GE Mark VI Servo Interface Characteristics
The IS200TSVCH2A provides a physical field interface between the Mark VI control system and connected actuators or external sensors. Its two coil outputs support servo-related actuator connections, while two pulse-rate inputs accept field pulse signals.
The board uses two removable barrier-type terminal blocks positioned along one long edge. This arrangement provides direct field wiring access and allows the terminal blocks to be removed during servicing.
The PCB also contains four transformers, three D-shell connectors, multiple vertical plug connectors, and adjustable jumper switches. Reference designators identify board components on both sides of the PCB.
The board supports applications involving heavy-duty, aviation gas, and steam equipment. The supplied data specifies compatibility with the PSVOH1B battery pack.

Field Installation Guidelines
- Verify the complete IS200TSVCH2A part number before installation and match it with the Mark VI system documentation.
- Mount the board according to the original cabinet or panel arrangement.
- Route field wiring separately from high-voltage power conductors where the installation design permits.
- Maintain clear identification of the two coil-output circuits and two pulse-rate input circuits.
- Check terminal-block seating before energizing the associated control circuit.
- Inspect D-shell connectors and vertical plug connectors for correct engagement and mechanical damage.
- Set jumper switches only according to the applicable GE Mark VI application documentation.
- Use appropriate shield termination and grounding practices for connected field signal wiring.
- Confirm the PSVOH1B battery-pack interface before connecting associated circuitry.
- Perform continuity and wiring checks before applying system power.
