Description

AI830A is an analog input module from ABB's S800 I/O series, designed for precise and isolated signal acquisition.

Specifications

• Isolation: Groupwise isolated from ground

• Error: Depends on field cable resistance:
  Rerr = R × (0.005 + ∆R / 100)
  Terr°C = Rerr / (R0 × TCR)
  Terr°F = Terr°C × 1.8

• Update cycle time: 150 + 95 × (number of active channels) ms

• CMRR, 50Hz, 60Hz: >120 dB (at 10Ω load)

• NMRR, 50Hz, 60Hz: >60 dB

• Rated insulation voltage: 50 V

• Dielectric test voltage: 500 V a.c.

• Power dissipation: 1.6 W

• Current consumption +5 V Modulebus: 70 mA

• Current consumption +24 V Modulebus: 50 mA
