ATP120A7R
Use Socket: SD12-PC
May not be exact product—for reference only.
- Family: ALTERNATING RELAY
- Function: TRIPLEXOR w/ SWITCH FOR TRIPLEX/DUPLEX OPERATION
- Control Voltage: 120V AC
- Output: (3) 3A SPNO
Description Of Function
All three switches are open and all loads are off. 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, Load 2 is energized. If the LAG2 Switch closes, it energizes Load 3. Each load is turned off in sequence as the switches are opened. The entire cycle is then repeated, but with Load 2 energized first followed by Load 3 and then Load 1. NOTE: power for outputs is supplied from L connection, not through input switches (see drawing below).

Application Information
- Voltage Tolerance: AC Operation: +10/-15% of nominal at 50/60 Hz.; DC Operation (24V only): +10/-15% of nominal.
- Load (Burden): 2 VA
- Indicator LEDs: One of the Red LEDs will be steady ON to indicate which Load will be energized first; all will flash to indicate a switch out-of-sequence error.
- Time Delay: If power is lost & returns with more than just the LEAD Switch closed, there is a fixed 10 second delay between energization of the second output (Triplex & Duplex mode) & third output (Triplex mode only) to prevent all Loads from coming on at the same time.
- Output Contacts: 3A @ 24V AC General Purpose; C300 Pilot Duty; 1/6HP @ 24VAC
- Life: Mechanical: 10,000,000 operations; Full Load: 100,000 operations
- Temperature: -28o to 65o C (-18o to 149o F)
