IS200TRPLH1A GE

Product Parameters

Advantages & Key Features

• Low-Voltage Transducer Support: IS200TRPLH1A provides selectable 5 VDC, 10 VDC, or 15 VDC outputs per channel, accommodating a wide range of low-voltage transducers.

• High Channel Density: 16 isolated transducer power channels in a single VME slot—double the density of competing modules.

• Programmable Output Voltage: Per-channel adjustable voltage selection via GE ToolboxST.

• High Accuracy Regulation: ±0.1% voltage regulation ensures stable transducer operation.

• Comprehensive Diagnostics: Overcurrent, short-circuit, under/over-voltage, and open-circuit detection per channel enable predictive maintenance.

• Low Ripple/Noise: < 10 mV peak-to-peak ripple ensures clean power for sensitive transducers.

• Opto-Isolation: 1500 VAC isolation protects the Mark VIe backplane from field wiring faults.

• ToolboxST Integration: Full configuration, monitoring, and diagnostics via GE ToolboxST.

• Drop-In Replacement: Direct replacement for earlier GE low-voltage transducer power terminal boards.

Application Fields

• Gas & Steam Turbines (GE Frame 6B/7EA/9E/HA): Powering low-voltage pressure transmitters, temperature transmitters, position transducers, and vibration sensors.

• Combined Cycle Plants: Powering HRSG low-voltage pressure and temperature transmitters.

• Compressor Stations: Powering low-voltage suction/discharge pressure transmitters and temperature transmitters.

• Aeroderivative Turbines: Powering low-voltage fuel flow, oil pressure, and temperature transmitters.

• General Industrial: Powering low-voltage field transducers requiring 5 V, 10 V, or 15 V excitation.

Comparison with Competing Products

Key Advantage: IS200TRPLH1A provides 16 isolated low-voltage transducer power channels—double the density of competing modules—with programmable 5/10/15 VDC output, high accuracy regulation (±0.1%), and comprehensive diagnostics, making it ideal for powering low-voltage field transducers in turbine applications.

Selection Guidelines & Recommendations

• Voltage Selection: Configure per-channel output voltage (5 V, 10 V, or 15 VDC) in GE ToolboxST based on transducer requirements.

• Channel Count: Determine number of transducers requiring low-voltage power—up to 16 per board.

• Current Requirements: Verify each transducer’s current draw does not exceed 50 mA per channel.

• Diagnostic Configuration: Enable overcurrent, short-circuit, and under/over-voltage monitoring for critical transducers.

• Controller Firmware: Requires Mark VIe processor firmware v7.5 or later.

• Wiring Guidelines: Use shielded twisted-pair cables. Maintain shield grounding only at the Mark VIe cabinet end.

• Spare Strategy: Keep one spare per turbine; lead times 6–8 weeks.

• Retrofit: Direct replacement—regenerate configuration in GE ToolboxST.

Important Cautions

1. No Hot-Swap: De-energize rack before insertion/removal.

2. Power Polarity: Observe correct polarity for transducer connections—reverse polarity may damage field devices.

3. Voltage Verification: Verify transducer voltage requirements before powering up—incorrect voltage may damage devices.

4. Current Limit: Do not exceed 50 mA per channel—overcurrent protection will trip and latch.

5. Short-Circuit: If a short is detected, the channel will latch off. Clear the fault and reset via GE ToolboxST.

6. Grounding: Connect AGND to Mark VIe system ground at single star point.

7. Shield Termination: Ground transducer cable shields only at cabinet end.

8. ESD Handling: Use grounded wrist straps; field repair not possible.

9. Channel Mapping: With 16 channels, verify field wiring maps to correct ToolboxST channel numbers.
