Product Description

Exciter Attenuator Module IS200EXAMG1ABB is marketed as a bridge protection board. It has the ability to drive the electrical center for field windings with a low-frequency alternating current relative to the ground. Please note that the main mounting location for this model is in a control module. The control module can be used in two main redundant applications such as triple or simplex redundant. 

With the Unit Data Highway Ethernet-based LAN communication the EXAM board can be used with not only the Mark VI Series for which this model was designed but it can also be used with Human Machine Interface, Historian Software, GE Fanuc PLC-based controls, and many more. The EXAM board will be used with the main control module of the Mark VI system and can also be used with IONets and power supplies. 

When the IS200EXAMG1ABB model is in a vertical orientation you will see a sub-D connector in the lower left corner. This specific connector has nine pins and is labeled as a ground detector. There are also three jumpers on this board, two of which are located toward the middle of the board with the third being located close to the ground detector. The three jumpers are labeled JP1, JP2, and JP3. The JP1 and JP2 jumpers are the same, they operate at the same VRMS which is seven-hundred fifty. The VRMs for the JP3 jumper are three-hundred and seventy-five. 

Two other important components of the IS200EXAMG1ABB board are the stab-on connectors. These stab-on connectors are located near the top of the board and are labeled Vbus-p (E1) and Vbus-n (E2).
