た信号装置。 A coil of a relay connected to a power supply through an external contact, a load connection terminal connected to the power supply through the contact of the relay, and a current inserted in series in a load power supply path from the power supply to the load connection terminal. a series circuit of a fuse and a current-limiting impedance, and the current-limiting impedance is configured to prevent the contacts of the relay from welding before the current fuse is blown by the current flowing in the load power supply path when the load connection terminal is short-circuited. A signal device with a resistance value set.
