Functional Description

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.

Features

  • 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.

Configurable Hardware

  • Within the board's hardware configuration, it include two Berg-type jumpers, TP1 and J2, as well as an adjustable potentiometer labeled RV1. The jumpers, TP1 and J2, serve multiple purposes, such as aiding in manufacturing testing and providing options for customers to tailor the board to their specific needs. Additionally, RV1, the adjustable potentiometer, plays a pivotal role in the system, primarily used to regulate the contactor drive current. Typically, RV1 is employed to finely control the contactor drive current, maintaining it at a level of 1.5 A.
  • For DS304-type contactors, a specific drive current of 0.75 A is recommended and can be configured accordingly. These configurable hardware elements empower users to adapt the board's settings to meet particular requirements, ensuring optimal performance and functionality.

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.

Product Attributes

  • Power Supply: The power supply unit in this context serves as the heart of the system, responsible for converting alternating current (AC) voltage from a power source into a stable and controlled low-voltage direct current (DC) output. This conversion is crucial for ensuring that various electronic components and devices receive the appropriate power they need to operate effectively.
  • Relays: Relays play a pivotal role in the control and distribution of electrical power within the system. They act as switches that enable or disable the power supply to different devices or components. By controlling the electrical flow, relays allow for precise management of various functions and enable the safe operation of connected devices.
  • Microcontroller: Responsible for managing and coordinating input and output signals, making real-time decisions, and executing programmed instructions. This intelligence enables the board to respond to external stimuli and operate devices according to predefined logic.
  • Input Interfaces: Input interfaces provide the means for the driver board to communicate with the external environment. These interfaces may include digital input pins, analog input pins, as well as universal asynchronous receiver-transmitter (UART), inter-integrated circuit (I2C), or serial peripheral interface (SPI) communication interfaces. They allow the board to receive data, commands, or sensor readings from various sources, facilitating interaction with the surrounding systems.
  • Output Interfaces: Output interfaces enable the driver board to communicate with and control external devices. These interfaces can encompass digital output pins, pulse-width modulation (PWM) output pins, and UART, I2C, or SPI communication interfaces. They enable the board to send signals, commands, or data to connected devices, facilitating the automation and coordination of tasks.
  • Protection Circuits: Protection circuits are vital safeguards incorporated into the driver board's design to ensure the safety and longevity of the board and the devices it controls. These circuits monitor for over-current, over-voltage, and short-circuit conditions, immediately taking action to prevent damage or malfunction. Protection circuits play a critical role in maintaining system reliability and preventing catastrophic failures.
  • LED Indicators: LED indicators offer a visual means of monitoring the status and performance of the driver board and the connected devices. They provide real-time feedback, indicating power status, operational modes, or error conditions. LED indicators enhance user-friendliness and simplify troubleshooting processes.
  • Expansion Capabilities: Many driver boards are designed with expansion capabilities, featuring slots or connectors to attach additional peripheral devices or sensors. These expansion options allow for system customization and scalability, accommodating the integration of new functionalities or the connection of specialized equipment as needed.
  • Programming Interface: The programming interface is a crucial component for updating and customizing the driver board's firmware or software. It provides a means to upload new code to the microcontroller, enabling system upgrades, feature enhancements, or bug fixes. This interface empowers users to adapt the board to changing requirements and optimize its performance.

  • 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 Configuration

Hardware configuration refers to the process of adjusting settings on hardware devices through physical components like jumpers or switches. Supported ARCNET controller boards typically incorporate these elements to facilitate hardware configuration.

These boards maintain the capability to configure various parameters such as:

  • Dual-Ported Memory Base Address: This setting determines the location in memory where the dual-ported memory, which allows simultaneous access by different devices, is mapped.
  • I/O Base Address: Specifies the base address in the input/output range where the controller board communicates with other devices or the CPU.
  • ARCNET Address of the PC: This address uniquely identifies the PC within the ARCNET network, allowing it to send and receive data to and from other devices on the network.
  • Interrupt Request Level (IRQ): Defines the interrupt line used by the controller to signal the CPU for attention or action. It's crucial for managing hardware interrupts and ensuring proper communication between devices.
