- Utility-scale power generation with GE Mark VI / Mark VIe platforms
System Compatibility
The IS200EPDMG1B is engineered for integration within the following GE control system environments:
- GE Mark VI Turbine Control System — Primary platform; full native compatibility.
- GE Mark VIe — Compatible in hybrid configurations; verify I/O mapping with system documentation.
- GE EX2100 / EX2100e Exciter Systems — Commonly paired; confirm wiring harness and backplane connector compatibility.
- GE Speedtronic Series — Legacy integration possible with appropriate interface modules.
Not compatible with Siemens, ABB, or Emerson DCS platforms without custom engineering adapters.
Selection Guide
Use the following criteria to determine whether the IS200EPDMG1B is the right module for your application:
- Step 1 — Confirm Platform: Verify your turbine control system is GE Mark VI or Mark VIe. Check the system nameplate or OEM documentation.
- Step 2 — Identify Slot/Rack Position: Locate the EPDM slot in your I/O rack. Cross-reference with the Mark VI system wiring diagram.
- Step 3 — Check Revision Compatibility: Compare the revision letter (G1A, G1B, G1C) against your system’s approved hardware list (AHL) or BOM.
- Step 4 — Evaluate Condition Requirements: For critical applications, specify new OEM stock. For budget-sensitive MRO, certified-refurbished units from Konmask.com offer a cost-effective alternative.
- Step 5 — Confirm Lead Time: Contact Konmask.com for real-time stock availability and lead time before raising a purchase order.

Replacement & Compatibility FAQ
Q: Can IS200EPDMG1A replace IS200EPDMG1B?
A: In most Mark VI configurations, yes — revision A and B are functionally equivalent. However, always verify against your system’s Approved Hardware List (AHL) and consult GE documentation or your system integrator before substitution.
Q: Is IS200EPDMG1B compatible with Mark VIe?
A: Partial compatibility exists in hybrid Mark VI/VIe architectures. Confirm I/O rack slot assignments and backplane connector pinouts with your OEM documentation.
Q: What is the difference between EPDM and EPSM modules?
A: EPDM (Exciter Power Distribution Module) manages power routing to exciter subsystems. EPSM (Exciter Power Supply Module) provides regulated DC power. They serve complementary but distinct functions and are not interchangeable.
Q: Do you offer tested/refurbished units?
A: Yes. Konmask.com stocks both new OEM and certified-refurbished IS200EPDMG1B units. All refurbished modules are functionally tested and include a warranty. Test reports available on request.
Q: What is the lead time for IS200EPDMG1B?
A: Lead time varies by stock availability. Contact us at support@konmask.com or +0086 19859288691 for real-time availability and shipping estimates.
Q: Can you provide a Certificate of Conformance?
A: Yes. CoC, test reports, and traceability documentation are available upon request for all units shipped from Konmask.com.
