Detailed content
-
-
Physical form: Long, narrow PCB; 60-screw terminal strip (2 rows of 30; pins 53–60 internally grounded)
-
Onboard components: 16 inductor coils, 32 metal oxide varistors (MOVs), 3 male vertical pin connectors (JUUS, JUUR, JUUT), 4 jumper switches, 8 box resistors, diodes, capacitors, and 2 transformers (marked U1 and U2)
-
Mounting: Factory-drilled in all 4 corners for rack/panel mounting
-
-
Functional Features: Provides centralized field wiring termination; MOVs and inductors provide surge suppression and signal conditioning; jumpers allow hardware configuration.
-
Application Scenarios: Steam turbine and gas turbine control cabinets; interfaces box-type or barrier terminal blocks to the Mark VI Central Control Module.
-
Installation Requirements: Secure using the 4 corner mounting holes; follow GE manual GEH-series wiring diagrams for terminal strip assignments; verify pins 53–60 are left unconnected as specified on the board silkscreen.
-
Usage Notes: Confirm the exact terminal assignment and jumper settings against the official GE Speedtronic Mark VI documentation before energizing; confirm the spare/unused pins (53-60) are correctly treated as internally grounded.
