DS200TCEAG1BTF GE Mark V

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: -40°C to +70°C (operating) – extended low end vs standard G1B, -55°C to +85°C (storage)
Mounting: VME rack
Suffix “G1BTF”: Enhanced accuracy (G1B) + Teflon (PTFE) conformal coating (TF) – specialized fluoropolymer coating offering superior chemical, moisture, and non-stick properties

Key Features

Enhanced accuracy – ±0.08% for critical temperature measurements
Faster sampling – 10 Hz for responsive monitoring
Teflon (PTFE) conformal coating – superior chemical resistance (acids, bases, solvents), extreme moisture barrier, low friction surface, excellent dielectric properties, and temperature stability from -55°C to +150°C
Extended low-temperature range – operates down to -40°C, suitable for arctic or unheated 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
Backward compatible with Mark V and Mark VIe (hot-swap only on VIe Rev D+)

Applications

Chemical processing plants – where strong acids, bases, and aggressive solvents are present; PTFE coating resists chemical attack that degrades standard acrylic coatings
Pharmaceutical manufacturing – cleanroom environments requiring non-contaminating, non-stick surfaces
Paper and pulp mills – high-moisture, high-chlorine environments
Food and beverage processing – where cleaning chemicals (chlorine, caustics) are used regularly
Coastal power plants – superior moisture barrier against salt spray
Laboratory and test cells – environments with solvent vapors where standard coatings degrade
Turbine installations near chemical storage areas – long-term protection against chemical fumes

Comparison with Competitors

Selection Tips

Choose the DS200TCEAG1BTF if your environment has aggressive chemicals (acids, bases, solvents) that would degrade standard coatings, and you require high accuracy (±0.08%)
For extreme corrosion (H₂S, salt spray) rather than chemical exposure, the DS200TCEAG1BJE (military-grade coating) may be better suited
For the same chemical resistance but without high-accuracy needs, consider the DS200TCDAG1B variant with PTFE coating (if available)
For standard environments, the DS200TCEAG1B is more economical
Verify existing wiring is 2-wire standard – this board uses G1-series terminal mapping
Source from suppliers who can provide PTFE coating verification and thickness measurement

Precautions

ESD sensitive – use wrist strap; PTFE coating does not eliminate ESD risk
Power down for Mark V removal (no hot-swap)
Torque terminals to 0.5 N·m max – over-tightening cracks PCB traces
Do not exceed -40°C to +70°C operating range – PTFE coating is stable beyond this, but components are not
PTFE coating is slippery – handle with care to avoid dropping the board; use non-slip work surfaces
Avoid scratching the coating – PTFE can be abraded; scratches expose the PCB underneath
No rework or soldering – PTFE coating is near-impossible to remove cleanly in the field; repairs are not recommended
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 cables clearly as “G1BTF – PTFE COATED”
Store spares at 15°C–35°C, 40%–60% RH; avoid direct contact with sharp objects that could scratch the coating
