Description
Le TestScale permet la connexion de cinq modules d'E/S ou d'alimentation supplémentaires via USB, avec un emplacement réservé pour le module de base. Le fond de panier TestScale supporte les modules pris en charge, y compris les alimentations programmables et les modules d'E/S, via une connexion SUB-D standard de 37 broches et USB pour la communication avec les ordinateurs industriels.
