DS200FHVAG1ABA | GE High Voltage Gate Interface Board

Description

The High Voltage Gate Interface Board DS200FHVAG1A is a board that provides SCR gate interfaces and cell voltage monitoring functions for the power converter. There is a diagnostic LED for the SCR Status Circuit that allows for a visual indication of the potential of blocking voltages. The primary use of the High Voltage Gate Interface Board DS200FHVAG1A is to supply cell voltage and SCR gate interference monitoring, these functions occur through the LCI power converter. For each SCR there is one of these boards. This board comes equipped with an SCR Status Circuit LED which will give off a visible indication that there is a blocking presence at the voltage, please note that this lED should be visible whenever the bridge power is activated and will dim when the SCR conduction angle has increased. The DS200FHVAG1A model has a gate pulse transformer, this specific transformer is a toroidal transformer that is soldered to the board. There is also a fiber-optic transmitter on this board, it is critical to note that if a fiber-optic is not connected to the device then a rubber plug must be inserted into the U1 to prevent debris from accumulating on the lens. Please note that even after an hour of exposure to the lens in particularly dusty environments noticeable pollution can be seen on the lens.

The communication module of the programmable controller is equivalent to the network interface in the local area network. The communication module data bus is connected with the host of the programmable controller, and the communication protocol is realized by hardware and software together. 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 realize the communication with other programmable controllers, intelligent control devices or computers. 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 stroke switch, the digital dip switch, the proximity switch, the photoelectric switch, the pressure relay, etc. The other is a continuously changing analog input signal sent by potentiometer, thermoelectric, tonometer motor, and various transmitters. 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 processor, and convert it into a signal that can be received by the field executive parts, which is 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.

It is an electronic power supply board, mainly used to supply the electric energy required by the excitation system of the power generator.
