Finding I/O modules to integrate into your real-time, mission-critical systems can be difficult as each application has its own requirements. You need fast and reliable movement of information between the various elements in your interconnected system and external sensors.

Your programs are long-term, and you need assured long-term availability to keep them in top shape for years, if not decades.

COTS provides the flexibility and fast availability of solutions, and when something needs a twist, Modified COTS (MCOTS) provides new options. With our extensive experience in the production of COTS signal acquisition hardware, we designed our I/O and communications solutions to handle the toughest operating environments.

Our sensor I/O product family includes rugged, high performance solutions to support intelligent analog I/O to over 20 Gsps, multi-channel fiber-optics and customizable, multi-standard digital IO. These modules deliver optimal performance in rugged formats to the extremes of temperature and vibration conditions, are designed to easily integrate with other elements of our product line, and are supported by our lifecycle services to keep your systems delivering for the long haul.

We offer open standard compliant PMC, XMC, 3U VPX, 6U VPX, FMC and 6U VME cards designed to popular communications standards such as ARINC, StarFabric, MIL-STD-1553, Ethernet, CANBus, and Fibre Channel.
