Alerton's expansion modules (EXP) , are part of the VLX Global controller (VLX) inwhich we can connect up to 8 expansion modules in any combination to create a complete package for a variety of applications.

Digital outputs have indicatorLED  and also  all    outputs have HAND-0-AUTO switch and potensiometer for the analog outputs, making testing and comissining more easier.

Available models:

EXP-2200  Module with 22 universal inputs

EXP-1048  Module with 10 universal inputs, 4 digital triac outputs, and 8 analog outputs.

EXP-10120  Module with 10 universal inputs, andι 12 digital triac outputs.

By combining the above models we can cover almost any control poin application.
