Last Revised: 2012-11-20 03:53:17.0 16-Channel Current Input Module NI 9208 16 current inputs (±21.5 mA) -40 to 70 °C High-resolution mode with 50/60 Hz rejection 60 VDC, CAT I bank isolation (1,000 Vrms withstand) 500 S/s sample rate (high-speed mode) Optional NI 9933 connectivity kit shown in image on right Voltage supply pins for external power routing (2 A/30 V maximum) 24-bit resolution Overview The NI 9208 current input C Series module has 16 channels of ±21 mA input with built-in 50/60 Hz rejection for noise rejection. Designed with industrial systems in mind, the NI 9208 has a high-channel density to reduce the number of modules you need. This opens slots for other measurement types and reduces the overall cost per channel of the system. The NI 9208 has a standard 37-pin D-Sub connection for use with available cables and connector blocks, or the NI 9937 D-Sub connector kit. The NI 9937 contains a D-Sub to screw terminal accessory as well as a protective shell. With this kit, you can create a custom cable that plugs directly into the module, eliminating the need for a separate terminal block.

This style of filter attenuates the most common noise in an industrial environment that is caused by lighting, motors, and power lines. Channel Density for High-Channel-Count Systems Process and control applications can require a large number of sensor inputs. With the NI 9208, you can connect up to 16 pressure, load, torque, or other transducers to a single module. Install multiple modules in a single system for up to 128 channels of 4 to 20 mA inputs. Voltage Supply Pins for Easier Wire Routing The NI 9208 has multiple voltage supply (Vsup) pins so you can wire a single power supply into the module and then route the power to the individual sensors through the module I/O pins. The NI 9208 can support up to 2 A of current and up to 30 VDC. Industrial Ratings for Rugged and Reliable Operation C Series modules have industrial certifications and ratings for operation in harsh environments. Modules are rated for a -40 to 70 °C (-40 to 158 °F) temperature range, 50 g shock, and hazardous locations or potentially explosive environments (Class I, Division 2). The NI 9208 features 60 VDC, CAT I isolation and up to 1,000 Vrms transient withstand. Each module comes with a variety of international safety, electromagnetic compatibility (EMC), and environmental certifications and ratings. For more specific information on the industrial certifications and other specifications, refer to the operating instructions manual. Note: Not all C Series systems conform to the maximum specifications of the individual modules. Consult the specifications section of the manual for the specific chassis or carrier to determine the maximum operational environment. C Series Compatibility The 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. See the C Series Compatibility Chart for information on supported modules and carriers. Back to Top Ordering Information For a complete list of accessories, visit the product page on ni.com.

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.
