The Macromatic TD-70528 is an Interval On 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 indicator displays the status of the timing mode and time out conditions. The TD70528 uses an 8 pin 70169-D octal socket. Note: Image is an approximation. Actual part may differ.
