| Datasheet | Download Datasheet |
The Macromatic ATP024A7R is an alternating relay with 3A 3PST-NO output and rated 3 A at 24/120 V AC general purpose, driven by a 24V AC/DC input.
It rotates three loads so each takes its turn leading, and can be set to run as a two-load duplexor until a third load is added.
It is driven by a LEAD, a LAG and a LAG2 switch, closed and opened in sequence; a switch closing out of sequence is detected and flagged.
It plugs into a 12 Pin Square socket.
The selector switch is rotary: Triplex or Duplex, and optionally lock LOAD 1, 2 or 3 to energise first.
After a loss of power it staggers its outputs by 10 seconds, so the loads do not all restart at once.
It has Socketable mounting and Plug In terminals.
