Macromatic Alternator Relay
120 Vac 10 A DPDT x Wired
Description of Function In the off state, both the LEAD Switch and the LAG Switch are open, the Alternating Relay is in the LOAD 1 position, and both LOAD 1 & LOAD 2 are off. The red LED marked “LOAD 1” is ON. When the LEAD Switch closes, it energizes LOAD 1. As long as the LEAD Switch remains closed, LOAD 1 remains energized. If the LAG Switch closes, it energizes LOAD 2. When the LAG Switch opens, LOAD 2 is turned off. When the LEAD Switch opens, LOAD 1 is turned off and the Alternating Relay toggles to the LOAD 2 position. The red LED marked “LOAD 2” is ON. When the LEAD Switch closes, it turns on LOAD 2. If the LAG Switch closes, it will energize LOAD 1. When the LAG Switch opens, LOAD 1 is turned off. When the LEAD Switch opens, LOAD 2 is turned off, the Alternating Relay toggles back to the LOAD 1 position, the red LED marked “LOAD 1” is ON, and the process can be repeated. NOTE: the LEAD switch must always close before the LAG switch and must always open after the LAG switch. Product Overview Features: For Duplex Control of two loads Control Voltages of 12 & 24V AC/DC and 120 & 240V AC Three 10A output contact configurations: SPDT, DPDT, or DPDT Cross-Wired Optional low profile selector switch to lock in one sequence 2 LEDs indicate relay status Configuration / Contact Rating: 10A @ 240V AC/24V DC, 1/2HP @ 120/240V AC (N.O.), 1/3HP @ 120/240V AC (N.C.) 10A @ 240V AC/24V DC, 1/2HP @ 120/240V AC (N.O.), 1/3HP @ 120/240V AC (N.C.)

The Red LED marked “LOAD 1” is On. When the LEAD Switch closes, it energizes LOAD 1. As long as the LEAD Switch remains closed, LOAD 1 remains energized. If the LAD Switch closes, it energizes LOAD 2. When the LAG Switch opens, LOAD 2 is turned Off. When the LEAD Switch opens, Load 1 is turned OFF and Alternating Relay toggles to the LOAD 2 position.
