Product Description

The IS200EROCH1A model is part of the EX2100 series produced by General Electric Industrial Systems. The EROC acronym in the part stands for Exciter Regulator Options Card. The board will typically support regulator options, third-party GE ground detector, and terminal board power connection. 

The IS200ERGTH1A model connects to the IS200EROCH1A module and will be used to detect resistance leakages to ground any point within the generator's field current. On the front faceplate of the IS200EROCH1A model, there is a keypad connector that can be used to connect an RS-232 cable. Another keypad connector is located on the backplane of this model. 

The IS200EROCH1A has the capability to transmit data from two locations on the regulator rack. On the faceplate of the model, there is a power LED located at the top of the board near the plate which has GE Energy on it. Underneath the power LED there are two ISBUS connectors along with a tool d-pin connector. The model has several circuits integrated into it.

Frequently Asked Questions about IS200EROCH1A

What is the description of the IS200EROCH1A board?

The EROC board is a single-slot, 6U high card. This model is mounted in the left most slot of the simplex control module rack. 

How is the IS200EROCH1A model used in simplex control racks?

When the EROC model is being used in a simplex control rack it will provide ground detector oscillator output and sensing voltages as described for the EGDM board. 

Are the EROC and EGDM boards interchangeable?

Yes. As long as the EROC board is being used in a simplex control rack it acts the same as an EGDM board and interfaces to the EXAM board which is also used to detect ground field voltages. 

Does more than one EROC model need to be used while operating in simplex mode?

No. When the IS200EROCH1A board is operating in a simplex control rack only one of the boards is required.
