GE Mark V Series DS200CDBAG1 Contactor Driver Boards

About the DS200CDBAG1

As previously mentioned, this DS200CDBAG1 printed circuit board product, or PCB for short, is a contactor driver board manufactured by General Electric for placement in its Mark V turbine control system series of automatic drive assemblies. This DS200CDBAG1 PCB is no longer actively produced by the larger Mark V series, and its eventual discontinuation was necessary given the industry-wide obsolescence of many of its products. With that in mind, the Mark V series to which this DS200CDBAG1 printed circuit board, or PCB for short, belongs remains the final instalment of General Electric's Mark product line, incorporating its patented Speedtronic control system technology into its various products. This DS200CDBAG1 PCB is defined in the original instruction manual material via the official functional product description of the contactor driver board, and it does exist as a revised version of the original base for this intended Mark V series functional role, as indicated by its DS200CDBAG1 functional product number without any trailing, alphanumeric digits denoting a revision.

Hardware Tips and Specifications

The GE Contactor Driver Board DS200CDBAG1 opens and closes the contactors in its larger Mark V Series Autodrive assembly. Before touching the board for installation, be sure to disconnect power to the drive and test the board to ensure that there is no power in the board. Also, do not remove the board while the drive is powered. Static electricity can damage the board. Use a grounding strap to work on the board and store the board in a static protection bag. the DS200CDBAG1 has a jumper. jp1 is a 3-pin jumper for factory test purposes only. Keep pins 1 and 2 covered for normal operation. When pins 2 and 3 are covered, it is for factory use only. The DS200CDBAG1 also has a potentiometer to control the amount of current applied to the contactor coil. This is set at the factory and it is best practice not to change it. Voltage limiting in the assembly of this DS200CDBAG1 Mark V Turbine Control System series product is handled in the same manner as most General Electric Speedtronic products; accepting a variety of voltage-limiting hardware components including capacitors, rectifiers, diodes, and integrated circuits through its internal assembly. In addition to this, the base board and components of this DS200CDBAG1 product receive the normal level of protection from daily wear and tear and insulation due to its normal style of PCB protective coating, which wraps and protects the individual DS200CDBAG1 board hardware components according to their functional priority.

The DS200CDBAG1 also features test points that can be used to test board operation. One test point is a common reference point for the board. One test point is a 15 VDC test point referenced to the common reference point. One test point is for contactor driver reference voltage. connector 1TB on the DS200CDBAG1 board consists of four sections (1TBA, 1TBB, 1TBC, and 1TBD). Carefully note the location of the connector on the board and use a screwdriver to pry the sections apart. The connectors on the replacement board may be in different locations, so care must be taken to plug the sections into the correct connectors. There is also a fuse available for this DS200CDBAG1 Mark V series assembly; this fuse is designated in the original instruction manual material as a 4 amp, 125 V, 2AG slow blow fuse and can be replaced if it continues to blow (this is usually applicable to any DS200CDBAG1 board assembly).

Frequently asked questions about the DS200CDBAG1

Why does the DS200CDBAG1 provide power?

The DS200CDBAG1 provides power for switching on and off contactors controlled by the DS200DCFB power board, the DS200SDCI DC power supply and the instrument panel or the feedback acquisition and power board. However, the DS200CDBAG1 can only operate one high-speed contactor at a time.The DS200CDBAG1 is powered by 75-140 volts AC/DC and the input power to the DS200CDBAG1 is fused by FU1.

Does the DS200CDBAG1 have a potentiometer?

Yes, the DS200CDBAG1 includes an adjustable potentiometer for setting the contactor drive current.The DS200CDBAG1 has an RV1 potentiometer for controlling the amount of current that drives the contactor coils, measured using test points REFA and ACOMA.

What can I find in the manual for the DS200CDBAG1?

The manual for the DS200CDBAG1 is the Contactor Drive Board Manual. This manual is a GE Industrial Control Systems manual, manual number GEI-100182B In this DS200CDBAG1 manual, you will find safety symbols for the DS200CDBAG1. descriptions of the DS200CDBAG1 functions, and application data for the DS200CDBAG1.

How does the DS200CDBAG1 close the contactor?

The DS200CDBAG1 closes the contactor by applying 105 VDC for 250 milliseconds to force the contactor to close, and then the DS200CDBAG1 regulates the contactor drive current at the level set by potentiometer RV1 to keep the contactor closed.
