Abstract (en)
[origin: US7385316B2] A safety device for an industrial boiler (CHA) including relays (RE<SUB>n</SUB>) which are connected to form an electromechanical safety chain (CH 1 ). Each relay (RE<SUB>n</SUB>) is mounted on a printed circuit board (CI<SUB>A</SUB>, CI<SUB>B</SUB>, CI<SUB>C</SUB>, CIP). As a result of the arrangement, the relays can be mounted in a compact box that may be sealed so that it is impossible for an operator to access a relay in order to block it.
