Seven new C Series modules provide strain accuracy, increased channel density and isolation.
National Instruments recently announced a new, high-speed H-bridge servo drive module and seven C Series modules for the National Instruments CompactRIO embedded platform. The new NI 9505 drive module for NI CompactRIO offers direct connectivity to actuators, such as fractional horsepower brushed DC servo motors, relays, lamps, solenoids and valves. With the addition of the new C Series modules, engineers now have more than 30 plug-in C Series modules to choose from and can connect to any industrial or automotive sensor or signal type.
With the low-power consumption and small size of the NI 9505 module, coupled with the reconfigurability and performance of the field-programmable gate array (FPGA), engineers can create intelligent, energy-efficient control systems using the National Instruments LabVIEW graphical system design platform. The NI 9505 delivers continuous current of up to 8 A at 40°C (or 2 A at 70°C) with a peak current of 12 A at 30 V while achieving 98% power efficiency. This module benefits electronics engineers designing consumer appliances, industrial control engineers designing small- to medium-sized machines, and automotive engineers working on rapid prototyping applications.
Engineers can use NI LabVIEW with the energy-efficient, realtime embedded processor and high-performance FPGA of the CompactRIO embedded control and acquisition system to create powerful motion control applications. By customising FPGA logic, engineers can accurately control torque, velocity and position, and implement advanced control techniques such as the use of notch filters and gain scheduling. With the CompactRIO realtime embedded processor, they can implement functions such as supervisory control and trajectory generation for multi-axis coordination and accurate velocity/acceleration profiles for smooth movements.
In addition to the NI 9505 module, NI is releasing seven new plug-in C Series modules for CompactRIO that deliver more analog inputs per module; high-performance strain; current, fuel cell and RTD analog inputs; and channel-to-channel isolation for digital I/O. With the new NI 9205 32-channel analog input module and any 8-slot CompactRIO chassis, engineers can build a 256-channel reconfigurable, embedded logging system. The new NI 9237 provides high-performance measurements for strain gauge and loadcell measurements and delivers 24 bits of resolution and up to 50 kS/s simultaneous sampling rates for dynamic strain applications. All new C Series modules feature built-in isolation, ensuring the safety of users, protection of expensive equipment and noise immunity. For additional isolation, the NI 9422 module features channel-to-channel isolation, offering the highest level of safety for industrial and automotive applications.
These new modules include:
* NI 9203 8-channel ±20 mA, 200 kS/s, 16-bit analog input module.
* NI 9205 32-channel ±200 mV to ±10 V, 250 kS/s, 16-bit analog input module.
* NI 9206 16-channel ±200 mV to ±10 V, 250 kS/S, 16-bit fuel cell analog input module.
* NI 9217 4-channel 100 Ω RTD, 100 S/s, 24-bit analog input module.
* NI 9237 4-channel full/half-bridge, 50 kS/s/Ch, 24-bit simultaneous analog input module.
* NI 9422 8-channel 24 V, 100 µs, channel-to-channel isolated digital input module.
* NI 9477 32-channel 5 V to 60 V, 8 µs, sinking digital output module.
Engineers can customise the timing and synchronisation of all CompactRIO modules using the FPGA within CompactRIO and LabVIEW. These new modules, along with the entire family of CompactRIO modules, integrate seamlessly with LabVIEW. This platform combines LabVIEW programming with commercial off-the-shelf measurement and embedded hardware targets to help development teams design, prototype and deploy systems more quickly and reliably.
