Product function

GE IS230SNTCH2A conditions, linearizes, and digitizes thermocouple voltages into calibrated temperature readings. Delivers deterministic, low-latency temperature data over the IONet Ethernet bus to the Mark VIe CPU, supporting real-time control, safety-trip logic, and trend-analysis functions without manual board-level adjustments.

Core supporting modules

I/O Pack Carrier: IS42xPSCAH1B power/carrier assembly providing backplane power and Ethernet interfaces

Controller Module: Mark VIe CPU (e.g., IS200TPROH1C) for data aggregation and control logic

Complementary I/O Boards: RTD inputs (IS220PRTDH1A), analog-pressure inputs (IS220PAICH1A), discrete I/O packs

GE IS230SNTCH2A integrates with this ecosystem.

Extension components

Pluggable Terminal Blocks: Screw-clamp blocks keyed to prevent mis-insertion, available in shielded variants

DIN-Rail & Panel Mount Kits: Adapter clips and angle brackets for 35 mm rail or panel installation

Shielding Accessories: Cable-shield clamps and ferrite beads for EMI/RFI suppression on thermocouple runs

Calibration Fixtures: External cold-junction and span-adjust testers for on-site verification

All accessories compatible with GE IS230SNTCH2A.

Software support

Configuration & Calibration:

Thermocouple type and filter settings defined via GE ControlST™/ToolboxST™ templates

On-line calibration wizard for zero-offset and span adjustments per channel

Diagnostics & Monitoring:

Open-circuit, short-circuit, and out-of-range alarms reported via HMI and OPC-DA tags

Self-test on power-up with diagnostic flags accessible in controller diagnostics

Firmware Updates: Delivered as part of Mark VIe system releases; applied through ToolboxST™

Documentation: Detailed in the GE Mark VIe/VIeS I/O Installation Guide and Thermocouple Input Module Reference Manual
