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.
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.
