The first emergency stop module, by DOLD developed in 1988, was called BN 5983 for man-machine protection. Conventional contactor controls have high cost interconnection wiring, but instead of that you can use this product and save a lot of money as well as space in control cabinet. This new module is revolutionary as it is only 17.5 mm wide and 70 mm deep.
DOLD offers specific emergency stop button monitor as well as bus outputs for in big installations with various emergency stop buttons it is necessary to know quickly which emergency stop button has been operated to save time .
