DS200TCEAG2B 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 precision sensor with enhanced linearization
Isolation: 1500V AC
Accuracy: ±0.08% at 25°C, ±0.15% across full temperature range
Sampling: 10 Hz sequential
Temp Range: -30°C to +70°C (operating), -40°C to +85°C (storage)
Mounting: VME rack
Suffix “G2B”: Enhanced accuracy + G2 wiring configuration (different channel-to-terminal mapping than G1 series) + basic diagnostics (open/short only) + fixed firmware

Key Features

Enhanced accuracy – ±0.08% for critical temperature measurements
Faster sampling – 10 Hz for responsive monitoring compared to standard G series
G2-specific wiring configuration – unique channel-to-terminal mapping that matches specific GE cabinet wiring standards; direct drop-in for G2-configured systems
Extended upper temperature limit – operates up to 70°C for hotter cabinets
Improved cold-junction compensation – better linearization across ambient variations
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

Legacy gas turbine retrofits – where existing field wiring was terminated for G2-series terminal assignments, and higher accuracy (±0.08%) is required
Steam turbine bearing temperature monitoring – in cabinets with G2 wiring standards requiring precision measurements
Pipeline compressor stations – with G2-configured cabinets originally delivered with specific pinouts
Industrial cogeneration plants – where the OEM specified G2 wiring for thermocouple terminations
Critical monitoring applications – where 0.08% accuracy justifies maintaining the existing G2 wiring instead of converting to G1

Comparison with Competitors

Selection Tips

Choose the DS200TCEAG2B only if your cabinet uses G2 wiring configuration and you require enhanced accuracy (±0.08%) – this board combines precision with G2 pinout compatibility
For G2 systems where ±0.12% accuracy is acceptable, the DS200TCDAG2B is more economical
For G1 systems requiring the same accuracy, use the DS200TCEAG1B
If you are rewiring the cabinet, consider converting to G1 and using the DS200TCEAG1B or DS200TCDAG1ADA for advanced diagnostics
Verify existing wiring pinout against G2 standard – use the correct G2 terminal blocks
Source refurbished units with G2 pinout verification in the 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 -30°C to +70°C operating range
Pinout critical – the G2 mapping differs from G1; installing this board in a G1 cabinet will scramble channel readings; verify cabinet wiring before installation
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 ±0.15%)
Label clearly – mark board and slot as “G2 CONFIGURATION – HIGH ACCURACY” to prevent future miswiring
Do not mix G1 and G2 boards without verifying terminal block compatibility in the same rack
