolerance of this board?
The board is rated for 1 Mrad total ionizing dose and 10^12 n/cm² neutron fluence. The components are latch-up protected and SEE immune. The board also includes MIL-STD-461G EMP protection.
What’s the radiation event LED?
The Radiation Event LED indicates that the board has detected a radiation event. The board logs radiation events and can recover from radiation-induced single-event effects. This is a feature of the “F” suffix.
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 1F1F has additional securing clips—make sure they’re properly engaged before powering up.
What’s your warranty and lead time?
We stock the NGRC1F1F 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.
