GE DS3820AIPA1A1A

Key Parameters

• Channels: 8 differential (fixed configuration per suffix code)

• Inputs: 4–20 mA (default) or 0–10 V (check suffix)

• Resolution: 16-bit ADC

• Accuracy: ±0.1% FS (25°C); ±0.3% over –40°C to +70°C

• Isolation: 1500 V RMS field-to-logic

• Power: 24 V DC, ≤5 W

• Diagnostics: Open-circuit, over/under-range, watchdog timer

• Terminal: Specific screw-type or spring-clamp (suffix-dependent)

Advantages

• Pre-configured – reduces setup time; no software calibration needed for basic ranges.

• Hot-swappable – replace without rack power-down.

• High noise immunity – CMRR > 90 dB, stable near VFDs.

• Built-in diagnostics – alerts for broken wires or sensor faults.

Applications

• Oil & gas – pressure/temperature loops

• Water/wastewater – flow and level monitoring

• Power generation – turbine bearing temperature

• Pharma – cleanroom differential pressure

Competitor Comparison

The DS3820AIPA1A1A offers a lower total installed cost compared to software-configurable siblings because it eliminates engineering configuration effort. Against premium cards, it saves budget while delivering the same core 16-bit accuracy and diagnostics.

Selection Tips

• Choose DS3820AIPA1A1A if your signal type (4–20 mA or 0–10 V) is fixed and you want plug-and-play simplicity.

• Verify the exact suffix matches your sensor output – the DS3820AIPA1A1A is not field-reconfigurable.

• Not suitable for mixed signal types on the same module or >500 Hz sampling.

Precautions

• Wiring: Use shielded twisted-pair; ground at module end only.

• Polarity: No reverse protection – check wiring carefully.

• Power sequencing: Apply backplane power before field power.

• Cooling: Ensure airflow in dense racks.

• Spare: Keep one spare DS3820AIPA1A1A for critical loops.
