IS200EACFG1A Exciter AC feedback board

Part Number IS200EACFG1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockIS200EACFG1A is an Exciter AC Feedback Board for the EX2100 excitation system. In the EX2100 Excitation Control, the Exciter Ac Feedback board (EACF) measures the exciter PPT AC supply voltage and current. The terminal board comprises three-phase voltage measuring transformers as well as terminals for two Flux/Air core coils. The voltage and current circuits' outputs are fanned out to three DB9 connections for cabling to M1, M2, and C controllers. The connection connecting EACF to the EBKP backplane board might be as long as 90 meters. 

The exciter auxiliary cabinet houses the EACF board. The board is available in three versions: EACFG1 for 480 Vrms inputs, EACFG2 for 1000 Vrms inputs, and EACFG3 for 1300 Vrms inputs. For the flux/air core input signals, high-frequency noise reduction is provided near the signal entrance point. Where applicable, cable shield terminal screws connected to the chassis ground are situated within three inches of the input screws. Exciter Voltage Measurement The G1 model accepts a single three-phase input voltage in the nominal range of 480 Vrms + 20% at 50/60 Hz. 

The G2 model accepts a single three-phase input voltage in the nominal range of 1000 Vrms + 20% at 50/60 Hz. At 50/60 Hz, the G3 version allows a single three-phase input voltage in the nominal range up to 1300 Vrms + 20%. (1400 V for revision BAA and later). The secondary outputs of the potential transformers on both boards provide a nominal 1.6 Vrms. Inputs for Air Core CT/Flux Coil At 50/60 Hz, the air core current transformers give a nominal secondary output voltage of 0 to 0.8 Vrms. Application Data The three-phase voltage transformers are T1 through T4. Individual screw connectors TB1, TB2, and TB3 are for the voltage inputs. Terminal block TB4 is for wiring from the two Flux/Air core coils. 

The three 9-pin sub-D connectors, J504, J509, and J514 are for cables to the EBKP backplane for the EMIO boards. IS200EACFG1A Replacement procedure Open the auxiliary cabinet door and check any electrical circuits for power before touching them. Disconnect all cables from the EACF board with care. Remove the three screws that secure the EACF board to the mounting and the board itself. Install the new board onto the standoffs with the three screws removed in step 3 in the same location as the old one. Reconnect all connections and wires to the board as labeled, and double-check that cables are positioned properly on both ends. Close the door to the auxiliary cabinet.BOARD - EX2100 AC FE
