GE DS200TCRAG1ACC

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
Isolation: 1500V AC
Accuracy: ±0.12% at 25°C, ±0.20% across full temperature range
Sampling: 5 Hz sequential
Operating Temp: -25°C to +60°C
Storage Temp: -40°C to +85°C
Mounting: VME rack
Suffix “G1ACC”: Basic accuracy (0.12%) + G1 wiring + basic diagnostics (open/short only) + enhanced cold-junction compensation + “CC” mid-grade coating (enhanced conformal coating offering good moisture resistance and mild-to-moderate chemical protection – comparable to “CB” or similar grades)

Key Features

Basic accuracy – ±0.12% for general-purpose temperature monitoring
Enhanced cold-junction compensation – better linearization across ambient variations than standard G1 variants
“CC” mid-grade coating – good moisture resistance and mild-to-moderate chemical protection; suitable for humid or mildly chemically exposed environments
Basic self-diagnostics – open-circuit and short-circuit detection per channel
Standard sampling – 5 Hz for typical turbine monitoring applications
G1 wiring configuration – standard channel-to-terminal mapping matching most GE cabinets
Simple swap – no firmware changes required in most Mark V systems
LED status per channel + board health
Backward compatible with Mark V and Mark VIe (hot-swap only on VIe Rev D+)

Applications

Coastal power plants with moderate salt spray and G1 wiring – improved moisture protection with enhanced compensation
Chemical processing facilities with occasional fume exposure – mild-to-moderate chemical resistance
High-humidity tropical installations – robust moisture barrier with improved ambient stability
Paper and pulp mills with G1 cabinets – humid environments with mild chemical exposure
Compressor monitoring in chemically exposed areas – environmental protection with basic accuracy

Comparison with Competitors

Selection Tips

Choose the DS200TCRAG1ACC for basic temperature monitoring in G1 cabinets where improved cold-junction stability and mid-grade coating protection are beneficial – a cost-effective solution for humid or mildly chemically exposed environments
For standard compensation with the same coating, consider the DS200TCRAG1CC (if available)
For better chemical resistance with similar specs, consider premium coatings (EC, DE) if available
For higher accuracy (±0.08%) and faster sampling (10 Hz) with similar coating, upgrade to the DS200TCQAG1ACC (if available)
For extended temperature (65°C) with similar features, consider DS200TCRAG1BCC (if available)
Source refurbished units with coating inspection verification and cold-junction compensation validation

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
Avoid damaging the coating – scratches compromise protection
Use isopropyl alcohol only for cleaning – “CC” coating resists some solvents but avoid acetone/MEK; confirm compatibility with GE documentation
Calibrate every 24 months – accuracy spec depends on valid calibration
Ground shields only at the board end
Verify thermocouple type – optimized for J/K (T/E reduces accuracy to ±0.20%)
Label clearly – mark board and slot as “TCRAG1ACC – ENH CJC/CC COAT” to distinguish from standard boards
