      Information

      Overview Manuals Configuration & Architecture Certification Info

      Features:

      • 16 independently configurable channels supporting
      • A/D update of all 16 Channels in 100 msecs
      • Accuracy is ±0.1 % of Full Scale Range where FSR = 25 mA or 6.25 VDC
      The RAI02J Redundant Analog Input module processes up to 16 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 individual 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 RAI02J module has one A/D converter for all 16 input channels. The module will update 16 input channels in 100 msecs. In current mode, the RAI02J module supports HART v5.4 instruments and provides short circuit protection by limiting current to a maximum of 96 mA. The RAI02J module will also detect an open circuit in less than 5 seconds.

      The RAI02J ABB Redundant Analog Input module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
