Description

The ATC Diversified ARB series duplexers are used in control panel applications where two loads are required to alternate in order to provide equal run time. The alternating action is initiated by a control switch, which is common to one side of the control voltage. The output contacts will change states each time the control switch is opened, thus alternating the two loads. The LED indicators show the position of the output relay.

The ARB series has the automatic alternating sequencing feature plus the option of locking into a single sequence. A three position switch permits the field selection of normal duplexing action, locking in the A-B sequence, or B-A sequence, as required.

Features:

• For the equal alternating of two loads
• Wide range of available models
• 3-position switch-to-lock sequence
• 8-pin plug-in enclosure

Applications:

• Municipal water plants
• Wastewater treatment facilities
• Large aquarium pumps
• Water well installations
• Level and pumping control systems
• Industrial pump level monitoring
