The IS200EPCTG1A model is part of the EX2100 series. This model is specifically designed to receive and condition generator current transformer and potential transformer feedback. The input voltages that are used in regard to the PT voltage are two three-phase generators. For the CT current inputs, the current levels of 1 A-5 A come from two generators. When it comes to the type of board the IS200EPCTG1A is, it is an input/output terminal board.
The analog input of the IS200EPCTG1A model will be anywhere from 0-10 V or 4-20 mA. When connecting the CT and the EPCT the wire gage that is connected can be up to #10 AWG, and the cable length can be up to 1000 feet. Any of the currents and generator voltage from the CTs and PTs are wired through to the EPCT board. When the currents and voltages are wired through to the EPCT, the IS200EPCTG1A board will act as a signal conditioner that will scale and isolate the signals that have been sent through the CTs and PTs.
This model has very low market availability at this time but can still be found, especially here at AX Control where we try to keep several on the shelves.
