National Instruments PCI-7342

The National Instruments PCI-7342 is a sophisticated 2-axis motion controller designed for precise control of servo and stepper motors. Equipped with a real-time embedded operating system and advanced multiaxis interpolation capabilities, this controller facilitates fully coordinated linear, circular, and gearing motions, along with efficient contouring for complex trajectories. The PCI-7342 operates multiple motion control programs simultaneously with event-oriented multitasking, ensuring optimal performance without any external interruptions. It features a PID update rate ranging from 62.5 to 500 µs/sample and supports a maximum step frequency of 4 MHz, alongside an encoder input rate of 20 MHz. The device includes 32 digital I/O channels—accessible through a dedicated 68-pin connector—allowing programmable polarity and direction, with each output circuit capable of sourcing or sinking up to 24 mA. Additionally, it provides two PWM outputs for generating periodic waveforms at 32 kHz. Synchronization with other PCI-based devices is easily achieved through the RTSI connector, supporting up to eight RTSI trigger lines as either inputs or outputs. The PCI-7342 operates with the NI-Motion driver software and is built in a robust form factor measuring 6.9 x 3.9 inches and weighing approximately 170 grams. Power consumption is rated at 5.7 watts in standard operation. Though designated for end-of-life status by National Instruments, the PCI-7342 remains available for purchase and repair through Apex Waves. Each unit is backed by a three-year warranty and supported by comprehensive user and maintenance manuals available for download. For pricing inquiries, please contact a sales representative.
