Alternating Relays

Macromatic specific-purpose Triplexor relays are ready to go right out of the box. ATP Series is pre-programmed for various triplex and duplex pump control applications. Save panel space. Reduce labor. No programing.

Question: I want my two loads to come on one after the other, but then both loads to stay on together until the last control switch is opened.

Issue: How do I make connections to my Alternating Relay? Solution/Resolution: Macromatic offers several versions of Duplex Alternating Relays.  The following examples are typically the way connections are made to the relays.  The loads could be pumps, compressors, or air conditioning/refrigeration units.

Issue: Do your Alternating Relays work on DC voltages? Your catalog used to only mention AC and the products were only marked as AC. 

Issue:

I have two float switches and two pumps in my application: a HIGH float switch to pump the water down and prevent an overflow of the tank, and a LOW float switch to turn the pump off and prevent the tank from being emptied & burning out the pump. 

Issue: How can I use one Switch to Cycle 3 loads ON & OFF in sequence? 

Issue: Can I use an Alternating Relay with one input voltage value to control multiple loads at a different voltage?

Issue: How do I prevent a Bouncing Control Switch Due to Splashing Water from Rapidly Energizing One Load and Then the Other?
