DS3800HMAC1H1F

Product Description

The DS3800HMAC1H1F is a media access board.  This is one of several media access boards for the Mark IV system available within AX Control stock.  The Mark IV Speedtronic system, like earlier Speedtronic systems,  is designed to manage and control gas and steam turbine systems.  Unlike earlier systems, the Mark IV offers triple modular redundant control that uses microprocessors to vote on each system control using independent and identical processors. 

The DS3800HMAC1H1F board weighs in at approximately 0.98 pounds.  The rectangular-shaped board is marked with the board ID and with several codes that will assist with wiring and location.   Each corner is factory drilled.  The edges are marked with alphanumeric codes and arrows to assist with alignment.  

The largest component on the DS3800HMAC1H1F is a red metal vertical component (206B3334G1).  This is connected to the main PCB using two screws.  The component carries four coaxial components that are surface wired to the board from its rear edge.   The board also carries other connectors like a right-angled stab-on connector, a right-angled pin connector, and a right-angled cable connector. 

Other board components include relays, transistors, integrated circuits, and LED indicators.  The board has several TP test points as well as several jumper switches.  Jumpers are used to configure the board as needed by the end-user. 

Installation and handling guidelines for this particular component or for the Mark IV system, in general, can be found through original GE documentation.  If you do not have access to your original GE manuals or user guides, we may be able to help with replacements.
