Description
These operating instructions describe how to install and use the National Instruments FP-AI-111 and cFP-AI-111 analog input modules (referred to inclusively as the [c]FP-AI-111). For information about configuring and accessing the [c]FP-AI-111 over a network, refer to the user manual for the FieldPoint network module you are using.
The [c]FP-AI-111 is a FieldPoint analog input module with the following features:
• 16 single-ended analog current input channels
• Three input ranges: ±20, 0–20, and 4–20 mA
• 16-bit resolution
• Three filter settings: 50, 60, and 500 Hz
• Hot swappable
• 2,300 Vrms transient overvoltage protection
• –40 to 70 °C operation
The FP-AI-111 mounts on a FieldPoint terminal base (FP-TB-x), which provides operating power to the module. Installing the FP-AI-111 onto a powered terminal base does not disrupt the operation of the bank.
To install the FP-AI-111, 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-111 module.
2. Align the FP-AI-111 alignment slots with the guide rails on the terminal base.
3. Press firmly to seat the FP-AI-111 on the terminal base. When the module is firmly seated, the terminal base latch locks it into place.
The cFP-AI-111 mounts on a Compact FieldPoint backplane (cFP-BP-x), which provides operating power to the module. Installing the cFP-AI-111 onto a powered backplane does not disrupt the operation of the bank.
To install the cFP-AI-111, refer to Figure 2 and complete the following steps:
1. Align the captive screws on the cFP-AI-111 with the holes on the backplane. The alignment keys on the cFP-AI-111 prevent backward insertion.
2. Press firmly to seat the cFP-AI-111 on the backplane.
3. Using a number 2 Phillips screwdriver with a shank of at least 64 mm (2.5 in.) length, tighten the captive screws to 1.1 N ⋅ m
