The Macromatic TD-78122 is an 11 Pin Time Delay Relay. This digital set programmable plug-in relay has an input voltage of 120V AC/DC. It is a multi-function unit with 10 different settings and a time range of 0.05 sec to 999 hours. The unit features pushbutton thumbwheels that set a more precise time delay and one of seven time ranges. A separate thumbwheel can choose the function and the red LED shows the status of the timing mode. The TD78122 uses an 11 pin 70170-D octal socket with an output of 10A DPDT.
