The invention relates to a safety device for an industrial boiler (CHA) comprising relays (RE¿n?) which are connected to form an electromechanical safety chain (CH1). According to the invention, each relay (RE¿n?) is mounted on a printed circuit board (CI¿A?, CI¿B?, CI¿C?, CIP). As a result of said 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.
Le dispositif de sécurité pour chaudière industrielle (CHA) comprend des relais (REn) connectés pour former une chaîne de sécurité électromécanique (CH1).Dans ce dispositif, chaque relais (REn) est monté sur une carte de circuit imprimé (CIA, CIB, CIC, CIP). Avec cet agencement, les relais peuvent être montés dans un boîtier compact éventuellement scellé pour qu'il soit impossible à un opérateur d'exploitation d'accéder à un relais pour le bloquer.
