The NI 9265 is a 4-channel, 16-bit analog output module engineered for high-resolution current generation in industrial control applications. It generates 0 mA to 20 mA output signals with simultaneous channel updates at 100 kS/s per channel, making it ideal for precision actuator control and process automation. The module features screw terminal connectivity rated for 0.5 N·m to 0.6 N·m torque, built-in open-loop detection with software interrupt capability, and automatic output zeroing on power-on for enhanced safety.
