261-D-12

261-D-12

261-Series, Alternating-Relays

The Model 261 series Alternating Relay is designed for duplex pumping systems where it is desirable to equalize pump run time. The solid-state alternating circuit drives an internal electromechanical relay. A continuous power source and control switch are required. The control switch (float, pressure or other isolated contact) is connected between the L1 terminal and the control terminal. Each time the control switch is opened the output contacts will change states. Indicator lights on the case show the internal relay status. On the optional toggle switch versions, the toggle switch is set to the ALTERNATE position. Setting the switch to Load 1 or Load 2 will lock the relay in position, preventing alternation.

2611-Series, Alternating-Relays

Model 2611 Alternating Controllers are microprocessor-based designs for use where two loads are required to alternate for equal run time. LED indicators show status of the units three contact switch inputs and two load outputs. The controllers lead select switch allows loads to alternate normally in the center position, or disable automatic sequencing and lock in a 1-2 or 2-1 sequence. When a Stop, Lead, or Lag switch closes – corresponding LED atop the Model 2611 illuminates.


261XBXP-120

261XBXP-120

261XBXP-Series, Alternating-Relays

The Model 261XBXP(R) Alternating Relay uses the same solid-state latching and control circuit as all the other 261 series models, the enclosure and the connecting base being the major differences. This version was designed to replace a long time and widely used mechanical latching relay offered by another manufacturer. The modern circuitry used the Model 261XBXP offers a vast improvement in reliability and useful life over the mechanical type. The XBXP version of the relay requires closing the control switch to begin alternation, and the XBXPR version requires opening the control switch to begin alternation. Replacement of the original mechanical alternator with the Model 261XBXP requires the addition of wire from L1 to Pin 5 of the connector in order to supply continuous power to the solid-state circuit. Available in two voltage versions for use with 24 VAC/DC or 120 VAC/DC.

271

271

271-Series, Alternating-Relays

The Model 271 3-Stage Alternator is designed to control the motor starters in a stage pumping or compressor system. Its purpose is to ensure that only the required motors are used, and that each motor receives the same average amount of run time. Motors are sequenced in a first-on, first-off cycle. Potential uses include water supply systems, air compressor systems, sewage disposal plant systems, storage tank filling or emptying systems, water recycling systems, irrigation systems or sump pump applications.
