About the IS200EXAMG1B

This IS200EXAMG1B EX2100 Series printed circuit board product offering, as detailed above, was originally designed and produced specifically with the with the intended functional role of an Exciter Attenuator Module in mind. This is something of a surprising official functional product description, given the fact that this IS200EXAMG1B device's IS200EXAMG1B functional product number seems to point as its nature as an EX2100 Series product with a normal style of printed circuit board assembly. The EX2100 series that this IS200EXAMG1B printed circuit board or PCB for short belongs to has specific applications in automated drive assembly excitation processes. This IS200EXAMG1B device, while definable as an Exciter Attenuation Module in its own right, is not the originally-developed product of this specific EX2100 Series functionality; that would be the IS200EXAMG1 parent Exciter Attenuation Module notable not making use of this IS200EXAMG1B device's sole B-rated functional product revision.

Hardware Tips and Specifications

Exciter Attenuator module IS200EXAMG1B is used extensively in the EX2100 series. This board is mounted within the auxiliary cabinet and will typically be used to render low-frequency signals that are emitted from the exciter field ground detector module, the signals will then be sent to the sense resistor of the EXAM module. This process will provide current voltages across the resistors which are then dispatched back to the field ground detector. Several other relevant EX2100 Series printed circuit board product offerings are used in conjunction with the IS200EXAMG1B device to achieve certain processes, as evidenced through information contained in the IS200EXAMG1B Instructional Manual attached in our convenient manuals tab above. For example, This IS200EXAMG1B module is designated as working in conjunction with the EGDM separate EX2100 Excitation Control System Series product; specifically for normative detection of field ground current leakage.

There are two distinct differences between the IS200EXAMG1A and IS200EXAMG1B systems. Alterrex applications will need to use two IS200EXAMG1B models along with two EROC-enabled simplex ground detectors. The redundant systems used with this model will result in a test signal originating from the M2 or M1 controllers, these are used with the C controller which controls the switch that is used to flip between the two M controls. There are several manuals that can be used with the IS200EXAMG1B module, these manuals are GEI-100467 and the GEH-6632, the GEI-100467 is a product-specific manual, and the GEH-6632 manual has information on other modules that the EXAM is used with as well as different diagrams which shows the module in the auxiliary cabinet. Given the fact that this IS200EXAMG1B EXAM-abbreviated EX2100 Series product is a member of a now-discontinued legacy product series, General Electric has removed many of this IS200EXAMG1B device's online instructional manual materials. With this being the case, the IS200EXAMG1B functional product number can be turned to as a decent alternative source of IS200EXAMG1B Board hardware component and component specification information; coding for these details in a selection of GE-designated functional naming chunks. For instance, the IS200EXAMG1B functional product number begins through the dual-functional IS200 series tag delegating this IS200EXAMG1B device's normal EX2100 series assembly as well as its domestic original manufacture location. Some of the other relevant hardware details revealed through this number include the IS200EXAMG1B Exciter Attenuator Module's:

  • EXAM functional product abbreviation
  • Normal style of PCB coating
  • Group one EX2100 Series product grouping
  • B-rated primary functional product revision

Frequently Asked Questions about IS200EXAMG1B

What boards do the IS200EXAMG1B models work in conjunction with?

The main board that the IS200EXAMG1B works with is the EGDM which helps detect ground voltages, but the IS200EXAMG1B board also works with the EROC board. 

The EXAM boards can be used in Alterrex applications. How are the boards used in Alterrex applications?

When being used in Alterrex applications two EXAM boards must be used. One of the board is used for generator field circuits, and the other is used for exciter field circuits. 

What is the wiring board type for the IS200EXAMG1B model?

The wiring board type for the IS200EXAMG1B model as stated in the GEH-6632G EX2100 Excitation Control User's Guide is a Bridge and Protection Board/Module. 

Are there differences when the IS200EXAMG1B board detects more than one ground in the field?

Yes! If the IS200EXAMG1B model detects the existence of one ground damage to the rotor is likely not to occur, but if two or more grounds in the field are detected the winding path causes thermal and magnetic imbalances which will damage the rotor and other metallic parts.  

Reviews For IS200EXAMG1B

Internal Review
(5.0)

The IS200EXAMG1B has a low rate of failure in EX2100 and EX2100e Excitation Control Systems and is easily repairable when needed. Because Alterrex applications may use two of these in the system it is important to keep multiple spares on hand in case of defect or failure. This IS200EXAMG1B device's description as an Exciter Attenuator Module is quite interesting given its non-modular, regular style of EX2100 Series assembly. This IS200EXAMG1B product offering is also considered available here for both repair and replacement today. - AX Control Lead Technician
