C Series Analog Output Modules

Overview

High-performance analog output modules for National Instruments

CompactRIO embedded systems, R Series expansion chassis, and

NI CompactDAQ provide accurate signal generations. Each module

features built-in signal conditioning and an integrated connector with

screw terminal or cable options for flexible and low-cost signal wiring.

All modules feature the NI CompactRIO Extreme Industrial Certifications

and Ratings.

System Compatibility

You can use NI C Series modules in multiple system types depending

on available software. Please see the table above for CompactRIO and

NI CompactDAQ module compatibility because not all modules work

with both systems. Many of the advanced features described apply

only to reconfigurable I/O systems and not to NI CompactDAQ.

Advanced Features

Advanced features include ±30 V overvoltage protection and short-circuit

protection, simultaneous 16-bit per-channel digital-to-analog converters

(DACs), high-speed settling, excellent monotonicity and NIST-traceable

calibration. The NI 926x modules include a channel-to-earth ground double-

isolation barrier for safety and noise immunity. The NI 9265 provides high-

performance, 0 to 20 mA analog outputs ideal for controlling industrial

pressure, flow, and position actuators. The NI 9265 requires a 9 to 36 V

external power supply for driving the output current of the module.

When used in CompactRIO, C Series analog output modules connect

directly to reconfigurable I/O (RIO) FPGA hardware to create high-

performance embedded systems hat deliver the optimization and

flexibility of a custom electrical circuit completely dedicated to your

input/output application. The reconfigurable FPGA hardware within

CompactRIO provides a variety of options for timing, triggering,

synchronization, change detection, digital pattern matching, or digital

communication. For instance, with CompactRIO you can implement a

circuit to generate complex arbitrary waveforms, perform filtering or

splining to generate a smooth output signal based on a choppy low-

speed output command, simulate a nonlinear sensor, or implement

amplitude/phase modulation.
