IS230TNTRHIC | GE Gas turbine module

Description

Board IS230TNCIH4C is marketed by General Electric as a Printed Circuit Board. There are a total of twenty-five metal oxide varistors on the board. Two three-pin female plug connectors also populate the IS230TNCIH4C board. Communication Types：UDH or IONet Functional Acronym/Abbreviation：TNCI Humidity：5-95% non-condensing Manufacturer：GE Industrial Systems, General Electric Company US Model Type：Printed Circuit Board Redundancy Type：Simplex, Dual, TMR Series：Mark VI Product Description The IS230TNCIH4C board is marketed by General Electric as a printed circuit board. This circuit board can be mounted in either a thirteen or twenty-one VME slot-type rack. It will typically be used with a control module when used in a simplex architecture type system but if the chosen architecture is triple redundant it will be used with an IONet, main processor card, and the control module. There are two main communication types that the TNCI model can be used with, these are the Unit Data Highway, which is an Ethernet-based LAN type of communication, and an IONet communication. Please note that the UDH communication driver will typically be associated with the main processor card located within the Mark VI System. While the IS230TNCIH4C board is made up of over a dozen capacitors, resistors, and even more small components, the main visual components of this model are the two terminal blocks, three sub-D pin connectors, two female plug-type connectors, and the metal oxide varistors for which there are twenty-five. The two terminal blocks are labeled TB1 and TB2 and are located near the bottom edge of the board, the metal oxide varistors are located just above the two terminal blocks. The three sub-D pin connectors, which are located near the top edge of the board, are each made up of thirty-seven pins.

Gas turbine is an advanced and complex complete set of power machinery equipment, which is a typical high-tech intensive product. As a carrier of high technology, gas turbine represents the comprehensive level of development of multiple theoretical disciplines and multiple engineering fields, and is the leading technology in the 21st century. The development of gas turbine industry integrating new technologies, new materials and new processes is one of the important symbols of the country's high technological level and scientific and technological strength, and has a very prominent strategic position. Gas Turbine is an internal combustion power machine that uses continuous flow of gas as working medium to drive the impeller to rotate at high speed and convert the energy of fuel into useful work. It is a rotary impeller type heat engine. In the main process of air and gas, only the three components of the Compressor, Combustor and gas Turbine are composed of the gas turbine cycle, known as the simple cycle. Most gas turbines use a simple cycle scheme.

The compressor draws air from the outside atmospheric environment, and compresses it step by step through the axial flow compressor to pressurize it, and the air temperature also increases accordingly. The compressed air is sent to the combustion chamber and mixed with the injected fuel to generate high temperature and high pressure gas; Then it goes into the turbine to expand and do work, and drives the turbine to drive the compressor and the external load rotor to rotate at high speed, realizing the partial conversion of chemical energy of the gas or liquid fuel into mechanical work and output electrical work. Exhaust gas from the turbine is discharged into the atmosphere for natural heat release. In this way, the gas turbine converts the chemical energy of the fuel into heat energy, and some of the heat energy into mechanical energy. Usually in a gas turbine, the compressor is driven by the expansion of the gas turbine to do work, which is the load of the turbine. In a simple cycle, about 1/2 to 2/3 of the mechanical work emitted by the turbine is used to drive the compressor, and about 1/3 of the mechanical function is used to drive the generator. When the gas turbine starts, the first need for external power, generally the starter drives the compressor, until the mechanical work emitted by the gas turbine is greater than the mechanical work consumed by the compressor, the external starter trip, the gas turbine can work independently.

The communication module of the programmable controller is equivalent to the network interface in the local area network. Through the communication module data bus and the host computer of the programmable controller, the hardware and software are used to realize the communication protocol. The communication module of the programmable controller is generally equipped with several interfaces, which can be selected through the selection switch on the communication module to achieve communication with other programmable controller, intelligent control equipment or computer. The input module is used to receive and collect the input signal. The input signal has two types: one is the switch input signal provided by the button switch, the travel switch, the digital dip switch, the proximity switch, the photoelectric switch, the pressure relay, etc. The other is from potentiometer, thermoelectric, speed motor, all kinds of transmitters sent by the continuous change of analog input signal. The input module also needs to convert these different level signals into digital signals that the CPU can receive and process. The function of the output module is to receive the digital signal processed by the central processing unit, and convert it into the signal that can be received by the field implementation parts, used to control the contactor, solenoid valve, regulating valve, speed regulating device, etc., another type of load control is the indicator light, digital display and alarm device.
