GE DS200TCEBG1

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 standard sensor
Isolation: 1500V AC
Accuracy: ±0.12% at 25°C, ±0.20% across full temperature range
Sampling: 5 Hz sequential
Temp Range: -25°C to +60°C (operating), -40°C to +85°C (storage)
Mounting: VME rack
Suffix “G1”: Basic accuracy (0.12%) + G1 wiring configuration + basic diagnostics (open/short only) + fixed firmware

Key Features

Standard accuracy – ±0.12% for general-purpose temperature monitoring
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

General-purpose gas turbine exhaust monitoring – where ±0.12% accuracy is sufficient
Steam turbine bearing temperature monitoring – standard protection with adequate precision
Compressor inlet and discharge temperature – routine monitoring without high-accuracy demands
HRSG temperature monitoring – where tight accuracy is not critical
Legacy systems – direct replacement for original G1 boards with basic specifications

Comparison with Competitors

Selection Tips

Choose the DS200TCEBG1 for basic temperature monitoring in standard G1 cabinets where cost is a priority and enhanced accuracy is not required
If you need higher accuracy (±0.08%) and faster sampling (10 Hz), upgrade to the DS200TCEAG1B
If your cabinet uses G2 wiring, select the DS200TCEBG2 instead
For advanced diagnostics (drift/degradation), consider the DS200TCDAG1ADA (2-wire) or DS200TCDAH1BGD (4-wire)
Source refurbished units with basic functional test report

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 +60°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 “G1 BASIC ACCURACY” to prevent confusion with higher-spec boards
