National Instruments (NI) announced a new H-bridge servo drive module and seven C series modules for the 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. The C series modules are said to give engineers over 30 plug-in C series modules, and can connect to any industrial or automotive sensor or signal type.

The NI 9505 delivers continuous current of up to 8A at 40C (or 2A at 70C) with a peak current of 12A at 30V while achieving 98 percent 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, said the company.

NI also released seven new plug-in C series modules for CompactRIO that are said to offer 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 strain gage and load cell measurements, and delivers 24bits of resolution and up to 50KSps simultaneous sampling rates for dynamic strain applications. The modules feature built-in isolation, protection of 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, an 8-channel 20mA, 200KSps, 16bit analog input module; NI 9205, a 32-channel 200mV to 10V, 250KSps, 16bit analog input module; NI 9206, a 16-channel 200mV to 10V, 250KSps, 16bit fuel cell analog input module; NI 9217, a 4-channel 100 ohm RTD, 100Sps, 24bit analog input module; NI 9237, a 4-channel full/half-bridge, 50KSps/Ch, 24bit simultaneous analog input module; NI 9422, an 8-channel 24V, 100s, channel-to-channel isolated digital input module; and NI 9477, a 32-channel 5V to 60V, 8s, sinking digital output module.
