Abstract
An improved contactor control system comprising several modules, such as a contactor module, an overload/controller module, a communication module, a bell alarm module, and a power terminal module which are electrically interconnected through a plug-in unit, and mechanically interconnected through one or more snap-in units, and which modules can be interchangeable and arranged relative to the overload/controller module according to a particular industrial application.
Claims17
A contactor control system for operating a load, comprising:
- contactor module means for operating said load, overload module means associated with said contactor module means, said contactor module means and said overload module means including means for electrically and mechanically connecting said overload module means external to said contactor module means with said overload module means independently supported by said contactor module means.
A modular contactor system for controlling energization of a load for a power source, said system comprising:
- a plurality of modular units including a contactor modular unit for selectively connecting said load to said power source, and
- at least two additional modular units each including means for providing a different additional function operatively associated with said contactor modular unit,
- said contactor modular unit and each of said additional modular units having plug-in connector means for selectively electrically connecting said modular units together in various arrangements, said plug-in connector means including a plurality of electrical connections for exchanging signals and for identifying one of said additional modular units to the other of said additional modular units and for sending information therebetween in order to function based on operational conditions in said system.
A modular contactor system for controlling energization of a load for a power source, said system comprising:
- a plurality of modular units including a contactor modular unit for selectively connecting said load to said power source, and
- at least two additional modular units each including means for providing a different additional function operatively associated with said contactor modular unit,
- said contactor modular unit and each of said additional modular units having at least one plug-in connector having means for selectively mechanically externally connecting said modular units together and means for selectively electrically connecting said modular units together in various arrangements.
