Control & HMI General Electric

The General Electric DS3800NCCB1H1F Circuit Board is an essential component of the Speedtronic Mark IV series for turbine control. This auxiliary circuit board is meticulously designed and manufactured by General Electric to ensure maximum reliability and precise control of turbine operations.Covering much of the DS3800NCCB1H1F board are a number of resistors in various colors and patterns. The resistors are covered in colored bands which indicate the resistance capacity of each resistor. Several black diodes are grouped together in various places around the board. Many yellow capacitors of all different sizes can also be seen on the DS3800NCCB1H1F. The DS3800NCCB1H1F has 18 integrated circuits. Contained on each integrated circuit are very small parts such as diodes, capacitors, and resistors among other parts. The DS3800NCCB1H1F also features 4 resistor networks. Inside each resistor network is a group of resistors. Adding up the total resistance of all the resistors inside gives you the total resistance of each resistor network. On one side of the DS3800NCCB1H1F are 4 light-emitting diodes. These particular diodes, or LEDs, emit an orange light when they are functioning. Between the LEDs, there is a group of 15 test points. Testing the board using these test points helps to ensure that the board is working properly. A connector port is located on one edge of the DS3800NCCB1H1F board. Situated in the center of the DS3800NCCB1H1F is a separate connector port which is also used to connect parts to the board.Each product from AX Control is shipped packaged in an anti-static bag which dissipates all static energy that may accumulate during shipping.

The General Electric DS3820MAUD1A1B is a critical PCB/HMI component designed for the robust Mark IV series of control systems, which are used to manage gas and steam turbines. As a Freeway Media Access Module within the Directo-Matic Plus Control System, this unit is built on integrated microcomputers, ensuring maximum reliability and minimal downtime through intentional backups.The DS3820MAUD1A1B features a front panel clearly labeled 'General Electric Directo-Matic Plus Control System Freeway Media Access Module.' The panel integrates seamlessly with the underlying DS3800HMAC printed circuit board and includes three cutouts for viewing status LEDs: 'Cable A OK,' 'Cable B OK,' and 'Watch Dog Timer OK,' allowing for quick diagnostics. Connectivity is provided by four cable connectors (JB, JC, JD, and JE) for Cable A and Cable B, ensuring secure integration into the control system's communication pathways.Beneath the HMI panel, the PCB contains six LEDs, six test points (RXA, RXB, RCFG, DCOM, OXMIT, and 1RCV), and ten jumpers for system configuration. It is also populated with two transistors and forty circuits, including key components like J-K negative edge-triggered flip-flops, oscillating chips, and hex buffers. The HMI and PCB are securely connected by screws and nylon clips, ensuring a durable assembly. The DS3820MAUD1A1B is a high-quality component supported by GE technical assistance, making it an ideal choice for maintaining and upgrading critical turbine control systems.
