The cRIO-906x requires a 9 V to 30 V external power supply. The cRIO-906x filters and regulates the supplied power and provides power for the C Series modules.

The cRIO-9063/9064/9065/9067 has one layer of reverse-voltage protection.

The cRIO-9068 has a primary power input, V1, and a secondary power input, V2. The POWER LED indicates which power input is in use.

Refer to Power LED Indicators for more information about the POWER LED states.

Notice Do not connect the cRIO-9068 secondary power input V2 to a DC mains supply or to any supply that requires a connecting cable longer than 3 m (10 ft). A DC mains supply is a local DC electricity supply network in the infrastructure of a site or building.

What to Use

  • Screwdriver, 2.54 mm (0.10 in.) flathead
  • Primary power supply:
    • (cRIO-9030/9031/9032/9033/9034) 9 V to 30 V, 40 W minimum
    • (cRIO-9035/9036/9037/9038/9039) 9 V to 30 V, 46 W minimum
  • (Optional) Secondary power supply:
    • (cRIO-9068) 9 V to 30 V, 25 W minimum

NI recommends the power supplies listed in the following table for the cRIO-906x.

Power Supply Part Number
cRIO-906x: NI PS-15 Industrial Power Supply (24 V DC, 5 A, 100 V AC to 120 V AC/200 V AC to 240 V AC input) 781093-01
cRIO-9068 only: NI PS-10 Desktop Power Supply (24 V DC, 5 A, 100 V AC to 120 V AC/200 V AC to 240 V AC input) 782698-01

What to Do

Complete the following steps to connect a power supply to the cRIO-906x.

  1. Ensure that your power supply is powered off.
  2. Remove the power connector from the cRIO-906x.
    Caution Do not tighten or loosen the terminal screws on the power connector while the cRIO-906x is powered on.
    Attention Ne pas serrer ou desserrer les vis des bornes sur le connecteur d'alimentation pendant que le cRIO-906x est sous tension.
  3. Connect the primary power supply and optional secondary power supply to the power connector, as shown in the following figure.

    Figure 14. cRIO-9068 Power Connections


    Note The C terminals are internally connected to each other.
  4. Tighten the terminal screws on the power connector to 0.20 N · m to 0.25 N · m (1.8 lb · in. to 2.2 lb · in.) of torque.
  5. Install the power connector on the front panel of the cRIO-906x.
  6. Tighten the power connector screw flanges to 0.20 N · m to 0.25 N · m (1.8 lb · in. to 2.2 lb · in.) of torque.
  7. Power on the power supply. cRIO-9068: Power on the primary power supply (cRIO-906x) and optional secondary power supply.
    When you power on the cRIO-906x for the first time, the device boots into safe mode. The POWER LED illuminates, the STATUS LED illuminates briefly, and then the STATUS LED blinks twice every few seconds, indicating the controller does not yet have software installed.
