261-S-24
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…

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…

403
***DISCONTINUED*** Check out the Model 403D. The 403 Liquid Level Controller provides central control of duplex pumping systems. The Model 403 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.

404-115V
The Model 404 Liquid Level Sensor operates in conjunction with a Model 403 Controller for bubbler-type duplex pumping systems. The 404 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. The Model 404s four outputs are designed to replace…

408-115
The Model 408 is a 5-level liquid level sensor designed for use with bubbler-type systems. The 408 contains an internal air pressure transducer; the user must provide a small air compressor capable of supplying a maximum of 15 psi. This operates the system to a liquid depth of 34.6 feet. The output of the 408…
