Connecting the cRIO-9082 to Power
The cRIO-9082 requires a 9 V to 30 V external power supply. The cRIO-9082 filters and regulates the supplied power and provides power for the C Series modules. The cRIO-9082 has a primary power input, V1, and a secondary power input, V2.
The POWER LED on the cRIO-9082 indicates which power input is in use, as shown in the following table.
LED Color | LED Pattern | Indication |
---|---|---|
Green | Solid | The cRIO-9082 is powered from the V1 input. |
Yellow | Solid | The cRIO-9082 is powered from the V2 input. |
— | Off | The cRIO-9082 is powered off. |
Caution Do not connect 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
- Ferrite
- Screwdriver, 2.54 mm (0.10 in.) flathead
- Primary power supply, 9 V to 30 V, 46 W minimum
- (Optional) Secondary power supply, 9 V to 30 V, 46 W minimum
NI recommends the power supplies listed in the following table for the cRIO-9082.
Power Supply | Part Number |
---|---|
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 |
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-9082.
- Ensure that your power supply is powered off.
-
Install the ferrite on the negative and positive leads of the power supply, as shown in the following figure.
Figure 1. Installing a Ferrite on the Power Leads
- Pass the leads through the ferrite twice, leaving 50 mm to 75 mm (2 in. to 3 in.) between the ferrite and the end of the leads.
- Close the ferrite around the leads.
-
Remove the power connector from the cRIO-9082.
Caution Do not tighten or loosen the terminal screws on the power connector while the cRIO-9082 is powered on.
-
Connect the primary power supply and optional secondary power supply to the power connector.
Note The C terminals are internally connected to each other.
- 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.
- Install the power connector on the front panel of the cRIO-9082.
- 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.
- Power on the primary power supply and optional secondary power supply.
