Phase II Proposal - Relay Replacement

Lewis Innovative Technologies, Inc. (LIT) has, under Phase I efforts, developed an electronic relay design capable of serving as a replacement for N-130 relays used on Navy CVN 68 class ships . To accomplish this, LIT has developed and utilizedproprietary techniques (Patent Pending) utilizing MOSFET technology to control alternating current power. In addition, LIT has developed monitoring/triggering circuitry to serve as the sensing coil of the relay which determines, based on preset voltagelevels, when the relay is to pick up or drop out and provides the triggering signal to the switching block of the relay. LIT's unique approach allows for voltage threshold levels to be preset with dip switches and does not require the cumbersome springadjustments of the current electromechanical N-130 relays. The LIT unit is set unless the pick up and drop out voltages are required to be changed. These circuits combine to function as an N-130 relay but with the added benefits of: No moving parts No contact arcing or burn No switch bounce Improved Reliability Ease of Use and Set-up Modular Design Bolt-In Replacement Status LEDs/Fault Isolation Bypass/Override Capability Reduced Inventory and Cost Obsolescence Avoidence Capability of Intelligent Control Quieter and Safer OperationBENEFITS: The availability of an all-electronic replacement for the N-130 relay is the immediate result of the success of this phase II research.At the completion of this work LIT will be producing reliable, readily available replacements for the N-130 relay. These units will be a form, fit and functionally equivalent drop in replacements for existing N-130 relays with improved performance andenhanced operating capabilities. These units will be easier to set-up and use than the existing N-130 relay and will have more capabilities for other applications on naval vessels.Additionally, LIT is developing a growing line of electronic relays and circuit-breakers, with the N-130 relay replacement as the cornerstone of this product line. This product line will include instrumented and intelligent relays that will allow the userto monitor operating conditions and even control relays remotely.
