The AI-10 high performance analogue input module for the Series II Remote Terminal Unit provides eight individually isolated input channels, each capable of converting an analogue input signal to a digital signal for use as required by your application. There is also high isolation between the field terminals and the RTU logic.

The AI-10 provides a 24V output for use with loop powered sensors. If the module +24V is used to supply two or more inputs, channel isolation is disabled between those inputs (inputs supplied by the module +24V must use the same ground connection which prevents channel isolation). However, isolation is still maintained between the field and the RTU logic.

The AI-10 is fully compatible with previous analogue input modules (AI-1 and AI-4) allowing for eight input channels of 0-20mA or 4-20mA. However, the input wiring has been changed to allow for enhanced channel isolation and the raw scaling of each input is now 0-32767 instead of 0-32760 due to the greater resolution of the ADC.
