    This limit value switch is used in switch cabinets for process monitoring or for simple process regulation.
    Both temperatures and derived variables such as voltage, current and resistance are used as control signals. In the process, 1 or 2 limit values can be monitored.

    The universal configurability of the measuring inputs reduces the stock requirement for various applications.

    The housing widh of only 12.5mm enables space-saving installation in the switch cabinet. The scales for the limit value setting, illuminated red or green depending on the switch status, also enable operatingin dark environments. 

    For the assignment of the measuring unit to the scale labelling, 24 transparent adhesive labels are supplied. They can be fixed between the adjusting wheels on the front panel.
