The 3730 PCI digital I/O interface provides 16 optically isolated inputs and 16 Reed relay outputs. The inputs protect the PC and other sensitive equipment from spikes and ground loop current that can be generated in industrial environments, while the outputs provide high quality, long-life, low current (10 Watt maximum), dry contact switch closures. Reed relays are well suited for low current applications. The relays are normally open, and close when energized.

Includes 3730 PC/104 board, ribbon cables, and Portholes™ mounting plate with removable screw terminals for installation in an enclosure.

Note: This item has a minimum order quantity (MOQ) of 25 units. Please contact your sales representative with any questions.
