I/O Systems - SDe Series I/OAI16e

The AI16e Universal Analog Input module processes up to sixteen (16) high level, CH-2-CH isolated, analog input field signals. Each channel is independently configurable for high level (4 to 20 mA or 1 to +5 VDC), RTD, mV and TC analog input signal ranges.

FC 221 (I/O Device Definition) sets AI module operating parameters and each input channel is configured using FC 222 (Analog Input CH) to set indivdual input channel parameters such as engineering units, High/Low alarm limits, etc.

Each input channel has a dedicated A/D converter that provides 24 bit resolution with polarity. The AI16e module will update all 16 input channels in 100 msecs.

In current mode, the AI16e module sprovides short circuit protection by limiting current to a maximum of 96 mA. The AI16e module will also detect an open circuit in less than 400 msec.
