The Viking AR10BTC0470N is a low-voltage time-delay relay. It is designed to be triggered at any preset time setting, breaking or making a circuit at whatever preset time the user chooses. It features SPDT (Single Pole Dual Throw) contact configuration, and its maximum voltage rating is 250VAC. The relay also has dual adjustment screws, which can be set to 0.1-59 second or 1-60 minutes delay settings. It's an ideal component for controlling motors, pumps, fans, and other devices that may need to be turned on and off at a certain delay.
