DS200TCEBG1A GE

Technical Parameters

Manufacturer: GE
Series: Mark V / Mark VIe
Channels: 16 differential
Input Range: -10 mV to +100 mV (Type J/K/T/E)
Cold Junction: Single onboard sensor with improved linearization (better than standard G1)
Isolation: 1500V AC
Accuracy: ±0.10% at 25°C, ±0.18% across full temperature range
Sampling: 5 Hz sequential
Temp Range: -25°C to +65°C (operating) – slightly wider than standard G1, -40°C to +85°C (storage)
Mounting: VME rack
Suffix “G1A”: Basic accuracy with improved cold-junction compensation + G1 wiring configuration + basic diagnostics (open/short only) + fixed firmware

Key Features

Improved accuracy – ±0.10% vs ±0.12% on standard G1, bridging the gap between basic and high-accuracy boards
Better cold-junction compensation – enhanced linearization for more stable readings across ambient temperature changes
Standard sampling – 5 Hz for typical turbine monitoring applications
G1 wiring configuration – standard channel-to-terminal mapping matching most GE cabinets
Basic self-diagnostics – open-circuit and short-circuit detection per channel
Simple swap – no firmware changes required in most Mark V systems
LED status per channel + board health
Standard conformal coating for moisture/dust resistance
Backward compatible with Mark V and Mark VIe (hot-swap only on VIe Rev D+)

Applications

Gas turbine exhaust monitoring – where ±0.10% accuracy provides a measurable improvement over standard G1 without the cost of high-accuracy boards
Steam turbine bearing temperature monitoring – improved stability for critical protection points
Compressor discharge temperature – better precision for performance tracking
HRSG temperature monitoring – enhanced accuracy for thermal efficiency calculations
Legacy system upgrades – drop-in replacement for standard G1 boards with modest accuracy improvement

Comparison with Competitors

Selection Tips

Choose the DS200TCEBG1A if you need slightly better accuracy than standard G1 (±0.10% vs ±0.12%) but do not require the full high-accuracy (±0.08%) and faster sampling (10 Hz) of the TCEA series
For basic monitoring where ±0.12% is acceptable, the DS200TCEBG1 is more economical
For high accuracy and faster sampling, upgrade to the DS200TCEAG1B
For G2 cabinets, choose the DS200TCEBG2A (if available) or DS200TCEAG2B for enhanced accuracy

Precautions

ESD sensitive – use wrist strap
Power down for Mark V removal (no hot-swap)
Torque terminals to 0.5 N·m max
Do not exceed -25°C to +65°C operating range
Calibrate every 24 months – accuracy spec depends on valid calibration
Ground shields only at the board end
Verify thermocouple type – hardware optimized for J/K (T/E reduces accuracy to ±0.20%)
Label clearly – mark board and slot as “G1A – IMPROVED ACCURACY” to distinguish from standard G1 boards
