Description
A limit switch DNOVA APL-410N EX is an electrical device designed to open and close a working circuit and to visualize the positions of the shut–off valve of a pipeline valve. In a sealed box, as a rule, there are two mechanical switches designed for voltages up to 250 V, which monitor the position of the drive rod and signal in extreme positions. They are mounted on top of the surface of the drive. A two-color hemisphere of a visual indicator is located in the upper part of the limit switch block. If the connected pipe fittings are closed, then only the red part of the hemisphere with the inscription CLOSED is visible; if open, only the yellow part with the inscription OPEN. This visual indicator is clearly visible from afar, which simplifies the inspection of equipment, and the color difference between the open and closed positions reduces the likelihood of erroneous perception of information. Thanks to the use of LSU, it becomes possible to transmit information about the position of the pipeline.
