Pump Level and Controls

The Marsh Bellofram ATC Diversified Electronics division offers two unique motor protection products, designed to operate together to provide a cost-effective added safeguard for the monitoring and performance of industrial motors.

ARA, ARB Series Duplexer Alternating Relays

ARA ARB SeriesARA and ARB series duplexers from the ATC Diversified Electronics Division of Marsh Bellofram 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.

ARA Triplexor and Quad Alternating Relays

ARA Triplexor and Quad Alternating RelayARA series duplexers and quadraplexers from the ATC Diversified Electronics Division of Marsh Bellofram are designed for use in multiple load installations that are required to alternate in sequence while assuring equal run time on all loads. They also allow for additional loads to run in the event of excess load requirements, with the option of automatic or external clocking alterations.

ARA Series Expandable Alternating Relays

ARA Expandable Alternating RelayARA series expandable alternating relays from the ATC Diversified Electronics Division of Marsh Bellofram are designed for use in multiple load installations that are required to alternate in sequence and have the ability to accept an additional load installation in the future.

ARA-120-AHE Alternating Relay

ARA-120-AHEThe ARA-120-AHE special function triplexer alternating relays from the ATC Diversified Electronics Division of Marsh Bellofram are designed for use in three-load installations. This model has a field selection switch that is used to omit one of the three loads for general or emergency maintenance while depleting the remaining two loads

ARA-120-AJE Alternating Relay

ARA-120-AJEThe ARA-120-AJE Alternating Relay with Sequence Locking Switch special function triplexor alternating relays from the ATC Diversified Electronics Division of Marsh Bellofram are designed three-load installations. This unit has a field selection switch that is used to lock the alternating relay into a desired sequence. The model ARA-120-AJE has the option of automatically alternating on each load cycle or by external clocking, while allowing for additional loads to run in the event of excess load requirements.
