Overview
The NI 9219 is a four-channel universal C Series module designed for multipurpose testing in any NI CompactDAQ or CompactRIO chassis. With the NI 9219, you can measure
several signals from sensors such as strain gages, RTDs, thermocouples, load cells, and other powered sensors. The channels are individually selectable, so you can perform a
different measurement type on each of the four channels. Measurement ranges differ for each type of measurement and include up to ±60 V for voltage and ±25 mA for current.
Please see the manual for detailed specifications and ranges.

Application and Technology
Because of the driver design, the NI 9219 does not limit the overall speed of an NI CompactDAQ system when used with faster sampling modules. With 250 Vrms of
channel-to-channel isolation, the NI 9219 protects not only the surrounding modules, chassis, and connected computer system but also the other channels within the same
module. In addition to increased safety, channel-to-channel isolation eliminates problems associated with ground loops.
Connectivity Accessories
The NI 9219 uses six-position spring terminal connectors in each channel for direct signal connectivity. You can purchase additional connectors to reduce signal connection time
for multiple test units. In addition to extra connectors, a strain relief kit is available to secure the signal wires. NI recommends:
NI 9972 - strain relief backshells for signal wire security and high-voltage protection (qty 4)
NI 9973 - extra connectors for six-position connector modules (qty 10)
NI C Series Compatibility
The NI C Series hardware family features more than 50 measurement modules and several chassis and carriers for deployment. With this variety of modules, you can mix and
match measurements such as temperature, acceleration, flow, pressure, strain, acoustic, voltage, current, digital, and more to create a custom system. Install the modules in one
of several carriers to create a single module USB, Ethernet, or Wi-Fi system, or combine them in chassis such as NI CompactDAQ and CompactRIO to create a
mixed-measurement system with synchronized measurements. You can install up to eight modules in a simple, complete NI CompactDAQ USB data acquisition system to
synchronize all of the analog output, analog input, and digital I/O from the modules. For a system without a PC, CompactRIO holds up to eight modules and features a built-in
processor, RAM, and storage for an embedded data logger or control unit. For higher-speed control, CompactRIO chassis incorporate a field-programmable gate array (FPGA)
that you can program with NI LabVIEW software to achieve silicon-speed processing on I/O data from C Series modules.
Advanced Features
When used with CompactRIO, NI C Series analog input modules connect directly to reconfigurable I/O (RIO) FPGA hardware to create high-performance embedded systems. The
reconfigurable FPGA hardware within CompactRIO provides a variety of options for custom timing, triggering, synchronization, filtering, signal processing, and high-speed
decision making for all C Series analog modules. For instance, with CompactRIO, you can implement custom triggering for any analog sensor type on a per-channel basis using
the flexibility and performance of the FPGA and the numerous arithmetic and comparison function blocks built into the LabVIEW FPGA Module.
Key Features
High-accuracy, high-performance analog measurements for any CompactRIO embedded system, R Series expansion chassis, or NI CompactDAQ chassis
Screw terminals, BNC, D-Sub, spring terminals, strain relief, high voltage, cable, solder cup backshell, and other connectivity options
Available channel-to-earth ground double-isolation barrier for safety, noise immunity, and high common-mode voltage range
CompactRIO Extreme Industrial Certifications and Ratings
Built-in signal conditioning for direct connection to sensors and industrial devices

Support and Services
System Assurance Programs
NI system assurance programs are designed to make it even easier for you to own an NI system. These programs include configuration and deployment services for your NI PXI,
CompactRIO, or Compact FieldPoint system. The NI Basic System Assurance Program provides a simple integration test and ensures that your system is delivered completely
assembled in one box. When you configure your system with the NI Standard System Assurance Program, you can select from available NI system driver sets and application
development environments to create customized, reorderable software configurations. Your system arrives fully assembled and tested in one box with your software preinstalled.
When you order your system with the standard program, you also receive system-specific documentation including a bill of materials, an integration test report, a recommended
maintenance plan, and frequently asked question documents. Finally, the standard program reduces the total cost of owning an NI system by providing three years of warranty
coverage and calibration service. Use the online product advisors at ni.com/advisor to find a system assurance program to meet your needs.
Calibration
NI measurement hardware is calibrated to ensure measurement accuracy and verify that the device meets its published specifications. To ensure the ongoing accuracy of your
