Product Details

• Duplex alternating relays are used in control panels where two loads are required to alternate to provide equal pump run times
• The alternating action is initiated by a control switch, which is common with one side of the control voltage
• The output contacts will change states each time the control switch is opened, thus alternating the two loads
• LED indicators show the position of the output relay
• The ARB has the automatic alternating feature plus the option of locking it into one mode
• The ARA series is the standard Duplexer providing automatic alternating sequence
• Control Voltage: 120 VAC/DC, ±10%
