DS200TCEBG1ACD 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 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 “G1ACD”: Basic accuracy (0.12%) + G1 wiring + “ACD” coating package (typically indicates a superior conformal coating formulation – often a thicker, more chemically resistant silicone-acrylic blend with improved moisture barrier and mild solvent resistance compared to standard and ABC coatings)

Key Features

Standard accuracy – ±0.12% for general-purpose temperature monitoring
Enhanced “ACD” coating – superior conformal coating offering improved moisture resistance and mild-to-moderate chemical protection compared to standard and ABC coatings; better suited for environments with occasional chemical splashes or persistent humidity
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
Backward compatible with Mark V and Mark VIe (hot-swap only on VIe Rev D+)

Applications

Coastal power plants with persistent salt spray – where ABC coating may be insufficient but full military-grade is unnecessary
Industrial environments with regular chemical fumes – moderate protection against mild corrosives and solvents
High-humidity tropical installations – where moisture resistance is critical
Paper and pulp mills with chemical exposure – better protection than ABC for chlorine and caustic environments
Food processing plants with frequent washdowns – where cleaning chemicals are used regularly

Comparison with Competitors

Selection Tips

Choose the DS200TCEBG1ACD if you need better environmental protection than ABC (superior moisture and mild chemical resistance) with basic accuracy in a G1 cabinet
For standard environments, the DS200TCEBG1 is more economical
For ABC-level protection, consider DS200TCEBG1ABC if available
For severe chemical exposure, upgrade to DS200TCEAG1BTF (PTFE) or DS200TCEAG1BJE (military-grade) – both also offer higher accuracy
For high accuracy needs with the same coating, use DS200TCEAG1B with ACD coating (if available)
Verify the exact coating specification – “ACD” may indicate specific GE internal coating codes; confirm with your supplier
Source refurbished units with coating inspection and thickness verification

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 – ACD coating may resist some solvents, but acetone or MEK can still degrade it
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 “G1ACD – ENHANCED COATING” to ensure proper handling and prevent confusion with ABC or standard boards
