Description
The GE IS200WROBH1AAA is a relay output termination board engineered for the Mark VI Speedtronic turbine control system. It functions as the physical interface between the system’s control core and external industrial equipment, such as solenoid valves, motor starters, and trip circuits. Plant engineers install this board to drive high-power heavy-duty field devices using low-power logic signals originating from the I/O processor. Are you experiencing intermittent relay chattering or failed contact states on an aging turbine deck? This board features 18 form-C relay outputs, providing the mechanical isolation necessary to shield sensitive upstream control electronics from inductive field surges.

Commercial Condition and Global Logistics Availability
We supply the IS200WROBH1AAA in New Surplus (Factory Boxed) or Refurbished (100% Channel Tested) condition. Because a failure in the relay matrix can halt a critical startup sequence, our lab technicians physically actuate every single relay channel under load on a dedicated testing console before releasing the hardware for global dispatch.
- Availability: Maintained in stock for immediate international distribution
- Lead Time: Dispatches within 24 to 48 hours from receipt of payment
- Warranty: 12-month comprehensive warranty covering parts and labor
- Pricing Note: The displayed pricing represents a baseline market index. Actual commercial costs depend on global supply pool variations, core exchanges, and emergency urgency factors. Reach out to our trade desk to request a binding formal quote.
Cross-Border Logistics and Export Compliance Management
Shipping specialized turbine infrastructure components across international borders requires a strict adherence to international trade laws. We coordinate daily prioritized air freight shipments via DHL, FedEx, and UPS to keep global infrastructure running across the Americas, EMEA, and Asia-Pacific regions.
For customs declaration purposes, this board is categorized under HS Code 8537.10.91, which applies to industrial programmable logic controllers and relay control interfaces. The “AAA” trailing suffix indicates specific manufacturing artwork revisions; don’t worry about local customs flagging this variant as long as the base model IS200WROBH1 matches the commercial invoice exactly. Our logistics compliance specialists manage all necessary export document compilation—including Electronic Export Information (EEI) filings for US-origin parts—ensuring your shipment passes through customs clearance checkpoints without administrative holds or unexpected destination delays.
GE Mark VI WROB Field Engineering FAQ
- Can I mix AC and DC voltages across different relay channels on the same board?
Well, technically the internal traces provide sufficient isolation between channels to allow different voltage potentials. In our field experience, however, mixing high-voltage AC and low-voltage DC on adjacent terminal blocks significantly increases the risk of cross-talk and accidental short-circuits during routine loop testing. We highly advise keeping similar voltage classes grouped together.
- What do the configuration jumpers on the board actually control?
These jumpers determine whether the individual relay channels utilize an internal power distribution bus or function as isolated “dry” contacts. Before applying field power, double-check that the jumpers match your plant’s wiring schematics. Leaving a jumper in the wrong position can accidentally back-feed 125 V DC directly into an unrated external device.
