Description

The SL-1952 module allows almost any type of device to be integrated and interfaced with our SmartLink-III™ Cabin Management System. Its 32 discrete channels can be configured as inputs or outputs, making uses for this module virtually limitless. Need an external door switch to turn on a group of lights inside your aircraft cabin? Need a special projection screen to unroll from the ceiling when you select for a particular video source? This module will do it. Do you have multiple Master or VIP panels that need to control the same discrete functions? Normally, duplicate wire runs to each Master Panel would be required. With our system, just tie each discrete into the SL-1952 module and let the “fly-by-wire” logic of the SmartLink-III™ handle the rest. No matter what your special or custom interfacing need is, this module can handle it. The module itself is very lightweight and compact, and can be easily installed within the tight confines of today’s corporate aircraft interiors. Only a minimum number of cable hook-ups are required to connect the module into the SmartLink-III™ wire bus. The large number of channels available with this module means it will easily handle all your custom aircraft switching needs and offer room to grow.

Application

Virtually any piece of equipment that requires interfacing with our SmartLink-III™ cabin management system
