The Macromatic ARP120A2R is an alternating relay. This 11 Pin plug-in relay has a control voltage of 120V AC. It is a DPDT duplexor relay used in situations in which the run time of two loads has to be equalized. It has an output of 10A DPDT. A control switch starts the alternating action. The output contacts on the relay change state when the initiating switch opens, so the loads alternate. It uses an 11 pin 70170-D octal socket. Note: Image is an approximation. Actual part may differ.

The ARP120A2R has 2 LEDs that indicate which load energizes next. The unit also has a low profile selector switch to lock into one load, so only one load remains energized. This is beneficial if one load has been used more than the other, so the on-time can be balanced.
