Product Description

Exciter Regulator Options Card IS200EROCH2A is the second version of the IS200EROCH models. The primary function of this board is to be used in conjunction with the IS200ERGTH1A, or any of the GE ground detector boards to detect leakage resistance to the ground at any point when being used with the generator field current. This board has the ability to provide transfer of data to two locations that are on the regulator rack and can communicate using the keypad connector on the faceplate or in the backplane of the model. 

The IS200EROCH2A board has a number of integrated circuits within the main portion of the board. When you are looking at the front of the board towards the bottom of the faceplate there are two d-pin connectors which are labeled as redundant and ground detector. This model is used within the Innovation Series of EX2100 Excitation Control models. 

While the IS200EROCH2A is no longer produced by General Electric and is mostly obsolete this model can still be found on the shelves here at AX Control INC. If you have any questions regarding the operation or repair of this model please feel free to contact us by phone number or email. 

Frequently Asked Questions about IS200EROCH2A

Can the IS200EROCH2A model be used in redundant modes?

Absolutely not. The only mode that the EROC model can be used in is simplex. For redundant mode applications the EGDM board, which functions similarly to the EROC board is required. 

The IS200EROCH2A model is mounted on the ESBP backplane. In which section will the IS200EROCH2A model mount?

The IS200EROCH2A model mounts in controller M1. 

The EROC board is similar to the EGDM board. How does the EROC interact with the EXAM board?

When the EROC board is being used rather than the EGDM board, the EROC will interface with the EXAM board. It also sends information regarding ground detector functions to the DSPX model. 

Is there a part-specific manual for the EROC models?

Yes. The part-specific manual used for the EROC board is the GEI-100526 manual, but as this manual is difficult to find the best manual to use is the GEH-6632 EX2100 Excitation User's Guide.
