  404/408D

  Liquid Level Sensor
  Read more
  The Model 404/408D Loop to Switch Converter converts 4-20mA or 0-15psi inputs to control of up to 8 optically isolated 4-20mA outputs.It can be used for a variety or applications where control from a 4-20mA input is useful, or for pumping applications with either 4-20mA or 0-15psi inputs.

  For non-pumping applications, this allows control of up to 8 devices from a single 4-20mA source, with LCD monitoring of current level and individual status LEDs for which outputs are active. For pumping applications, the 404/408D contains an air pressure-to-voltage transducer and requires only a small air compressor capable of 15 psi to operate the system down to approximately 35 feet, with LCD display that shows liquid depth in feet.

  The Model 404/408Ds eight outputs are designed to replace the float switch inputs to a Model 403 or model 407, or to be used with a Model 448 output Relay Board. A 4-20mA signal output provides for other control applications. A 3-digit LED display continuously shows the current level (mA), liquid level (to a tenth of a foot), or both. LED indicators illuminate as the levels are exceeded.

  30-600

  High Voltage Multifunction Timer
  4 ranges (0.1 Sec. – 1023 Hr.)
  Read more
  The Model 30 is a High Voltage Multifunction Timer.
  The digital design of the Model 30 provides high accuracy,
  repeatability and response time. The output of the Model 30 is
  a heavy-duty DPDT electro-mechanical output relay.
  Four DIP switches select one of four timing functions and one
  of four timing ranges. Delay time is set with a 10-position DIP
  switch. When timing either the red LED will blink indicating the
  relay is de-energized or the green LED will blink indicating the
  relay is energized. On completion of the delay period either
  the red LED lights indicating the relay is de-energized or the
  green LED lights indicating the relay is energized.
  240-480V operation is available, ask about the model 30.

  60-240V

  Bistable Impulse Latching Relay
  Read more
  The Model 60 is a Bistable Impulse Latch Relay. When power pulse is applied, the Impulse LED on the top of the relay will illuminate and the relay will change state. Power can then be removed and the relay will remain in that state (mechanical latch). When power pulse is reapplied, the relay will change state and latch.

  386

  Countdown Timer
  Treatment Timer
  Read more
  The Model 386 Count Down Timer is a timer with an audible alarm output. It is housed in a standard wall switch enclosure for easy, permanent installation. The Model 386 timer was designed as a “treatment timer” and is useful in areas requiring an audible alarm at the end of a treatment, such as a tanning bed.The Model 386 is knob-adjustable from 1 to 60 minutes. There is a user replaceable 9V battery inside and should provide one to six months of operation. The previous set time is remembered each time the battery is changed as well as when the timer wakes up; this allows for easy repeatable timing without the need to adjust the knob. There are two LEDs; the upper one is the timing/timed out, and the lower one symbolizes “set mode” and low battery information. Note: To change the time, press and hold the button until the lower LED begins flashing green, when finished, press the button again to “lock-in” and store the value.

  407D

  3-Pump Liquid Level Controller
  Read more
  The Model 407D 3-Pump Liquid Level Controller provides central operating control of triplex pumping systems. The solid-state electronic controller provides alternating of load pumps, low level cutoff and high level alarm outputs. Runtime meters provide instant visual data on total running time of each pump motor. LED indicators show ON/OFF status of each pump. The 407D has five level-sense inputs which can be activated by float switches or other level sensing devices which provide a switch closure.

  403D

  Liquid Level Controller
  Read more
  The 403D Liquid Level Controller provides central control of duplex pumping systems. The Model 403D includes pump alternating, visual run-time meters, hand-off-auto control and alarm outputs. Four level-sense inputs interface with float switches, pressure switches, or other level sensing devices which can provide a contact closure.

  209-480V

  Phase Sequence Detector
  Line Voltage Detector
  Read more
  The Model 209 Line Voltage & Phase Sequence Detector can help prevent costly downtime and equipment damage by offering a quick and easy way to determine the phase sequence (ABC or CBA) and to check for missing phases in a 3-phase circuit. To use, connect the Detector to any 3-phase circuit, Wye or Delta. If all three phases are present and in the proper sequence, the ABC rotation lamp and the three line voltage lamps (A, B and C) will illuminate. An improper phase sequence will cause the CBA rotation lamp to illuminate. An open phase condition will cause both rotation lamps to flash and only illuminate two line voltage lamps. See the Condition Chart.

  The Model 209 is available in either a 208/240V option or a 480V option. Both models can be used in a three phase circuit with a frequency of 50Hz, 60Hz or 400Hz.
