Preo Strain Driver 121 digital controller

STRAIN DRIVER
The STRAIN DRIVER 121 digital control unit runs up to 6 hot melt guns fully independently, for all functions and allows repeatability that far outstrips normal applications, thanks to its innovative electronics.

CONNECTIONS
Quick coupling connectors on the back of the unit are used to connect all the Input and/or Output signals and the photocells required for the system to operate properly.

GRAPHIC DISPLAY
An LCD provides a graphic display of the sections and the parameters that can be set for programming the guns. The graphic icons are easy to interpret, even by nonspecialist personnel, eliminating problems generated by codes and foreign languages independently of the country of use.

PROGRAMMING SELECTOR
Another innovative feature is the programming method of all the operating parameters that is carried out through a single control consisting of a selector with built-in button. Every time the knob is pressed, another parameter appears, which is increased or decreased by turning the knob clockwise or anti-clockwise direction.

LIGHT INDICATORS
4 leds show the system status and any alarms or faults that arise while the unit is operating.
