Mechanical design The universal controller consists of terminal base and controller insert with built-in operation. The terminal base can be fitted to a DIN mounting rail or is screwed directly on a flat surface. It consists of a plastic housing with 2 terminal levels. The controller insert engages in the terminal base. It consists of a plastic housing which accommodates the printed circuit boards. Controller operation is fully integrated.
