GE DS3820AIPA

Description

Key Parameters

• Channels: 8 differential (software-configurable per channel)

• Inputs: 4–20 mA, 0–20 mA, 0–5 V, 0–10 V, ±10 V

• Resolution: 16-bit ADC

• Accuracy: ±0.1% FS (25°C); ±0.3% over full temp range

• Isolation: 1500 V RMS (field-to-logic)

• Power: 24 V DC, ≤5 W

• Temp Range: –40°C to +70°C

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

Advantages

• Software-configurable – no jumpers needed; change settings via controller software.

• Hot-swappable – replace without powering down the rack.

• High noise immunity – CMRR > 90 dB, works near VFDs and heavy switchgear.

• Built-in fault detection – alerts for broken wires or sensor shorts.

Applications

• Oil & gas – pressure/temperature monitoring on pipelines.

• Water treatment – flow and level sensing in pump stations.

• Power plants – turbine bearing temps and steam pressure.

• Pharma – cleanroom differential pressure for batch control.

Competitor Comparison

The DS3820AIPA beats basic cards with better diagnostics and flexibility, while undercutting premium models by avoiding unnecessary per-channel isolation costs.

Selection Tips

• Choose DS3820AIPA if you need mixed signal types on one module and software reconfigurability..

• • Verify compatibility with your CPU firmware before ordering.

  • Not suitable for >500 Hz sampling or per-channel isolation requirements.

  Precautions

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

  • Polarity: No reverse-polarity protection – double-check field wiring.

  • Power: Apply backplane power before sensor power.

  • Cooling: Ensure airflow in high-density racks to avoid overheating.

  • Spare: Keep one spare DS3820AIPA for critical loops during maintenance.
