  27

  TRUE RMS Over & Under Current Monitor
  0 – 5A
  Read more
  Model 27 True RMS Current Monitor has a display that shows the current with an accuracy of +/- 0.5%. The display is updated every second and re-initialized every 30 seconds. Model 27 has a rotary encoder with switch on the unit. By pressing the encoder switch for more than 5 seconds, the unit will enter the setup mode. This unit has a user selectable relay option for High-Low or DPDT. It can also be user-selected to energize on fault or de-energize on fault. The user can select automatic or manual restart on the Model 27. The SG version of the Model 27 has silver with gold flash contacts for low current applications. Model 27 True RMS Current Monitor can be either calibrated using a True RMS Multimeter or can be restored to factory defaults in the field.

  261XBXPR-24

  Alternating Relay
  Read more
  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.

  2611-24

  Alternating Controller
  Read more
  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.

  D471

  Multi-Stage Alternator
  Read more
  The Model 471 Multi-Stage Alternator is designed to control the operating sequence of multi-stage pumping systems. it can also be used to maintain the desired level of pressure on air compressor systems. Four PUMP SELECT DIP switches located on the front panel allow the alternator to control a single-pump, two-pump, three-pump or four-pump system. Only one switch needs to be set for the total number of pumps in the system. The Model 471 will assure that only the necessary pumps are operating, and that the run time for each pump is approximately equal. Pumps are sequenced first-on and first-off. If the pumping demand requires only one pump at a time, the alternator will start the next pump in sequence each time an input switch is closed. Input switches may be float switches, pressure switches, flow switches, etc. , as required by the application.

  Potential uses for the Model 471 include water supply systems, sewage disposal plant systems, storage tank filling systems, air compressor systems, irrigation and water recycling systems.
