The Macromatic TD-70228 is an On Delay Time Delay Relay. This 8 pin plug-in relay has an input voltage of 24V AC/DC with an output of 10A DPDT. It has a time range of 0.05 sec to 999 hours. The unit has one pushbutton thumbwheel that chooses one of seven time ranges, while three other thumbwheels digitally set the precise time delay within that range. The red LED shows the status of the timing mode and time out conditions. The TD70228 uses an 8 pin 70169-D octal socket.

With the On Delay function, the time delay starts when the input voltage is introduced. The relay energizes after the time delay. The relay de-energizes when the input voltage is taken out, which also resets the time delay. Pilot duty rating
