FieldDAQ can be mounted on any substrate in any orientation if the ambient temperature is 75 °C or less.

However, to ensure proper functionality during use above 75 °C, you must mount the FieldDAQ device in the reference mounting configuration shown in the following figure. Observe the following guidelines to mount the FieldDAQ device in the reference mounting configuration.

Figure 9. Reference Mounting Configuration


  1. Vertical mounting orientation.
  2. Mount the FieldDAQ device directly to a metallic surface that is at least 1.6 mm (0.062 in.) thick and extends a minimum of 76.2 mm (3 in.) beyond all edges of the device.
  3. Observe the cooling dimensions in Mounting Requirements.
  4. Allow space for cabling clearance according to the Mounting Requirements.

Before using any mounting methods, record the serial number from the back of the FieldDAQ device so that you can identify it in MAX. You will be unable to read the serial number after you mount the device.

Mounting Requirements

Your installation must meet the following requirements for cooling and cabling clearance. Allow 76.2 mm (3.00 in.) on all sides of the device for air circulation, as shown in the following figure.

Figure 10. Cooling Dimensions


Allow the appropriate space in front of the device for cabling clearance, as shown in the following figure.

Figure 11. Cabling Clearance


Measure the ambient temperature at each side of the FieldDAQ device, 76.2 mm (3.00 in.) from the side and 25.4 mm (1.00 in.) forward from the rear of the device. Refer to the following figures for ambient temperature locations for horizontal and vertical mounting configurations.

Mounting the Device Directly on a Flat Surface

For environments with high shock and vibration, NI recommends mounting the FieldDAQ device directly on a flat, rigid surface using the mounting holes on the device. This mounting technique requires four M5 or 10-32 pan head or socket head cap screws appropriate for the surface.

Complete the following steps to mount the FieldDAQ device directly on a flat surface.

  1. Prepare the surface for mounting the device using the surface mounting dimensions.
    Figure 14. Surface Mounting Dimensions


  2. Align the device on the surface.
  3. Fasten the device to the surface using the M5 or 10-32 screws. Tighten the screws to a maximum torque of 2.5 N · m (25.0 lb · in.).
    Figure 15. Fastening the Device to the Surface


Alternate Mounting Configurations

The maximum operating temperature of 85 °C may be reduced for any mounting configuration other than the reference mounting configuration. A 10 °C (18 °F) reduction in maximum operating temperature is sufficient for most alternate mounting configurations. Follow the mounting requirements for all mounting configurations.

The published accuracy specifications, although not guaranteed for alternate mounting configurations, may be met depending on the system power and the thermal performance of the alternate mounting configuration.

Contact NI for further details regarding the impact of common alternate mounting configurations on maximum operating temperature and accuracy.

Mounting the Device on a DIN Rail

The FD-11960 DIN rail mounting kit is an accessory you can use to mount a FieldDAQ device to a DIN rail. The hardware in the FD-11960 DIN rail mounting kit includes a bracket panel, a DIN rail clip, four M5 x 10 mm screws, four M5 washers, and two 8-32 x 1/4 in. screws.

Complete the following steps to install a FieldDAQ device onto a DIN rail using the FD-11960 DIN rail mounting kit.

  1. Attach the FieldDAQ device to the bracket panel using the included M5 x 10 mm screws and M5 washers. The front of the bracket panel, which includes an outline of the FieldDAQ device, should be attached to the back of the FieldDAQ device.
  2. Attach the DIN rail clip to the FieldDAQ device and bracket panel using the 8-32 x 1/4 in. screws included in the kit. Tighten the screws to a maximum torque of 1.3 N · m (11.5 lb · in.).
