261-D-120
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. -

2611-120
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
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. -

310-120
The Model 310 Programmable Timer is a universal timer designed to replace over 20 standard timers. Each Model 310 can be set for one of five functions in four timing ranges, and is available in three voltage ranges. The digital design of the Model 310 provides high accuracy repeatability and response time. The heavy-duty output relay carries loads up to 10 amps at up to 240 volts AC, resistive. Programming is accomplished by simply installing jumper wires between two or more socket pins. An LED indictor illuminates when the relay is energized.
