蔵形緩放リレー。 A slow release relay configured such that the relay contact drops after a predetermined period of time has passed after the input voltage is cut off, has two terminals, an external power connection terminal and a ground connection terminal, while the voltage is applied via the external power connection terminal. A timer section that makes the output zero after a predetermined period of time has passed after the input voltage is cut off, a signal input line connected to the output side of the timer section, and a power supply line connected to the external power connection terminal, and the A relay drive unit that de-energizes the relay excitation coil to drop the relay contact when the output of the timer unit becomes zero, and a relay drive unit that is parallel to the relay drive unit between the external power supply connection terminal and the ground connection terminal. A connected internal power supply, a diode whose anode is connected to the external power supply connection terminal side and a cathode connected to the positive terminal side of the internal power supply, and an internal power supply voltage is applied to the input side of the timer section when the diode is short-circuited. A slow release relay with a built-in power supply, comprising a means for preventing voltage from being applied.
