🔌 Interface Function
The IS200STCIH2A serves as the connection point between field thermocouple wiring and the Mark VIe control system. It provides organized terminal connections for temperature sensors while allowing the connected I/O pack to perform signal processing and system communication.
Correct thermocouple type, polarity, wiring method, and channel assignment must be verified before operation to prevent incorrect temperature readings.
🛠️ Installation Notes
Before replacing the terminal board, confirm the complete part number IS200STCIH2A, hardware revision, terminal assignments, connected I/O pack type, and field wiring configuration.
Label all thermocouple cables before removal. Check terminal tightness, wiring polarity, and grounding requirements during installation.
After installation, verify that the Mark VIe controller recognizes the connected I/O hardware. Check temperature input values, diagnostics, alarm status, and sensor feedback before returning the turbine system to normal operation.
⚙️ Commissioning Checklist
