GE IS200VRIDG1A VME RACK ID DONGLE

الوصف

The GE IS200VRIDG1A is a VME Rack ID Dongle for the Mark VI series of GE’s Speedtronic Gas Turbine Control Systems. It is a small but critical passive component used to uniquely identify each VME rack in a control system.

Key Features and Functionality

The VRIDG1A plays a simple yet vital role in a Mark VI system’s configuration and operation:

• Rack Identification: Its primary function is to provide a unique identifier for the VME rack it is installed in. When a new system is being configured, or when a rack is replaced, the VRIDG1A is used to set the rack ID. This allows the Mark VI controllers to correctly recognize and communicate with the I/O cards in that specific rack.
• Passive Component: The dongle is a passive device, meaning it contains no active electronics like a processor or memory. It typically uses a combination of jumpers or fixed wiring to represent a unique binary code. This design makes it highly reliable and resistant to failure.
• System Integrity: By providing a unique and fixed identity for each rack, the VRIDG1A helps ensure the integrity of the control system. It prevents the wrong I/O cards from being installed in the wrong racks, which could lead to critical control or safety errors.
• Physical Location: The dongle is typically a small circuit board that plugs into a dedicated slot on the VME backplane of the Mark VI rack.
