Description
High-Speed DAQ with Advanced Triggering: The DM35838HR is a high-speed digital I/O data module in a PCIe/104 format providing Opto-Isolated Digital Inputs and Outputs to interface with a variety of devices. The Inputs allow for a broad range of input voltages, and are compatible with 5V, 12V, and 24V systems. The high-current Outputs allow for driving LEDs, relays, and solenoids. This module includes many features such as pulse width modulators (PWM), incremental encoders, and advanced interrupts. The PCIe interface provides compatibility with the latest generation of CPUs, and the PCIe lane repopulation allows for virtually limitless system expansion.
