Description
One, technical field
The present invention relates to a kind of solid state relay, be specifically related to a kind of need not " INPUT ".Draw the novel solid relay of a plurality of Based Intelligent Control terminal CONTROL and COM ().
Two, technical background
The advantage of solid state relay is: contactless control, good reliability
The control of available electron circuit, low pressure, safety, power saving, province's equipment, no sound, but the shortcoming of existing solid state relay is: direct current " INPUT " must be provided, only have with little control big " relay function ", not popularize so use very.The advantage of contact relay is: it can expand number of contacts, by its often open, normally-closed contact, can realize various automatic control functions, the particularly time relay, do not have solid state relay to replace.But its shortcoming is too many: volume is big, materials are many, power consumption is big, the control loop high pressure is dangerous, the contact sparking, equipment is clumsy, loss is big, functional reliability is poor: many factors all may cause poor contact of contacts and be out of control, on line is many and complicated ... in a word very not " low carbonization ", but generally use it.
Three, summary of the invention
For a change the electric machine control system of huge, consumptive material, power consumption, consumption worker's heavy-current control formula now makes it " low carbonization ", invention " autocontrol intelligence solid state relay ".The advantage of integrated solid relay and contact relay, overcome the deficiency, secondary control loop electronization, intellectuality, languageization, longevityization, power saving material-savingization, microminiaturization, solidification with electric machine control system ... " low carbonization " in a word, and the management of available computer monitor.
The characteristics of " autocontrol intelligence solid state relay " are: need not " INPUT ", inner electronic control circuit is drawn a plurality of Based Intelligent Control terminals " CONTROL ": open, point, pass, along opening, opening, prohibit passs, time-delay etc. and reach COM () along closing, prohibiting, arbitrary Based Intelligent Control terminal links with COM () terminal (or touching mutually), is convenient to realize corresponding function.The power supply of internal control circuit is taken from the pressure drop (less than 2.5Vac) of this reverse-blocking tetrode thyristor.
During the control motor, with its 220 volts or 380 volts AC power of output " OUTPUT " series connection and ac contactor coil (multi-motor control system can adopt the multichannel formula), auxiliary contact with mini button and each contactor, connect each associated terminal, just can realize as: open many places, point, stop control; Draining is controlled automatically; Positive and negative stopping controlled: the Y-Δ starts control; Time-delay; In proper order; Various automatic controls such as logic, and need not any middle electrical equipment; Use the computer monitoring management, can be by optical coupled switch; It can replace or auxiliary programmable logic controller (PLC) PLC work.
Because UNICOM is the electronics input circuit, equipment is had no infringement, do not strike sparks, not electric people, not to be afraid of short circuit, safety, longevity, equipment Miniaturized.Since intelligent, languageization, and on line is simplified very much; Though control has the contact to participate in, function is to be finished by electronic circuit,, does not rely on " self-locking " contact as " self-locking " and keeps, and just triggers " opening " terminal with the contact, so functional reliability is good.
