The Macromatic ATP024A1 is an alternating relay. This 8 Pin plug-in relay has a control voltage of 24V AC/DC. It is a triplexor relay used in situations where the run time of three loads needs to be equalized and 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, there is not a duplexor option. It uses an 8 pin 70169-D octal socket. Note: Image is an approximation. Actual part may differ.

The ATP024A1 features 3 LED indicators that show which load energizes first. All three LEDs will blink in the event of a switch failure. If power fails 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.
