GE IS200TSVCH1AJE – Terminal Board for Mark VI turbine servo/valve I/O
The GE IS200TSVCH1AJE is a Mark VI-series terminal board designed to bring field wiring for turbine hydraulic controls back to the controller cleanly and reliably. From my experience, TS-series boards like this are typically used where you need stable connections for servo or solenoid valve control and associated feedback (often LVDT/RVDT or discrete permissives). It’s a straightforward way to keep your turbine cabinet tidy while preserving signal integrity and serviceability.
One thing I appreciate is how these boards simplify maintenance—techs can land and verify field conductors on labeled terminals, while the controller-side cabling remains unchanged. You might notice that, in many cases, this cuts troubleshooting time when you’re balancing a valve loop or chasing a nuisance trip contact.

Key Features
- Purpose-built Mark VI termination – Provides organized landing points for turbine valve control signals and related feedback, reducing wiring errors.
- Robust field connectors – Screw/clamp terminals (typical for this family) support secure connections and quick re-termination during outages.
- Clean segregation of I/O – Helps separate power-side valve circuits from low-level feedback lines for lower noise pickup in many cabinets.
- Service-friendly layout – Clear terminal labeling and controller-side ribbon/plug interfaces make signal tracing faster when time is tight.
- Designed for turbine environments – Matches GE Mark VI control practices and cabinet mounting conventions, which typically simplifies retrofit work.
Technical Specifications
| Brand / Model | GE (General Electric) / IS200TSVCH1AJE |
| HS Code | 8538.90 (Parts for industrial control equipment) |
| Power Requirements | No separate onboard supply; receives power via the Mark VI I/O interface and field wiring as configured |
| Dimensions & Weight | Board-level terminal board; standard GE IS200 TS-series form factor; lightweight (< 1 kg typical) |
| Operating Temperature | 0 to 60°C typical for panel-mounted Mark VI I/O (cabinet conditioned) |
| Signal Input/Output Types | Field termination for turbine valve control circuits (servo/solenoid) and related feedback or permissives; exact I/O depends on site wiring option |
| Communication Interfaces | Controller-side ribbon/plug interface to Mark VI I/O; no Ethernet/serial on the terminal board itself |
| Installation Method | Panel/cabinet mounting via standoffs; field wiring on labeled terminal blocks; controller interconnect via harness |
Related or Supporting Products
- IS200TSVCH1A – Same family without the JE-specific build revision; typically interchangeable subject to wiring and revision rules.
- IS200TREGH1B – Trip relay terminal board used in many Mark VI turbine trip circuits; pairs well in cabinets where both trip and valve control terminations are needed.
- IS200TRLYH1B – Relay output terminal board for discrete control; often used alongside valve control terminations.
- IS200TBCIH1C – Analog input terminal board for process/conditioning signals; useful when adding more feedback points to the same cabinet.
Quick user note: a maintenance lead at a combined-cycle site told me swapping in a like-for-like TS-series board cut their loop checkout by half a shift, mainly because the terminal labeling matched their legacy drawings closely. That seems to be common when staying within the IS200/Mark VI ecosystem.
Installation & Maintenance
- Environment: Install in a Mark VI cabinet or equivalent enclosure meeting industrial control panel standards; maintain ventilation and keep within 0–60°C ambient.
- Wiring: Use properly ferruled conductors; separate high-current valve wiring from low-level feedback to minimize noise. Torque terminals per GE guidance.
- Grounding: Bond the board ground reference to the cabinet ground scheme; keep shield drains terminated at one end as per site EMC rules.
- Safety: De-energize actuator power (and hydraulics if applicable) before servicing. Lock-out/tag-out is strongly recommended.
- Routine maintenance: Inspect terminals for looseness each outage, check for discoloration or contamination, and clean with electronics-safe methods. Verify valve loop polarity and feedback scaling after any re-termination. Firmware updates apply to the controller/I/O pack, not the passive terminal board.
Quality & Certifications
- Factory build practices in line with GE Mark VI quality standards; units are typically CE compliant for industrial environments.
- UL Recognized Component status is common for this product family.
- RoHS status may vary by production date and market; confirm per serial/revision if required for your site.
- Manufacturer warranty policies vary by channel; our supplied units carry a 365-day warranty as stated above.
