DS200CDBAG1BBB | GE Contactor Driver Board

Description

The GE Contactor Driver Board DS200CDBAG1BBB opens and closes a contactor. All power, input signals, and output signals are connected to the board through 1 connector on the board (1TB). The 1TB connector is made up of four sections. Three plug connectors supply the power and signals to the connector. The four sections are 1TBA, 1TBB, 1TBC, and 1TBD. To remove the connector, use a screwdriver to help pry the connectors apart from the board. Before you remove any cables, it is best practice to label all cables to avoid confusion when you install the replacement board. Also, one fuse connector is located on the board. If replacement is necessary use a 4 amp 125V, 2 AG slow-blow fuse. If the fuse blows often, you might suspect that the board needs to be replaced. It might be necessary to troubleshoot the board if you suspect the board is not functioning properly.  Test points are on board for you test various functions of the board. You’ll need to use isolated test equipment to test the board. One point is the common reference point. The second test point is used for the 15 V dc power supply reference. The third is for the contactor driver reference.

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. The excitation system of electric generator is an important part of electric power plant, which is used to control the output voltage and current of electric generator to maintain the stability of electric power system. Features and functions: This exciter source board may have the following characteristics and functions: Power output: It provides the power supply voltage and current required by the excitation system to ensure that the generator can produce a stable power output. Voltage regulation: The exciter source board usually has a voltage regulation function to adjust the output voltage of the power generator as needed. Overcurrent protection: To protect the excitation system from current overload, the power supply board may include overcurrent protection. Communication interface: Some exciter source boards may have a communication interface for communication and data transfer with the generator control system or monitoring system. High reliability: Considering the criticality of electric power plants, this type of power supply board usually has high reliability and stability.
