Description
Technical field
The invention belongs to field of signal transmissions, be specifically related to a kind of based on conveyer in the set of signals of switching value.
Background technology
In the current automation equipment, the control signal of the overwhelming majority is to be main with switching value.Wherein, input unit comprises photoelectric sensor, magnetic sensor, proximity transducer etc., and output device comprises electromagnetically operated valve, relay etc.
The installation site of input/output device in automation equipment disperses often very much, and the I/O unit of PLC then is to concentrate on equipment somewhere, or is dispersed in several main places.At this moment; Will there be following drawback in conventional signal transmission form: if all input of one of which, the I/O unit that the output signal is connected to PLC independently; Holding wire will be very many, and not only cabling is not attractive in appearance, and the inspection circuit is also very inconvenient; If two, have other input output device to damage, thread-changing also bothers very much; Three, during indivedual magnetic switch sensor signal; Only show the closed or disconnection of circuit; And do not possess the function of pointing out the current demand signal state, just be difficult to judge that for the attendant current sensor status is that closure or disconnection perhaps are difficult to judge that transducer is in normal condition or in damaged condition.
Summary of the invention
The purpose of this invention is to provide a kind ofly based on conveyer in the set of signals of switching value, conveyer can focus on the signal that inputs or outputs at certain position in this set of signals, has greatly reduced the cabling workload simultaneously.
For realizing the foregoing invention purpose; The technical scheme that the present invention adopted is: a kind of based on conveyer in the set of signals of switching value; Conveyer comprises transmission ends plug in external connection end plug and the set of signals in this set of signals; The external connection end plug is provided with first positive terminal, first negative terminal and signal terminal, and the transmission ends plug is provided with second positive terminal, second negative terminal and several signal transmission terminals in the set of signals; Said first positive terminal links to each other through electrode line with second positive terminal, and first negative terminal links to each other through negative line with second negative terminal, and signal terminal links to each other through holding wire with the signal transmission terminal.
Simultaneously, the present invention can also be able to further realization through following technical measures:
Said signal transmission terminal is set to 8.
Be connected with the operating state detection module between said electrode line and the holding wire that is connected signal terminal and arbitrary signal transmission terminal.
Said operating state detection module comprises light-emitting diode, and the positive pole of light-emitting diode links to each other with electrode line, and negative pole links to each other with holding wire.
Said operating state detection module also comprises the resistance that is connected in series with light-emitting diode.
Said operating state detection module also comprises the fuse that is connected in series with light-emitting diode.
Preferably, said fuse is the self adaptation fuse.
Beneficial effect of the present invention is:
1, the present invention uses a circuit board to focus on the input at certain position, output signal.Gather 8 the tunnel through a special signal transmission line and input or output signal, and transfer signals to the input/output module of PLC, and then significantly reduced the workload of cabling.
2, the present invention also is provided with a resettable fuse at the 24V feeder ear.Then when circuit broke down or be unusual, resettable fuse was phase step type and adjourns high-impedance state, and the electric current quilt is pinch off rapidly, thereby circuit is carried out fast and accurately limiting and protecting; After outage or fault eliminating, resettable fuse reverts to normal operating condition, and need not artificial the replacing.Can the equipment of inputing or outputing of periphery be effectively protected after resettable fuse is installed, avoid causing components from being damaged because of short circuit or other factors.
3, when external world's equipment of inputing or outputing breaks down the needs replacing, as long as the external connection end plug is removed, and replacing gets final product again, and replacing of the present invention thus is very convenient.
When the signal demand that 4, inputs or outputs equipment when the external world is drawn, because inputing or outputing the standard configurations lead-in wire of equipment, great majority do not possess the drag chain function, so the phenomenon that is easy to fracture from moving-member (like the tank band).And after adopting this device, as long as use 10 core flexible cables just can guarantee the normal use of holding wire.
5, because this device is near the external world inputs or outputs equipment, to install nearby, so do not have special requirement to inputing or outputing equipment standard configuration wire length, what sensor lead was short slightly also can use, and does not prolong lead-in wire and need not increase joint.
6, compact in design of the present invention and volume are little, and can take guide rail or screwed hole mode to fix, and are convenient to operation.
