About the IS200VPROH1BCB

Hardware Tips and Specifications

The IS200VPROH1BCB is a board component from GE that is designed to fit into the Speedtronic Mark VI system. The IS200VPROH1BCB has, in its normal style of GE Mark VI Speedtronic series assembly:

•  an extra-wide front faceplate
  • hinged along one edge
  • includes multiple screw points
• clips that help retain the board within the rack system
• LED indicators in several groups.
  • labeled X/Y/Z, 8/4/2/1, CD, TX, RX,  power fault, and power normal
• a power plug
• an ethernet and IONet connector
• several other D-shell connectors

The IS200VPROH1BCB is primarily used as protection for the turbine via emergency overspeed. The board also offers backup synch check protection and three analog current inputs.  There are nine thermocouple inputs that are typically only used for over-temp protection on gas turbine systems.  

IS200VPROH1BCB Protection Board Device Power Supply

Since protection modules are always triple redundant, any single board can be powered down and replaced without putting the protection system in jeopardy. The IS200VPROH1BCB has a VME interface that will allow programming and testing within the VME rack, but this is neutralized once plugged into the protection module. 

The IS200VPROH1BCB includes its own power supply located on-board, which generates 5VDC and 28VDC from the 125VDC from the PDM. Refer to General Electric data sheets, user guides, or manuals for more detailed information. These publications should have been provided with your OEM purchase.  AX Control maintains a library of documents should you need a replacement of any of these necessary items.
