GE IS230SNTCH2A Rev A Thermocouple Input Module | Mark VIe

IS230SNTCH2A Rev A Thermocouple Input Module – GE Mark VIe

This simplex input module reads thermocouple sensors directly. It converts low-level voltage signals into digital data for turbine control. The module ensures precise temperature tracking under extreme conditions.

Technical Specifications

Installation & Commissioning

• Mount the module in a Mark VIe rack. Use the recommended slot.
• Connect thermocouple leads to the terminal block. Follow polarity markings.
• Use shielded cables for long runs. Ground the shield at one end only.
• Power up the rack. The module auto-initialises in 2 seconds.
• Check LED status: green means normal, red indicates fault.

Debugging & Maintenance

• Diagnostic LED shows channel status and communication errors.
• Use ToolboxST software to read live data and configure alarms.
• Hot-swap support: replace the module without shutting down the system.
• Firmware updates via the backplane. No special tools required.
• Routine check: clean the connector pins with isopropyl alcohol.

Compatibility

• Works with all Mark VIe controllers and I/O racks.
• Supports thermocouple types: J, K, T, E, R, S, B, N.
• Fully compatible with GE’s ToolboxST and CIMPLICITY.
• Interfaces with Modicon Quantum via gateway (not direct).

FAQ – Quick Answers

Q: Can I mix thermocouple types on one module?
A: Yes, but each channel must be configured individually in software.

Q: What is the update rate per channel?
A: 250 ms for all 16 channels simultaneously.

Q: Does this module support HART protocol?
A: No, it is a pure thermocouple input module without HART.

Q: Is calibration required after installation?
A: Factory-calibrated. Re-calibrate every 2 years for critical applications.

Q: What happens if the ambient temperature exceeds 70 °C?
A: The module may shut down or give inaccurate readings.
