Features:
- Triple Modular Redundancy (TMR) with Hot-Swappable Design
- 16-Channel High-Isolation Analog Input with Flexible Signal Conditioning
- Industrial Hardening for Extreme Turbine Environments
The General Electric IS230TAISH2C IS200TBAIS1CED supports live module replacement without process interruption. The IS230TAISH2C module can be removed and replaced while the Mark VIe system remains operational and the IS200TBAIS1CED terminal board stays field-wired. This minimizes downtime for maintenance and allows TMR configurations where three modules vote on input values, eliminating single points of failure in critical turbine control loops.
The General Electric IS230TAISH2C IS200TBAIS1CED accepts thermocouple, millivolt, and voltage inputs on the same channel set. Each of the 16 differential channels is software-selectable for Type J/K/N/E thermocouples, ±50 mV, ±100 mV, or 0-5 V signals. With 250 Vrms channel-to-channel isolation, the module prevents ground loop interference and protects the control system from field-side faults.
The General Electric IS230TAISH2C IS200TBAIS1CED operates reliably from -40°C to +70°C with full vibration tolerance. The assembly carries ATEX Class I Zone 2 and UL Class I Division 2 hazardous location certifications, making it suitable for gas turbine enclosures, compressor stations, and outdoor skid-mounted installations. The IS200TBAIS1CED adds per-channel 200 mA PTC fuses and TVS surge suppression for field wiring protection.
The IS230TAISH2C IS200TBAIS1CED General Electric TMR Analog Input DIN Rail Assembly and Terminal Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- ±0.1% Full-Scale Accuracy Reduces Sensor Calibration Margin:The 24-bit resolution and factory calibration of the General Electric IS230TAISH2C IS200TBAIS1CED achieve ±0.1% of full-scale accuracy. For a 0-5V pressure transmitter (0-1000 psi), this represents ±1 psi error – compared to typical ±0.5% (±5 psi) for non-isolated industrial I/O. The tighter margin allows operators to reduce safety calibration allowances, extending maintenance intervals.
- 1000 Hz Per-Channel Scan Rate Captures Transients:Configurable scan rates up to 1 kHz per channel let the module capture fast thermal transients (e.g., turbine startup thermal shock, water induction events). When paired with Mark VIe's high-speed sequence-of-events (SOE) recording, the timestamped input values help root-cause trips and validate mechanical models against actual data.
- 250 Vrms Isolation Eliminates Ground Loop Troubleshooting:Field wiring in turbine enclosures often suffers from stray currents, variable frequency drive noise, and inadequate shielding. The 250 Vrms channel-to-channel and 500 Vrms channel-to-system isolation breaks ground loops without requiring external isolators. This reduces installation cost (no additional signal conditioners) and commissioning time (no chasing phantom floating signals).
- >150,000 Hours MTBF with Hot-Swap Maintainability:The calculated MTBF exceeds 150,000 hours (17+ years continuous operation). When a module eventually requires replacement, the hot-swappable DIN rail design allows a technician to replace the IS230TAISH2C in under 2 minutes without powering down the cabinet or touching field wiring. For plants with availability targets of 99.99%, this reduces mean time to repair (MTTR) from hours to minutes.
- IONet Ring Topology with Sub-20 ms Failover:Dual RJ-45 ports on the IS230TAISH2C support redundant media in a ring configuration. If a cable fails or a switch loses power, the IONet ring recovers within 20 ms – transparent to the controller and fast enough to prevent turbine trip conditions. Module health (PSU, temperature, communication) is reported back to the Mark VIe controller as diagnostic variables.
- Per-Channel Status and Limit Monitoring:Each of the 16 analog inputs includes configurable high-high, high, low, and low-low alarm limits with programmable deadbands. The General Electric IS230TAISH2C IS200TBAIS1CED reports open thermocouple detection (burnout) and rate-of-change alarms through dedicated status bits in the I/O scan. This allows predictive warning of sensor degradation before a critical limit is reached.
- Cold Junction Compensation with Redundancy Option:The onboard PT100 RTD measures terminal temperature for automatic CJC. For critical thermocouple measurements (e.g., turbine inlet temperature), the system can accept an external PT100 on the IS200TBAIS1CED's corner-mounted block as a redundant CJ reference. The module automatically fails over to the secondary sensor if the primary CJ reading deviates.
- Diagnostic LED Indication and Soft Status:Three LED status indicators on the IS230TAISH2C provide immediate field diagnostics: Module OK (green/red), Network A activity, and Network B activity. The module also reports extended diagnostics (internal temperature, power supply voltage, calibration checksum) as Modbus-readable parameters through the controller's toolbox interface.
- Gas Turbine Exhaust Temperature Monitoring:The General Electric IS230TAISH2C IS200TBAIS1CED is specifically optimized for thermocouple arrays measuring turbine exhaust gas temperature (EGT). Its 16 differential channels, PT100 cold-junction compensation, and TMR voting logic make it the standard I/O for GE Frame 5, 6, 7, and 9 turbine exhaust thermocouple systems. The IS200TBAIS1CED's low-thermal-EMF copper terminations (<20 µV) prevent measurement errors from terminal temperature gradients.
- Steam Turbine Bearing and Casing Temperature:For steam turbine supervisory systems, this assembly monitors journal bearing, thrust bearing, and casing metal temperatures using Type K thermocouples. The -40°C to +70°C operating range and high common-mode rejection ensure reliable measurements even when installed inside turbine pedestals or near high-pressure steam chests.
- Compressor Station Vibration and Temperature Skids:In natural gas pipeline compression, the General Electric IS230TAISH2C IS200TBAIS1CED is deployed in auxiliary monitoring skids alongside Vibro-Meter or Bently Nevada vibration systems. It captures bearing temperature trends and process variable analog signals (0-5V from pressure transmitters) for performance calculation and predictive maintenance alarms.
- Combined Cycle Heat Recovery Steam Generator (HRSG):The assembly monitors superheater, evaporator, and economizer tube metal temperatures, along with feedwater temperature transmitters. When used in TMR configuration across three modules, the system maintains control even during single-module failures – critical for HRSG drum level and spray temperature control where a false reading could trip the combined cycle plant.
