DS3800HLNF MicroVax network controller card

Part Number DS3800HLNF Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockDS3800HLNF is a MicroVax Network Controller Card developed by GE. It is a part of Mark IV control system Features The board includes a backplane connector to allow the board to communicate with the larger rack system and its components. A right-angled connector near the board's front edge allows for the addition of another cabled connector. Prior to the Mark IV, most Speedtronic systems used terminal screw-type connectors; with the introduction of this system, connectors were changed to plug-in types to allow for faster component change-out. This front edge also includes extractor clips, which make it easier to pull the board from its location during replacement. FPGAs, integrated circuits, DIP switches, and other board components are present. Operator Interface Module To emphasize the commonality of control function, functional groups of switches, such as the operator selection switches and the EXECUTE switch, are color coded. Except for three switches, all switches in the 7 X 4 matrix communicate with [Cl via the HPIB card. The stop switch is located on the second row, far right, and communicates with.[R], [S], and [T] for increased reliability when initiating a normal shutdown sequence. And two (2) switches on the fourth row, far right, are linked to [RI, [Sl, and [Tl via the HPIB card. These are commonly used on compressor drives to manually raise and lower the speed/load setpoint. Normally, pressing the EXECUTE button prior to or during a raise/lower command is not required, but the EXECUTE feature is available if needed. If the Communicator [Cl fails, the stop and raise/lower buttons do not require pressing the EXECUTE button before initiating the command. Except for the voted pushbuttons, which are powered by a separate supply, the switch matrix is powered by the Communicator's 5V bus. To directly de-energize the fuel solenoids independent of the computers, a shrouded EMERGENCY STOP pushbutton has a contact wired in series with the master protective "4" relays in Relay Module l, [RELAYl]. The HAIC cards in [RI], [S], and [T] monitor the status of the EMERGENCY STOP pushbutton. All digital interface with the Operator Interface Module is provided by these cards and the HAIC card in [Cl]. The Video Display [CRT] is driven by the HVDB card in [C].CARD

About DS3800HLNFDS3800HLNF is the control card of Agger steam turbine. This component is a part of a series of Speedtronic control systems provided by General Electric Company since the late 1960s. However, Mark IV, of which the printed circuit board is a part, is the first system to provide a more complex turbine control system, in which redundant services using multiple control modules (TMR control) significantly reduce downtime and improve the overall efficiency of the control system.DS3800HLNF is a larger control card, which weighs about 1.15 pounds before adding external packaging. Because we use extra padding and packing materials to protect the parts during transportation, your transportation weight will be higher.The front edge of DS3800HLNF has two extraction clips to help pull the motherboard out of the rack system. The front edge also has two tabs so that the installer has a place to fix the circuit board when inserting the card in place. This not only improves the stability, but also protects the components at the front of the circuit board.The surface of DS3800HLNF includes three sets of DIP switches. It also has an LED indicator, as well as a resistor network array, resistors and many integrated circuits, including FPGAs. The rear edge of the board is equipped with an extended backplane connector with several gaps.
