The Macromatic TD-80521-42 is an Interval On Time Delay Relay. This programmable plug-in relay has an input voltage of 240V AC at 50/60Hz and 10A DPDT output contacts. The timing ranges are digitally selected by 10 position binary DIP switch, from 10 to 10230 seconds. The TD8052142 uses an 8 pin 70169-D octal socket. It features an LED indicator to show the current status of the relay. It shows green when the power is on, and red once the relay is energized. Note: Image is for reference, actual part may differ

The Interval On function means that the time delay starts along with the input voltage, energizing the relay. When the time delay stops it is de-energized. In order for the time delay to be reset, the input voltage needs to be taken out. Each DIP switch is labeled with a time increment. Move the necessary switches to the ON position and add up their labeled values to set the time delay. For example, to set the time delay for 1800 seconds (30 minutes), the switches for 40, 160, 320, & 1280 would be moved to the ON position.
