If you wish to add an electromagnetic relay to switch off/switch on any external electric load, just use this output to drive the electro-magnetic relay with the help of a suitable transistor-based ...

The TRS-TD series off-delay timer relay replaces the functionality of bulky, costly, and inaccurate pneumatic time-delay relays and does not require a trigger switch or application of continuous input ...

Analog circuits such as the "brute force" resistor-capacitor solution ... This forces the output high for approximately 100 ms, which is plenty of time for most relays or solenoids to latch fully.

This power-conditioning circuit for an automotive electronic control unit replaces bulky transient absorbers with an electronic switch, Q1, and an electromechanical relay with an RC timer circuit ...

The digital timer relay features a LED display, an on-delay timer, and a time setting range from 0.01 to 990 hours, with various supply voltages such as 12V DC, 24V DC, 24V AC, 220V AC, 240V AC ...
