339-120-10
The Model 339 On/Off Delay Relay is an electronic time delay relay which provides two functions: on delay, and true off delay. The true off delay, (relay remains energized for a delay period when power is removed) is provided by means of an internal latching relay. Each time delay, on and off, is separately adjustable to a maximum of five minutes on or off. The Model 339 uses the same pin-out configuration as standard time delay and general purpose relays. It can be used in new or replacement applications for thermal, pneumatic, or spring-wound timers, or in place of general purpose relays or other electronic timers. -

4092-120
The Model 4092 Dual Seal Failure Detector is designed specifically for monitoring the shaft seals of two submersible pumps. The probes are installed in the seal cavities of each of the pumps. When a seal begins to leak, contaminating fluid enters the seal cavity, lowering the resistance between the probe and the common connection. If the resistance drops below the sensitivity set-point, the corresponding relay and the LED indicator are activated. The Model 4092 will automatically reset when the fault condition is corrected. The sensitivity is field adjustable. -
4092I-120
The Model 4092I Isolated Dual Seal Failure Detector is designed specifically for monitoring the shaft seals of two submersible pumps. All electrical inputs are totally isolated from each other. The probes are to be installed in the seal cavities of each of the pumps. The sensitivity is field adjustable. When a seal begins to leak, contaminating fluid enters the seal cavity, lowering the resistance between the probe and the common connection. If the resistance drops below the sensitivity set-point, the corresponding relay and the LED indicator are activated. The Model 4092I will automatically reset when the fault condition is corrected.Also available in a 240 VAC version, ask for details.

4093-120
The Model 4093 is a compact, socket mounted Liquid Level Controller that operates by monitoring the conductive liquid resistance between two probes. The unit monitors two liquid levels and responds as a pump-up or pump-down control as determined by the switch setting on the top of the unit. The green LED indicates pump operation while the potentiometer allows the user to adjust probe sensitivity. -
441-120
The Model 441 Multi-Stage Alternator is designed to control the operating sequence of multi-stage motor/pumping systems. It can also be used to maintain the desired level of pressure-on air compressor systems. Four motor select DIP switches located on the front panel allow the alternator to control a single-motor/pump, two-motor/pump, three-motor/pump or four-motor/pump system. The Model 441 will assure that only the necessary motors/pumps are operating, and that the run time for each motor/pump is approximately equal. Motors are sequenced first-on, first-off. If the motor/pumping demand requires only one motor/pump at a time, the alternator will start the next motor/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 441 include water supply systems, sewage disposal plant systems, storage tank filling systems, air compressor systems, irrigation and water recycling systems.

553-01
The Model 553-01 Re-Acceleration Relay is designed to take the place of a voltage sensing relay and two time delay relays. When voltage is applied to the Model 553-01, and the external start switch is closed, the adjustable on-delay time begins. After the delay period, the contacts will close. If the line voltage drops below 90 volts, the contacts open and the true-off delay begins. If the voltage rises above 105 volts before the true-off delay has elapsed, the contact will re-close. If voltage is not restored to 105 volts before the true-off delay time period ends, the contacts will remain open until the external start switch is closed. -

64-5
The Model 64-5 Power Factor Regulator is a monitoring and power factor control system. It is designed to help obtain an improved power factor, with a minimum of added capacitors. This device uses a unique phase-angle sensing circuit to monitor the power factor of a 3-phase power line. The Model 64-5 automatically responds to changing power factor by closing or opening the internal relays, which add or subtract capacitor banks on the line. Although intended for 115VAC 60Hz systems, other voltage or frequency models may be available. -
