The device meets the requirements of EN 60947-5-1, EN 60204-1 and VDE 0113-1. The contact expansion block serves as an expansion device for contact reinforcement and contact duplication of the instantaneous safety contacts of a basic device. Basic devices are all safety switching devices with feedback circuit monitoring. The category to be implemented according to EN 954-1 and EN ISO 13849-1 depends on the category of the basic device. It cannot be exceeded by the contact expansion block. The device meets the following safety requirements: The contact expansion block expands an existing circuit. Since the output relays are monitored by the feedback circuit of the basic device, the safety functions of the existing circuit are transferred to the contact expansion block. The safety device remains effective even if a component fails. Ground fault in the feedback circuit: Is detected depending on the basic device used. Ground fault in the input circuit: The output relays drop out and the safety contacts open
