GE IS200EDCFG1A Exciter DC Feedback Board is to measure the excitation voltage and excitation current of the SCR bridge. The excitation voltage feedback of the IS200EDCFG1A will always be measured at the negative terminal of the bridge device and the positive terminal of the shunt. When the voltage is scaled with the jumper resistor, the signal will continue to be input to different amplifiers. Both pins on the J-16 connector are used for external VDC voltage. Pin one is the positive 24 VDC input of the DC-DC converter. Pin two is also 24 VDC, but it is the common input of the DC-DC converter. The fiber optic connectors in the system are marked as CF OF and VF OF. The CF OF connector is the field current feedback pulse, HFBR-1528 fiber optic driver/connector.

Frequently asked questions about the product are as follows:

-What is the GE IS200EDCFG1A?

S Monitors and feeds back DC signals from the excitation system, which can be used in turbine control.

What is the main function of the module?

Monitors the DC feedback signal from the exciter and provides this data to the control system for proper regulation of the excitation system.

-Where is it typically used?

It is used in gas and steam turbine control systems, power generation applications.
