About the IS200TPROH1BCB
General Electric (GE) developed the IS200TPROH1BCB protective termination board as a component in the Mark VI series made for gas/steam turbine management and automation. The IS200TPROH1BCB is a version of a printed circuit board or PCB. The IS200TPROH1BCB and the other components in the Mark VI series are a part of the much larger Mark family of turbine controls.
The IS200TPROH1BCB PCB is rectangular in shape. The most prominent components on the IS200TPROH1BCB are two (2) terminal blocks and two (2) relays or contactors. The terminal blocks are black and large in size. They are positioned on the left edge of the IS200TPROH1BCB vertically. The relays featured on the IS200TPROH1BCB are paired together vertically in the center of the top of the IS200TPROH1BCB. These relays are mostly red and they have parts on the top that are yellow and black. Right next to these relays on the left side are two (2) red circular MOVs or metal oxide varistors. Several solid yellow capacitors that are small in size are featured throughout the IS200TPROH1BCB mostly on the board’s lower half. The right edge of the IS200TPROH1BCB is lined with three (3) medium sized jack connector ports identified by the names JZ1, JY1, and JX1. Three (3) more of these connector ports which are smaller (about half the size) than the others have been lined up to the left of these other connector ports. The smaller connector ports have been identified by the names JZ5, JY5, and JX5. Three (3) black variable resistors or potentiometers have been situated at the top right of the IS200TPROH1BCB.
