The 26NO240 is a time delay relay device from Amperite, a manufacturer of relays, switches, timers, and other electrical control devices. It is a single-pole, double-throw, time-delay relay that contains a power transformer and coil. The 26NO240 provides an output when triggered by an electrical input. Its internal timing circuit ensures that the output remains on for a preset period of time – from five seconds up to 10 minutes – after the input signal is complete. The delay time can be adjusted by using potentiometers on the device. The 26NO240 also has LED indicators to provide visual feedback regarding the state of the delay circuit. The device is designed for use in industrial, commercial, and home applications.
