Compatible Replacement & Equivalent Models
When the IS200TPROH1BCB is unavailable or discontinued, the following models may serve as functional equivalents or drop-in replacements depending on your system revision. Always verify firmware and hardware revision compatibility before substitution.
- IS200TPROH1BAB — Earlier revision, same functional role; verify relay output count
- IS200TPROH1CAB — Later revision with enhanced diagnostics; backward compatible in most Mark VI racks
- IS200TPROH2A — Upgraded variant; confirm rack slot and backplane connector compatibility
- IS200TPROS1B — Simplex protection relay output board; suitable for non-TMR configurations
- DS200TPROH1BDB — Mark V predecessor; not directly interchangeable but functionally analogous

Selection Guide
Use the following criteria to confirm the correct board for your application:
- Step 1 — Identify your Mark VI revision: Check the UCSC controller nameplate for hardware revision (A, B, C).
- Step 2 — Confirm board revision suffix: BCB suffix indicates Revision B board with C-level PCB changes. Match to your existing board label.
- Step 3 — TMR vs. Simplex: IS200TPROH1BCB is used in TMR configurations. For simplex, consider IS200TPROS1B.
- Step 4 — Relay output count: Verify the number of relay output channels required matches your I/O list.
- Step 5 — Firmware version: Confirm ToolboxST firmware version compatibility with your existing Mark VI software release.

Replacement & Compatibility FAQ
Q: Can IS200TPROH1BCB replace IS200TPROH1BAB directly?
A: In most cases yes, as BCB is a later revision. However, always verify with GE ToolboxST that the firmware supports the newer board revision before hot-swapping in a live system.
Q: Is this board compatible with Mark VIe systems?
A: No. Mark VIe uses the IS420 series boards. IS200TPROH1BCB is specific to Mark VI architecture.
Q: Do you provide a warranty?
A: Yes — 12-month warranty on tested/refurbished units, 24-month on new OEM stock. Contact us for warranty terms.
Q: Can you source this board if it’s not in stock?
A: Yes. Konmask.com has an extensive global sourcing network for obsolete and hard-to-find GE Speedtronic parts. Submit an RFQ and we will respond within 24 hours.
Q: What is the difference between IS200TPROH1BCB and IS200TPROH1CAB?
A: The CAB suffix indicates a later PCB revision with minor component updates. Both perform the same protection relay output function; CAB may include enhanced diagnostic LED indicators.
