- Page 2 ™ FieldPoint Operating Instructions FP-AI-110 and cFP-AI-110 Eight-Channel, 16-Bit Analog Input Modules These operating instructions describe how to install and use the FP-AI-110 and cFP-AI-110 analog input modules (referred to inclusively as the [c]FP-AI-110). For information about configuring and accessing the [c]FP-AI-110 over a network, refer to the user manual for the FieldPoint network module you are using.
- Page 3 To install the FP-AI-110, refer to Figure 1 and complete the following steps: 1. Slide the terminal base key to either position X (used for any module) or position 1 (used for the FP-AI-110). 2. Align the FP-AI-110 alignment slots with the guide rails on the terminal base.

Figure 7. Current Source with External Power Supply Input Ranges To prevent inaccurate readings, choose an input range such that the signal you are measuring does not exceed either end of the range. © National Instruments Corp. FP-AI-110 and cFP-AI-110... - Page 9 Overranging The [c]FP-AI-110 has an overranging feature that measures a little beyond the nominal values of each range. For example, the actual measurement limit of the ±10 V range is ±10.4 V. The overranging feature enables the [c]FP-AI-110 to compensate for field devices with span errors of up to +4% of full scale.

Ensure that all circuits connected to the module are inaccessible to human touch. Refer to the Safety Isolation Voltage section for more information about isolation on the [c]FP-AI-110. © National Instruments Corp. FP-AI-110 and cFP-AI-110... - Page 11 working voltages of 250 V . Safety standards (such as those published by UL and IEC) require the use of double insulation between hazardous voltages and any human-accessible parts or circuits. Never try to use any isolation product between human-accessible parts (such as DIN rails or monitoring stations) and circuits that can be at hazardous potentials under normal conditions, unless the product is specifically designed for such an application, as is the...
