DS3800NGRD | New Surplus GE Turbine Control Board

Description

Product Introduction

The DS3800NGRD is a general-purpose remote device interface board for Mark IV systems—the “G” in the suffix indicates general-purpose functionality, the “R” indicates remote, and the “D” indicates device. This board was used in distributed control applications where remote devices needed to be interfaced with the Mark IV system. It provides flexible, configurable remote device connectivity that can be adapted to different applications.

The board plugs into the Mark IV backplane and provides a configurable remote device interface. It’s more flexible than the dedicated remote I/O boards, but that flexibility comes with more configuration effort. Compare this to the DS3800NGRC (remote controller) or the DS3800NGRA (remote adapter). The NGRD is a remote device interface—it’s specifically designed for remote device connectivity where the standard boards don’t fit the configuration.

Frequently Asked Questions (FAQ)

What does the NGRD board do?
The NGRD is a general-purpose remote device interface board for Mark IV systems. It provides flexible, configurable remote device connectivity for distributed control applications.

What’s the difference between the NGRD and the NGRC?
The NGRD is a remote device interface—it provides connectivity for remote devices. The NGRC is a remote controller—it provides control and monitoring capabilities. The NGRD is typically used for device connectivity; the NGRC is used for control applications.

How is the NGRD configured?
The NGRD is configured via jumpers on the board or through firmware settings. Check your system documentation for the specific configuration requirements. If you’re replacing a failed NGRD, 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 the most common failure mode on the NGRD?
We’ve serviced about a dozen NGRD boards. The most common failure is the edge connector—corrosion from humidity. The second most common failure is the device interface circuitry—it can degrade over time. The board is repairable.

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