Selection Guide
Use the following criteria to confirm the DS200TCQBG1BBC is the correct module for your application:
- ✅ Your system is a GE Mark VI turbine control panel
- ✅ The failed or required board is located in the RST Overflow slot of a TCQB rack
- ✅ Your panel label or BOM lists part number DS200TCQBG1BBC or a compatible suffix (BBB, A)
- ✅ Your ToolboxST configuration references the TCQB I/O module type
- ⚠️ If your system is Mark VIe, consider the IS200TCQBG1A instead
- ⚠️ If the suffix differs (e.g., G1A vs G1BBC), contact us to verify cross-compatibility
