DS200CDBAG1A is a Contactor Driver Board developed by GE. It is a part of Driver Control control system. The component provides power to the Power Supply Board or DC Power Supply and Instrumentation Board to open and close a contactor . The coil voltages of the contactors range from 30 to 40 V dc. The module closes a contactor by applying 105 V dc for 250 msec to force the contactor closed. To keep the contactor closed, the board regulates the contactor drive current at the level set using pot RV1. Three test points, a fuse, wiring connectors, configurable jumpers, an LED indicator, and a potentiometer are included on this component. These features give the user a lot of control and enable application-specific customization. The pot allows users to control the current of the contactor driver. Jumpers are used to select coordinated operations. Users can check voltage signals using test points. This board transmits and receives output signals via three plug connectors and a terminal board. More information about connector location can be found in associated manuals. This board includes a potentiometer for adjusting the contactor driver current. This is typically set to 1.5 amps.
- When replacing the board, set pot RV1 on the new (replacement) board to the same position as on the replaced board. Failure to adjust the pot on DS304-type contactors may cause the contactor coil to fail. Testpoints are all referenced at CDBA common (ACOM), which is not the same as drive common. As a result, all test measurements must be carried out using isolated test equipment capable of measuring floating potentials.
- When the coordinated operation is chosen, an LED displays the status of the local contact close command.
- The input power is fused by FU1 and used to power the board from 75 to 140 V ac/dc. The coil voltages of the contactors must be between 30 and 40 V dc.
- It connects the drive control to a high-speed contactor, allowing for quick dropout protection in the drives.
- There are three testpoints. The testpoints allow the REFA voltage signal +15 V DC power supply to be checked. Three test points, a fuse, wiring connectors, configurable jumpers, an LED indicator, and a potentiometer are included on this Board.
- These features give the user a lot of control over the product and enable application-specific customization. The pot allows users to control the current of the contactor driver. Jumpers are used to select coordinated operations. Users can check voltage signals using test points. More information on these devices, including information on the board's protective fuse, can be found in the associated manuals. Regardless, the versatility of this board makes it a highly desirable and well-designed PCB.
- The board has two Berg-type jumpers labeled.TP1 and J2, as well as one adjustable pot labeled RV1.
- The jumpers are used for manufacturing testing or to provide customer options. The contactor dive current is set using Pot RV1. Pot RV1 is commonly used to control the contactor drive current at 1.5 A.
- The contactor drive current for DS304-type contactors must be set to 0.75 A.
On board fuse
- The component has a protective fuse FU1 on the board's 115 V ac input power. FU1 is a slow-blowing 4 A, 125 V, 2AG fuse. If FU1 continues to blow, the CDBA board is most likely faulty and should be replaced.
- Power Supply: A power supply unit to convert AC voltage to low voltage DC.
- Relays: To control the electrical power supply to different devices.
- Microcontroller: A microcontroller is the central processing unit of the driver board, responsible for managing the input and output signals.
- Input Interfaces: The board includes various input interfaces such as digital input pins, analog input pins, and UART, I2C, or SPI communication interfaces.
- Output Interfaces: The board includes various output interfaces such as digital output pins, PWM output pins, and UART, I2C, or SPI communication interfaces.
- Protection Circuits: Protection circuits protect the board and connected devices from over-current, over-voltage, and short-circuits.
- LED Indicators: LED indicators indicate the status of the board and connected devices.
- Expansion Capabilities: The board may include expansion slots to connect additional peripheral devices or sensors.
- Programming Interface: The board includes a programming interface to upload firmware or software onto the microcontroller.
- Operating Temperature: The operating temperature range for the contractor driver board may vary based on the manufacturer and specific model.
- Board Hardware: Made up of wiring connectors (terminal boards and plug connectors), a potentiometer, two programmable jumpers, an LED indication, three test points, and a fuse. The paragraphs that follow in this section provide descriptions of these products.
- Potentiometer: Include an adjustable pot for setting the contactor driver current.
- Configurable Jumpers: One programmable jumper for factory test selection is present on every G1A generation. The boards from revision G1BBA forward have two programmable jumpers for synchronized operation selection and factory test selection.
- Hardware jumpers or switches may be implemented on supported ARCNET controller boards for hardware configuration.
- Each of these boards retains the ability to configure the dual-ported memory base address, I/O base address, ARCNET address of the PC, and interrupt request level (IRQ). Other card-specific features are available.
