The Macromatic ATP024A7R is an alternating relay. This 12 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 balanced and more capacity is needed. It has an output of 3A SPNO, and works with 3 switch inputs (LEAD, LAG, LAG2). It can be used as a duplexor or a triplexor if three loads are present. Operation is chosen by selector switch. The selector switch can also lock the relay into a certain load, with that load energizing first. It uses a 12 pin SD12-PC square socket.
Note: 8 Pin plug in shown. Refer to drawings.

The ATP024A7R features 3 LED indicators that show which load energizes first. All three LEDs will blink in the event of an out-of-sequence switch. If power fails and comes back with more than the LEAD switch closed, a 10 second delay between energizing the loads will prevent all three from coming back at once.
