Product Description
The IS200EGPAG1BEC printed circuit board was originally manufactured by General Electric shell company GE Industrial Systems; a company responsible for the manufacture of all of the EX2100 Excitation Control Systems Series products. This PCB can be more explicitly defined as an Exciter Gate Pulse Amplifier, and is modified through its inclusion of three significant product revisions.
Hardware Tips and Specifications
Before examining the various hardware components important to this devices's functionality as a Gate Pulse Amplifier, it is important to consider the actual functionality of the product itself. This EGPA board was created as a sort of interface that acts between the EX2100 Series drive assembly's control and its Power Bridge. This IS200EGPAG1BEC board collects the compatible ESEL board's various gating commands in order to generate gate firing pulses attributed to six total Silicon Controlled Rectifiers or SCRs. The IS200EGPAG1BE Exciter Gate Pulse Amplifier features additional functionality in its interfacing for bridge airflow monitoring, temperature monitoring, and current conduction feedback. While many EX2100 Excitation Control System Series Exciters utilize a series of Klixon switches for their temperature control and alarm generation, newer EX2100 exciter models may incorporate a RTD instead. Two total switches are wired to the EGPA board, and may require retrofitting to their existing bridges. Both of these switches are classified as thermal switches, and one opens up at the alarm level temperature rating of 170 degrees fahrenheit, while the other opens at the trip level of 190 degrees fahrenheit. When either of these two mentioned switches are opened, a bridge over temperature alarm is generated that may interrupt normative EX2100 drive assembly activity. In the case that both switches in the EGPA board assembly were to be activated, a fault and fault trip are generated for the IS200EGPAG1BEC PCB.
A number of additional hardware specifications for this IS200EGPAG1BEC printed circuit board are available upon a breakdown of its individualized IS200EGPAG1BEC product number, which immediately yields the IS200 Series Tag. This tag is included with dual naming responsibilities for this EGPA-abbreviated PCB; detailing the product as a domestically manufactured PCB with no special assembly type. An instance of the EGPA functional acronym in the IS200EGPAG1BEC product number is shrugged for the G1 series grouping tag; which has dual naming functionality for the IS200EGPAG1BEC board similarly to the IS200 series tag. This G1 tag reveals the EGPA board to be a normally-coated PCB with a group one EX2100 Series grouping. The final trailing "BEC" digits in this product's part number reveal its three-fold significant revision history.
