The AI16ev 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.
The AI16ev Universal Analog Input module is a Form/Fit/Function replacement for ASI23 Analog Signal Input HR i/O modules.
FC 215 (Enhanced Analog Slave Definition) sets the analog input module operating parameter. FC 216 (Enhanced Analog Input Definition) is configured to set individual input channel parameters, such as signal type, engineering units, signal ranges, etc.
Each input channel has a dedicated A/D converter that provides 24-bit resolution with polarity. The AI16ev module will update all 16 input channels in 180 milliseconds.
In current mode, the AI16ev modules provide short-circuit protection by limiting current to a maximum of 96 mA. The AI16ev module will also detect an open circuit in less than 400 milliseconds.
