I/O Systems - SD Series I/OcAI01

The cAI01 Analog Input module processes up to 8 high level, group isolated, analog input field signals. Each channel is independently configurable for either 4 to 20 mA or 1 to +5 VDC ranges. 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 configurable from 12 to 16 bits with polarity. The cAI01 module has one A/D converter for all 8 input channels. The module will update all 8 input channels in 100 msecs.

The cAI01 module will also detect an open circuit in less than 5 seconds.
