LOGIC Component Technology
  • Nine functional electronic components
  • Mix-and-match inside of VIVISUN® switches and NEXSYS® LOGIC Modules for over 1,000,000 configuration options.
  • Designed and Tested to DO-160

The Challenges of System-to-System Integrations

Traditional methods for modifying the electronic systems of modern aircraft are often expensive and time consuming. Using custom printed circuit boards or a discrete single-function piece of hardware to add capabilities to these complex systems can bring challenges to the integrator as they face safety, software testing and certification issues. NEXSYS LOGIC Component Technology, from Applied Avionics, provides military and commercial system design engineers an innovative and flexible alternative that is simple, cost effective and can be implemented with the speed of COTS deliverability.

NEXSYS® LOGIC Components

LOGIC Component Technology is a set of ruggedized electronic building blocks that can be mix-and-matched together to create tailored system integration solutions. Functional components including latching flip-flops, solid state relays, Boolean logic gates, voltage sensors, pulse/timers, electronic rotaries, diodes and terminal junctions can be combined to create over 1,000,000 possible configuration options in a small form factor enclosure offering unparalleled design flexibility. LOGIC components can be configured inside VIVISUN® lighted pushbutton switches, as well as inside NEXSYS LOGIC Modules. Switches and Modules, each configured with LOGIC components, can be used together to create advanced solutions.

LOGIC Component Technology can be used to provide additional system features or provide quick solutions to unexpected changes or issues that can occur in the installation phase of a project. Additional features/benefits include:

  • Quick and easy certification due to complete RTCA DO-160 and MIL-STD testing on LOGIC components that contain no software or firmware.
  • Low power LOGIC components have virtually no load on aircraft power systems or standby battery and are compatible with existing aircraft system voltage levels.
  • Replace traditional, cumbersome, heavy or unreliable relay logic and time delays with compact, light-weight, solid-state alternatives.
  • Sophisticated functionality can be achieved by interfacing multiple modular LOGIC components together.
  • Address system interface problems, such as, changing a momentary signal to latched, adding time delays, signal buffering, polarity inversion, voltage sensing or establishing the enable/disable operation to occur only when a defined set of conditions exists.

What Electrical System Design Engineers are Saying

The following are Applied Avionics’ customer testimonials about their use of NEXSYS LOGIC Component Technology.

The benefits of using LOGIC Component Technology is the flexibility for a design engineer to implement an infinite number of complex control circuits in a fraction of the size of standard military grade products. I was able to use LOGIC Component Technology to create products for my customers that exceeded their expectations, while saving space, weight, time and money and increasing reliability.

Abel Z., Electrical Engineering Manager

I was able to solve a problem that arose late in the testing phase using LOGIC Component Technology. The robust, lightweight and configurable design allowed for a design change that was quickly implemented and with minimal impacts to the aircraft or schedule.

Paul R., Electrical Systems DER

LOGIC Component Technology provides simple and robust solutions to my designs because they allow the flexibility to incorporate multiple functions in a compact solution, thus reducing the number of external components that are normally required for designing multifunctional circuits.

Zac F., Electrical Systems Engineer

The biggest advantage to using LOGIC Component Technology is the reduction of bill of materials and less production time during terminations.

Jim K., Avionics/Electrical Engineer

LOGIC Component Technology has dramatically reduced my development time and costs. I've been able to eliminate custom electronic assemblies and the associated DO-160 environmental testing. My engineering effort has been reduced from man-months to a few man-days on most projects. The ability to go from conceptual design to an installed, fully tested and robust solution with a DO-160 pedigree in just a few weeks has completely changed the way we approach our custom aircraft integration projects.
