IS200DSVOH2B

About the IS200DSVOH2B

The IS200DSVOH2B is part of the GE General Electric Mark VI Turbine Control Series and functions in the system as a Simplex Din-rail Mounted Servo Terminal Board. There are always additional letters (revisions) reflected after the base part number of IS200DSVOH2B. However, many customers will order this terminal board using the base part number alone as the last two letters do not alter functionality in this specific case. 

When installed in the Mark VI application, the IS200DSVOH2B connects to the VSVO card via two cables, 15-Pin and 37-Pin respectively. The DSVO board features the following components: Input/Output for Qty 6 LVDT Position Sensors, Qty 2 pulse rate Inputs that aid with flow measurement, and Qty 2 Servo Valve Outputs. Additionally, because cabinet space is often limited, the DIN rail design of the IS200DSVOH2B allows for multiple of these modules to be stacked vertically along the rail. 

While the H1B version of this simplex board did not have Class 1 Division 2 Certification, the H2B model does carry these certifications. Information about this board can be found in the GE manual GEH-6421C Mark VI System Guide in Chapter 9. If deeper troubleshooting analysis is needed, please contact an authorized technician with experience diagnosing faults/errors in Mark VI Turbine Control Applications.
