The Macromatic ATP120A1 is an alternating relay. This 8 Pin plug-in relay has a control voltage of 120V AC. It is a triplexor relay used in situations where the run time of three loads has to be equalized and where more capacity is needed. It has an output of 3A SPNO, and works with 3 switch inputs (LEAD, LAG, LAG2). It is used solely as a triplexor switch, it will not operate as a dual load switch. It uses an 8 pin 70169-D octal socket.

The ATP120A1 has 3 LEDs that indicate which load energizes first. All three LEDs will blink in the event of a switch failure. If the power goes out and comes back with more than the LEAD switch closed, a 10 second delay between energizing the first load and the other loads will prevent all three from coming back at once.
