GE DS200TCCAG1BAA
TC2000 Analog I/O Terminal Board for GE Mark V Speedtronic systems. It handles mixed analog signal acquisition and output with 16-bit precision and high-speed refresh.
- Technical Specifications: 16 differential analog input channels (configurable 4–20 mA / ±10 V / RTD / TC); 16 isolated analog output channels (4–20 mA / ±10 V); 16-bit ADC/DAC; ±0.1 % full-scale accuracy; 2 ms channel refresh; 2500 Vrms channel-to-backplane isolation; VME P1/J1 + 50-pin ribbon interface supporting TCQA/VCMI parallel bus; 24 VDC (18–36 V) supply, 12 W typical; –30…+65 °C operating, –40…+85 °C storage; 363 × 124 × 146 mm, 2.9 kg; UL E207685, CE, ATEX Zone 2, SIL2.
Detailed content
- Functional Features: On-board 80196 microprocessor with PROM supports real-time scaling, linearization, and fault diagnosis; programmable gain amplifiers with 50/60 Hz notch filtering and cold-junction compensation; thermocouple measurement error ≤ ±0.5 °C; RTD 3-wire lead resistance auto-compensation; full-temperature accuracy better than ±0.1 % FS; 30 V mis-wiring protection; ISA-S71.04 G3 conformal coating for salt-fog environments (250,000 h MTBF).
- Application Scenarios: Critical loops in gas turbine blade temperature monitoring and steam valve position feedback; fuel valve and IGV angle high-speed modulation in Mark V controllers; full-field signal scanning and output refresh within 2 ms.
- Structural Characteristics: Modular hot-swappable design — can be withdrawn and replaced while the Mark V cabinet remains energized; calibration parameters auto-download within 5 seconds of insertion.
- Installation & Usage Notes: Verify exact model and revision match before replacement; use proper ESD grounding; re-connect all 50-pin and VME connectors fully seated; after hot-swap, allow 5 s for automatic calibration download and verify output current; maintain cabinet temperature within –30…+65 °C.
