DS3800NGRD

DS3800NGRD is a I/O Data Slave Board manufactured and designed by General Electrics. It is a part of the Mark IV Control System. In a gas turbine control system, an I/O (input/output) data slave board is a device that communicates with the main control system and manages the exchange of data between the control system and various sensors, actuators, and other devices in the turbine. The I/O data slave board acts as an interface between the control system and the physical components of the turbine, allowing the control system to monitor and control various parameters such as temperature, pressure, and speed. The board typically includes multiple input and output channels, each of which can be connected to a specific sensor or actuator. It also includes a microcontroller or other processing unit that manages the flow of data between the various channels and the main control system.

Features

• High-speed Communication: Communicate with the main control system and the various sensors and actuators at high speeds to ensure that data is transmitted quickly and accurately.
• Multiple input/output channels: Multiple input and output channels to accommodate the various sensors and actuators used in the gas turbine system. Compatibility with various sensors and actuators: Compatible with a wide range of sensors and actuators to ensure that it can be used in different types of gas turbine systems.
• Robustness: Designed to withstand the harsh operating conditions of a gas turbine system, including high temperatures, vibrations, and electromagnetic interference. Real-time processing: Process data in real-time to ensure that the gas turbine system operates safely and efficiently.
• Diagnostic capabilities: Diagnostic capabilities that allow it to identify and report any problems with the sensors, actuators, or other components of the gas turbine system.

Diagnostics

• A Mark IV annunciator drop is reserved to inform the operator of a diagnostic failure. The operator can enter the diagnostic alarm display through a soft switch on the alarm display to find the details of the failure. Off-line diagnostics consist of a series of operator initiated tests to verify input/output operations. Therefore, most of the off-line diagnostics can he used only when the turbine is not running. The exceptions are the tests on operator inputs and displays. An analog test module is required to implement tests 6 through 10 below. The following input/output areas are tested:
• Auxiliary display
• Operator's panel membrane switches
• Digital I/O cards
• Contact inputs
• Relay outputs
• Pulse rate inputs
• Vibration inputs
• Pressure inputs
• Thermocouple inputs
• Analog output card
