National Instruments NI-9265 C Series Current Output Module

The National Instruments NI-9265 (Part Numbers: 783733-01, 779334-01, 779334-02) is a 4-Channel, 16-Bit, 0 mA to 20 mA range Current Output Module. This model offers 100 kS/s per channel, simultaneous analog output on all four channels and is compatible with any CompactRIO or CompactDAQ chassis. The NI-9265 is a suitable choice for interfacing and modulating or controlling industrial grade, current-driven actuators at high-rates. This device comes with integrated open-loop detection, which generates a software interrupt whenever an open loop is detected. Moreover, to ensure safety and avoid actuators activity at system power-on, the NI-9265 restricts outputs.

 For better noise immunity performance, the NI 9265 module includes a channel-to-earth ground barrier as well. Each channel has a 16-bit, String type Digital-to-Analog Converter (DAC) that generates a current signal. This Current Output Module is designed to offer up to 600 Ω load, maximum. With this module, users can utilize a 9 VDC to 36 VDC external power supply. The National Instruments NI-9265 features protection against overvoltage and short-circuit on its channels. In its default configuration, the overvoltage protection setting is ±40 V.  

While operating with four channels, this Current Output Module can operate with 12 μs update rate in an R Series Expansion Chassis and 9.5 μs when used in any other chassis. The NI-9265 is available in three variations, based on the type of connection. It is available with non-conformal coated Screw Terminals (Part Number: 779334-01), Spring Terminals (Part Number: 783733-01), and Conformal Coated Screw Terminals (Part Number: 783733-01). The conformal coated version is an ideal solution for applications in a moisture rich environment.  

The NI-9265 is run using the NIDAQmx driver software which is compatible with software packages/application development environments (ADEs) like LabVIEW, LabWindows/CVI, or ANSI C.

The NI device weighs 4.8 oz. It has a recommended operating temperature range of -40 °C to 70 °C, a storage temperature range of -40 °C to 85 °C, an operating and storage humidity range of 10% RH to 90% RH and 5% RH to 95% RH, and a random and sinusoidal operating vibration of 5 grms and 5 g respectively–all at a frequency range of 10 to 500 Hz.

The NI-9265 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the NI-9265 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the NI-9265 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped.
