AI module, 8-CH, 2-3-4 Wire RTDs
ABB AI03 AI module 8-CH
ABB AI03 AI module 8-CH
The AI03 Analog Input module processes up to 8 group isolated, RTD temperature input field signals. Each channel supports 2/3/4 Wire RTD wiring an is independently configurable for any of the supported RTD types. FC 221 (I/O Device Definition) sets AI module operating parameters and each input channel is configured using FC 222 (Analog Input Channel) to set indivdual input channel parameters such as engineering units, High/Low alarm limits, etc.
A/D resolution of each channel is 16 bits with polarity. The AI03 module has 4 A/D converters, each serving 2 input channels. The module will update 8 input channels in 450 msecs.
The AI03 module is automatically calibrated, hence there is no need for manual calibration.
Features and benefits:
1: 8 independently configurable channels supporting RTD types:
2: 100 Ω Platinum U.S. Lab & Industry Standard RTD
3: 100 Ω Platinum European Standard RTD
4: 120 Ω Nickel RTD, Chinese 53 Ω Copper
5: A/D resolution 16-Bit (with polarity)
6: A/D update of all 8 Channels in 450 msecs
7: Accuracy is ±0.1 % of Full Scale Range where FSR = 500 Ω
