Product description

IS200EGDMH1AFF model is an exciting field grounding detection module, that is, the functional abbreviation of EGDM. During installation, the module will be mounted on the excitation power backplane rack and will be close to the EPSM module. The module works on a single redundant system that requires one EGDM module and a redundant system that requires three EGDM modules. The IS200EGDMH1AFF is used with the EXAM module, and the two modules work together to determine the potential for field ground leakage at any point on the DC or AC side.

When the EGDM module and DSPX module are connected through optical fibers, the EGDM module sends the used voltage to the DSPX module through optical fibers. After this process has occurred, the voltage will be checked and an additional alarm will be added by DSPX. There are three LED indicators on the EGDM module panel. The IS200EGDMH1AFF module has three indicators: power indicator, primary indicator, and optional primary indicator.

One of the best ways to identify the module is through the alphanumeric catalog number printed directly on the board, but there is also a small board at the bottom of the panel that indicates what the module is.

FAQ about IS200EGDMH1AFF

How do I use the EXAM module with the EGDM module?

One way the exam module works is by sensing a voltage through a grounding resistor and then sending the signal to the EGDM through a nine-conductor cable.

How to configure the IS200EGDMH1AFF board if the IS200EGDMH1AFF board is used in a redundant system?

If an EGDM board is used in a redundant system, the three boards will be configured as Controller (C), Master 1 (M1), and Master 2 (M2). The configuration of each EGDM is controlled by a set of program pins on the P2 connector.

Is IS200EGDMH1AFF model an active system?

Yes, we do! As an active system, the EGDM model will apply voltage to the field circuit.

What does the EGDM model do?

The EGDM model has many functions, one of which is to detect the field leakage resistance between any point in the field circuit and the generator.
