Flux/Air Core Coils Connector TB4
Inputs Power Potential Transformer (PPT)
Phase-Voltage Transformers 4

Product Description

The IS200EACFG2A is the second version of the IS200EACFG models. Version G2 has four transformers on the board that support one three-phase input voltage. The transformer blocks are T3, T4, T1, and T2; terminal block T3 is at the top of the board closest to the alphanumeric catalog, T4 and T1 are in the middle of the board, and terminal block T2 is closest to the bottom of the board and nearest to the TB4 coil input terminal. The voltage measuring range on the G2 version of this module is up to 1000 VRMS. 

If your board has malfunctioned and needs to be replaced, the panel where the board is installed must be de-energized before removal. When removing the IS200EACFG2A board test all of the electrical circuits located within the auxiliary cabinet to ensure that the power is off. Disconnect the cables from the EACF board and ensure the connecting cables are labeled properly to ensure a quick and easy reinstallation. 

When connecting the coil cables to terminal TB4 on the IS200EACFG2A model the first and highest coil will connect to terminal 1, and the lowest part of the same coil connects to terminal two. Terminals three and four are for coil two, the highest part of coil two connects to terminal three and the lowest part connects to terminal four. 

Frequently Asked Questions about IS200EACFG2A

The IS200EACFG2A is a G2 version, how does it differ from a G1 version of the EACF boards?

The G2 version of the EACF boards differs from the G1 version through its voltage range, it still supports a single three-phase input voltage but the nominal range should be 1000 VRMS at positive twenty percent at 50/60 Hz. Another way that the G2 version differs from the G1 version is that the G2 version has all transformers while the G1 version only has T3 and T2. 

What is the secondary output voltage of the air core CT/flux coil inputs on the IS200EACFG2A board?

The output voltages from the air core CT/flux coil inputs typically read in the range of 0-0.8 VRMS at 50/60 Hz. 

Does the IS200EACFG2A board need to be connected to another board? What are the connectors that allow for this to occur?

Yes the IS200EACFG2A board does need to be connected to another board. The standard connection is the EBKP backplane for the EMIO boards, to connect the IS200EACFG2A board to the EBKP backplane there are three nine-pin sub-D connectors labeled as J504, J509, and J514 that allow for this connection. 

What are the corresponding terminal boards and their nomenclatures on the IS200EACFG2A model?

There are four terminals within the IS200EACFG2A board. TB1 is a PPT Phase A signal, TB2 is a PPT Phase B signal, TB3 is a PPT Phase C signal, and TB4 has a number of nomenclatures which are Coil1, high with terminal 1, Coil1, low with terminal 2, Coil2, high with terminal 3, and Coil2, low with terminal 4. 

Reviews For IS200EACFG2A

Internal Review

The IS200EACFG2A model supports up to 1000 VRMS. The more VRMS the model supports indicates it can be installed where the exciter PPT current will be higher. - AX Control Tech Team
