Product Description
The DS200DMCBG2AKG is a IOS DUP Processor board that exists as a member of a EX2000 legacy series. This is considered a legacy series product as it has been discontinued for mass production in the years since its original manufacturing. With this being said, here at AX Control we make a concerted effort to keep both new and refurbished automated industrial products in our inventory for your every convenience. This model of IOS DUP Processor Board is a modified version of the parent PCB DS200DMCBG2; possessing a functional revision 1 rated at an "A," a functional revision 2 rated at a "K", and an artwork revision rated at a "G".
Hardware Tips and Specifications
As with any EX2000 series model, a series of hardware details and specifications are important to consider before making a final purchase decision. The GE IOS DUP Processor Board DS200DMCBG2AKG contains three 26-pin connectors, one 40-pin connector, and 19 jumpers. The board also has 2 LEDs. One RS-232 port is available affixed to the base board of the DS200DMCBG2AKG, for serial communication accessibility purposes.This GE IOS DUP Processor Board also features a Restart button, useful if the DS200DMCBG2AKG shows signs of intermittent processing errors or other functional problems. Only a qualified servicer should access the rack with the power on in the drive due to the potentially lethal current residing on the surface of this printed circuit board.
Beyond all of those aforementioned hardware specifications, it is important to mention the DS200DMCBG2AKG PCB's specific PCB coating style. This DMCB-abbreviated board's coating style can be defined as normal-style PCB coating. Normal PCB coating is not as complete or extensive in its circuit board coverage as the alternative Conformal-style PCB coating. While this is true, the normal PCB coating present on the base board of this DS200DMCBG2AKG circuit base board is much thicker than its conformal-style coating competition. The normal coating style specific to this DS200DMCBG2AKG printed circuit board was discovered through an analysis of its individualized part number. As described in the "DS200DMCBG2AKG Part Number Breakdown" embedded in the manuals tab above, the "G2" portion of the DMCB IOS DUP Processor board designates it both as a EX2000 series group 2 member as well as a normally-coated board.
Troubleshooting Tips and Specifications
A Series of instructions and best practices have been made apparent by the DS200DMCBG2AKG's manufacturers, for both efficient and safe installation and function troubleshooting. These best practices are oftentimes presented in a series of steps in original manufacturer manuals, to outline the process clearly and effectively.
A first step in safe and efficient fault troubleshooting involves, rather obviously, locating and accessing the DMCB board in the board rack. After this is done, the drive replacer should use one finger to press the Restart button and hold down the button for five seconds to give all the power in the board an opportunity to exit the board from its respective rack. Some components temporarily store power, but after a few seconds, the existing electricity exits the board. When you release the Restart button, the board begins a restart sequence and initiates normal processing. Releasing all surface voltage from the face of the DS200DMCBG2AKG is important, as potentially lethal voltages may be present on similar PCB versions.
The second troubleshooting step may only be performed when power is disconnected from the entirety of the overall drive assembly. With the power removed from the drive, examine the two fuses on the board and check to see if one or both of them have blown. If the fuses are blown, the element in the fuse will have broken which causes the circuit to stop functioning. This protects the board from damage when a power surge or other condition occurs and too much voltage is present in the board. If a fuse is blown, it becomes necessary to replace it with an new fuse with the same rating. A fuse with a different rating might damage the board if a power surge enables more voltage to be present in the board and the voltage damages components. Please make an effort to remember that this DS200DMCBG2AKG model features three total revisions inclduing a significant artwork revision, which may slightly alter nominal and safe installation practices.
