Key Features


The DM35956HR combines 16 power relay outputs and 16 Opto-Isolated Digital Inputs on one board. The relays may be used to reliably switch voltages from 5VDC up to 250VAC. Both Normally Open (NO) and Normally Closed (NC) contacts are available at the I/O connectors. This board can be used in applications such as AC or DC power circuit breaking, motor and actuator control or voltage level shifting. The Inputs allow for a broad range of input voltages, and are compatible with 5V, 12V, and 24V systems. The PCIe interface provides compatibility with the latest generation of CPUs, and the PCIe lane repopulation allows for virtually limitless system expansion.
