The NI 9505 module is a full H-bridge servo motor drive for direct connectivity to actuators such as fractional horsepower brushed DC servo motors, relays, lamps, solenoids, and valves. With its low power consumption and small size, combined with the reconfigurability and performance of the field-programmable gate array (FPGA), you can create intelligent, energy-efficient control systems using the NI LabVIEW graphical system design platform. The NI 9505 delivers continuous current of up to 5 A at 40 °C (or 1 A at 70 °C) at 30 V. To increase the output power of the module, National Instruments offers an additional screw-terminal accessory you can use in place of the standard screw terminal included with the NI 9505 module. With the NI 9931 screw-terminal accessory, the NI 9505 can deliver a maximum current of 7.3 A at 40 °C (or 1 A at 70 °C).

The NI 9505 benefits electronics engineers designing consumer appliances, industrial control engineers designing small- to medium-sized machines, and automotive engineers working on rapid prototyping applications.

System Assurance Programs

Reduce your setup time and total cost of ownership, and get a system you can use out of the box with National Instruments system assurance programs. System assurance programs include:

  • Installation and integration test of all individual hardware
  • Courtesy installation of system driver sets and application development environments
  • Three-year warranty and calibration coverage
  • Custom documentation plus a custom restore and startup utility

This service is only available for PXI, NI CompactRIO, and NI Compact FieldPoint systems.

Extended Warranties

National Instruments designs and manufactures all products to minimize failures, however unexpected failures can still occur. Extended warranties provide a fixed economical price at the time of system purchase, covering any repair costs for up to three years. In addition, they offer the following benefits:

  • Significant cost savings compared to individual repair incidents
  • Fault location, diagnostics, and repair by NI any time the system product fails
  • All parts and labor costs covered as well as any adjustments needed to restore the hardware to manufacturing specifications

For more information about your warranty options:

Calibration

NI recognizes the need to maintain properly calibrated devices for high-accuracy measurements. NI provides manual calibration procedures, services to recalibrate your products, and automated calibration software to calibrate many NI measurement products.

Training

NI training is the fastest, most certain route to productivity with NI tools and successful application development.

Repair Services

Return your registered product under warranty at no additional labor and parts cost. NI offers fault location, diagnostics, and repair any time the system fails as well as any adjustments needed to restore the hardware to manufacturing specifications.
