GE Mark VI Servo Signal Interface
The IS200TSVOH1BBB functions as a termination board for the servo-related hardware interface in a GE Mark VI SPEEDTRONIC system. Therefore, installation should preserve the intended signal routing between the terminal board and associated control circuitry.
The board specifies a +/-15 VDC supply and less than 3 W typical consumption. In addition, the 500 VDC isolation specification defines the stated electrical separation capability. The 250 Hz bandwidth provides the specified signal-frequency operating range.
Because GE lists the assembly as discontinued, technicians should verify the exact board revision and system compatibility before installation. Furthermore, replacement work should maintain the original terminal assignments and field wiring configuration.

Field Installation Guidelines
- Verify the complete board identification, including the IS200TSVOH1BBB suffix, before installation.
- Remove system power before disconnecting or reconnecting field wiring.
- Confirm terminal assignments against the applicable GE Mark VI system documentation.
- Keep signal wiring separated from high-voltage and high-current conductors where the cabinet design permits.
- Maintain cable shielding and grounding practices specified by the control-system installation documentation.
- Inspect terminal connections for loose conductors, damaged insulation, contamination, or mechanical stress.
- Verify the +/-15 VDC supply before applying power to the installed board.
- After installation, check field signal continuity and verify that connected circuitry operates within the specified 250 Hz bandwidth.
- Do not substitute a different board revision without confirming system compatibility.
- Record the installed board model and revision for future maintenance documentation.
