DS200TCEBG1BAA

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 +65°C (operating) – extended upper limit vs standard G1 (60°C), -40°C to +85°C (storage)
Mounting: VME rack
Suffix “G1BAA”: Basic accuracy (0.12%) + G1 wiring + extended upper temperature limit (65°C) + “AA” coating package (typically indicates a specific conformal coating – often an enhanced acrylic or silicone blend with improved moisture resistance, generally comparable to or slightly better than the “ABC” coating in moisture protection but with different chemical resistance properties)

Key Features

Standard accuracy – ±0.12% for general-purpose temperature monitoring
Extended upper temperature limit – operates up to 65°C (vs 60°C on standard G1), suitable for cabinets with limited cooling
“AA” specialized coating – enhanced conformal coating offering improved moisture resistance and some chemical protection compared to standard acrylic; typically formulated for high-humidity or mildly corrosive environments
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

High-humidity tropical power plants – where moisture resistance is critical and cabinet temperatures reach 60-65°C
Coastal installations with moderate salt exposure – enhanced coating with extended temperature capability
Industrial environments with occasional chemical fumes – where both heat and mild corrosion are concerns
Paper and pulp mills – high humidity and mild chemical exposure
Food processing facilities – frequent washdowns with elevated ambient temperatures

Comparison with Competitors

Selection Tips

Choose the DS200TCEBG1BAA if your G1 cabinet operates at 60-65°C with moderate moisture/humidity concerns – combining extended temperature with enhanced coating in one board
For the same environment with higher accuracy needs, consider DS200TCEAG1B with AA coating (if available)
For standard environments (≤60°C) without special coating, the DS200TCEBG1 is more economical
For severe chemical exposure with extended temperature, upgrade to DS200TCEAG1BTF (PTFE) or DS200TCEAG1BJE (military-grade)
For G2 cabinets with similar requirements, choose DS200TCEBG2BAA (if available)
Verify the exact “AA” coating specification with your supplier, as the code may have specific GE internal meanings

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 +65°C operating range – exceeding 65°C reduces component life
Avoid damaging the coating – scratches compromise protection
Use isopropyl alcohol only for cleaning – the “AA” coating may be vulnerable to stronger solvents; confirm with GE documentation
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 “G1BAA – EXTENDED TEMP / AA COATING” to ensure proper handling and prevent confusion with standard boards
Monitor cabinet temperature – if consistently near 65°C, consider improving cooling to extend component life
