DS200TCPDG1BDC 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 sensor with enhanced linearization and thermal isolation
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)
Storage: -40°C to +85°C
Mounting: VME rack
Suffix “G1BDC”: Enhanced accuracy (0.08%) + G1 wiring + extended diagnostics (drift, degradation, sense-lead) + extended upper temperature (70°C) + “DC” coating package (mid-to-high grade – typically a thicker, more chemically resistant silicone-acrylic or urethane blend offering superior moisture barrier and moderate solvent/chemical resistance, better than “CC” but not full PTFE or military-grade)

Key Features

• Enhanced accuracy – ±0.08% for critical temperature monitoring

• Extended diagnostics – drift monitoring, degradation prediction, and sense-lead integrity checks

• Faster sampling – 10 Hz for responsive monitoring

• Extended upper temperature limit – operates up to 70°C

• “DC” mid-to-high grade coating – superior moisture resistance and moderate chemical/solvent protection vs standard or “CC” coatings; suitable for persistently humid or chemically exposed environments

• Improved cold-junction compensation – stable readings across ambient variations

• Simple swap – no firmware changes required in most Mark V systems

• LED status per channel + board health, with extended diagnostic indicators

• Backward compatible with Mark V and Mark VIe (hot-swap only on VIe Rev D+)

Applications

• Coastal power plants with persistent salt spray – where cabinet temperatures reach 65–70°C and improved coating durability is needed

• Chemical processing facilities with regular fume exposure – moderate chemical resistance for long-term reliability

• High-humidity tropical installations with washdowns – robust moisture barrier

• Paper and pulp mills – humid, warm environments with chemical exposure

• Food processing plants with aggressive cleaning cycles – better resistance to caustic cleaners than mid-grade coatings

Comparison with Competitors

Selection Tips

• Choose the DS200TCPDG1BDC if you need high accuracy, extended diagnostics, 70°C operation, and improved chemical/moisture resistance beyond mid-grade coatings – an excellent balance for warm, chemically exposed G1 environments

• For the same features with standard coating (less protection), consider DS200TCPDG1B

• For severe chemical/corrosion exposure with similar specs, upgrade to DS200TCPDG1BJE (military-grade) or DS200TCPDG1BTF (PTFE) if available

• For 4-wire long-distance needs with diagnostics, consider DS200TCDAH1BGD (lower accuracy at ±0.10%)

• Verify exact “DC” coating specification with your supplier – coating codes may have specific GE internal meanings

• Source refurbished units with coating inspection verification and diagnostic test 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 -30°C to +70°C operating range – exceeding 70°C reduces component life

• Avoid damaging the coating – scratches compromise protection

• Use isopropyl alcohol only for cleaning – confirm solvent compatibility with GE documentation for “DC” coating; it may resist some solvents but avoid acetone/MEK

• Calibrate every 24 months – extended diagnostics depend on a valid baseline calibration

• Ground shields only at the board end

• Verify thermocouple type – optimized for J/K (T/E reduces accuracy to ±0.15%)

• Monitor diagnostic logs – drift warnings indicate sensor aging; plan proactive replacement

• Label clearly – mark board and slot as “G1BDC – PRECISION/DIAG/ENH COATING” to ensure proper handling and prevent confusion with standard or lower-grade coated boards

• Monitor cabinet temperature – if consistently near 70°C, consider cooling improvements or a variant with wider range (-40°C to +75°C) if needed
