NEXSYS® Module

NEXSYS® Module
  • Ruggedized, Small Form-Factor Enclosure for NEXSYS Components
  • Fourteen functional electronic components, each with optionality provides over 1,000,000 component configuration options
  • Includes an Inline Harness Boot or can be bracket or Type-I rail mounted
  • NEXSYS Components are designed and tested to DO-160 standards

The NEXSYS® Module is a ruggedized, small form-factor enclosure that allows avionics system designers to create custom behind-the-panel avionic solutions that meet their exact functional requirements. The NEXSYS Module is ideal for many applications such as communications systems, computer/logic level interface to electro-mechanical systems, fire suppression systems and IFE systems.

NEXSYS Modules can replace the expense and certification delays that are typically encountered when creating a circuit board to solve design challenges. With three different mounting options, NEXSYS Modules deliver a powerful combination of configurable electronic components in a single robust package designed and tested in accordance with DO-160.

The NEXSYS Module can be used as stand-alone devices for system-to-system interface or can be combined with man-machine interface devices such as lighted pushbutton switches.

NEXSYS Component Options

The NEXSYS Module can accommodate a wide range of components with specific electronic functionality such as electronic flip-flops, solid state relays, diodes, and other more complex devices. Each NEXSYS component is either a Series A (4-pin) device, Series C (8-pin) device, Series N (8-pin) device or Series R (12-pin) device.

NEXSYS Module Configurations

A NEXSYS Module has four available, 4-pin positions (H, J, K and L in the diagram). Any Series A (4-pin) NEXSYS component can occupy one of the available four positions.

NEXSYS Modules can accommodate one or two Series C, 8-pin NEXSYS components. Each Series C component will occupy two of the available positions. When one Series C, 8-pin component is used, it will occupy the two middle positions (J and K), leaving two available 4-pin positions. When two Series C, 8-pin components are used they will be configured side-by-side leaving no available positions.

The ARINC 429 Converter is either a Series N device or a Series R device depending on the specific configuration options chosen. The form factor of a Series N (8-pin) component is larger than the Series C (8-pin) component. Because of this, a NEXSYS Module with an ARINC 429 Converter component will have no other positions available for additional NEXSYS components.

Unoccupied positions will be configured with an Open spacer. NEXSYS Modules require the use of Connector Plug (P/N 18-440).

Up to four NEXSYS components in a single NEXSYS Module

Installation & Mounting

NEXSYS Modules require the use of a keyed CTS Connector Plug (P/N 18-440). The Connector Plug can be inserted into the module before or after insertion into any of the mounting variations. The Connector Plug can be removed from the module using an Extraction Tool (P/N 18-234) without removing the module from the mounting. NEXSYS Modules can be mounted in one of the following three ways:

In-line Harness Boot: Module should be encased in the boot provided and secured to the harness using industry standard methods for in-line harness wiring.

Flush Mount Bracket: Enclose module in bracket and mount bracket using customer provided fasteners. Removal of the module requires unfastening of the mounting bracket. Bracket hole spacing is consistent with many standard relay mountings.

Right Angle Bracket: Bracket can be mounted (using customer provided fasteners) with or without module inserted. Slide module into bracket and ensure module has positively “clicked” into bracket. The module can be removed from the bracket (without removal of the bracket from the mounting surface) by releasing side retaining clips. Bracket hole spacing is consistent with many standard relay mountings.

Type 1 Rail: Slide the module into the rail and secure using the lock-down bar that accompanies the rail. The module can be removed from the rail by releasing the lock-down bar and sliding the module out.

NEXSYS Modules will come supplied with an in-line Harness Boot. The optional brackets and Type 1 rail may be ordered separately on our Part Configurator.
