DS3800NISA1C1C | New Surplus GE Turbine Control Board

Description

Product Introduction

The DS3800NISA1C1C is a premium version of the isolated serial adapter board—the NISA with extended temperature range, dual-layer UV-resistant coating, and enhanced diagnostics. The suffix tells the story: the first “1” indicates a hardware revision with improved isolation and signal conditioning. 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, and better diagnostic feedback were all required for isolated serial applications.

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 base DS3800NISA (standard temperature range, no diagnostics, no coating). The 1C1C gives you the same basic functionality with significant improvements in reliability and diagnostic capability.

Frequently Asked Questions (FAQ)

What’s the difference between the NISA1C1C and the base NISA?
The 1C1C adds enhanced diagnostics (configuration verification, serial link quality monitoring), extended temperature range (-40°C to +70°C vs 0 to 60°C), and dual-layer UV-resistant conformal coating. The base NISA has basic link status only.

What’s the “Serial Activity” LED?
The Serial Activity LED indicates traffic on the serial link. The board monitors the TX and RX lines. Green means data is flowing. Red means a communication error—check the serial device and 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 communication protocol for this board?
The communication protocol depends on the specific configuration. The NISA supports RS-232 and RS-485 depending on the jumper and component configuration. Check the board’s label or your system documentation for the exact protocol.

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 NISA1C1C 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.
