Overview
The GE IS230SRTDH2A, also identified by the base model IS230SRTDH2A, is an RTD terminal board for the GE Mark VIe turbine control system. It provides field termination for eight resistance temperature detector (RTD) inputs and connects to a PRTD or VRTD I/O processor. The board supports DIN-rail or flat mounting configurations and uses high-density Euroblock terminal connectors for field wiring.

RTD Signal Termination and I/O Interface
The IS230SRTDH2A terminates field RTD wiring before the temperature signals reach the associated I/O processor. Its eight input channels support the connection of multiple temperature measurement points within the turbine control system.
The Euroblock terminals provide individual field wiring connections. Therefore, installers should verify terminal assignments against the applicable GE wiring documentation before connecting RTD sensors.
The board connects to a PRTD or VRTD processor. The exact sensor resistance ranges, wiring configurations, and supported RTD types must be confirmed from the relevant system documentation.
Frequently Asked Questions

Field Installation Guidelines
- Verify the complete board model and hardware revision against the system drawings.
- Isolate the relevant equipment and follow site electrical safety procedures before wiring.
- Confirm RTD sensor type, channel assignments, and wiring configuration using the applicable GE documentation.
- Route RTD signal cables separately from high-current conductors and switching circuits where practical.
- Apply cable shielding and grounding according to the system grounding plan to reduce electrical interference.
- Inspect Euroblock terminals for secure conductor termination and correct channel identification.
- Verify field wiring continuity and processor compatibility before restoring operation.
