The signal input part of device equipment operation.
The explanation signal transmission by taking one enters the 86 box external input terminals connection on-off type equipment regulation process that two go out as an example below
Process in 86 box of external communication power supply when 220V, turns pressure by AC-DC power conversion module, provides work to other devices
Reach normal operating conditions as voltage, and powers from port is drawn to control panel is above connect, after control panel powers on, corresponding program
It brings into operation.
86 box work-based logics are as follows:
Original state: photoelectric coupled circuit input signal external connection end 52 and photoelectric coupled circuit input signal ground terminal 58 are in and disconnect shape
State, the voltage (being initially 12V) of photoelectric coupled circuit input signal external connection end 52, without voltage difference, lead to photoelectric coupled circuit compared with 12V
Middle light emitting diode does not shine, so that photoelectric coupled circuit another side contact is not connected with grounding terminal (GND), so photoelectric coupled circuit is defeated
The level of signal control terminal 37 will not change out, remain high level.Because photoelectric coupled circuit output is high level, according to journey
Sequence logic judgment, so that No.1 relay electromagnetic signal control terminal 32 is low with No. two relay electromagnetic signal control terminals 34 simultaneously
Level, external-connected port No.1 relay signal exports outer end 57 and No. two relay signal output 60 voltages of outer end are constant.
(initial: 57 ends are 0V, and 60 ends are 12V)
When external on-off type sensor (such as water stain sensor, gas security) alarm type, photoelectric coupled circuit input letter
The voltage for having dragged down the input terminal 52 of photoelectric coupled circuit, this time is connected in number external connection end 52 and photoelectric coupled circuit input signal ground terminal 58
Light emitting diode both ends have voltage that it is made to shine in coupling circuit, and the contact and ground line of the another side of photoelectric coupled circuit are caused after shining
End (GND) conducting has dragged down the level of photoelectric coupled circuit output signal control terminal 37, and the level of output end becomes low level at this time.When
Programmable detection to optocoupler output be low level when, according to the logic judgment in program make No.1 relay electromagnetic signal control
End 32 and No. two relay electromagnetic signal control terminals 34 become high level simultaneously, and external-connected port No.1 relay signal is caused to export
Outer end 57 and No. two relay signal output 60 voltage reversals of outer end (57 ends are 12V, and 60 ends are 0V), reach control access
No.1 relay signal exports the purpose of the equipment of outer end 57 and No. two relay signal output 60 ports of outer end.Conversely,
Return to original state.
By taking combustion gas controls as an example, the first terminals of direct current cathode output end 46, the first wiring of DC output end ground wire
End 48, photoelectric coupled circuit input signal external connection end 52, photoelectric coupled circuit input signal ground terminal 58 are separately connected gas alarm sensor
Respective terminal, No.1 relay signal exports outer end 57 and No. two relay signal output outer ends 60 connect a machinery
Arm, mechanical arm connect combustion gas arm, export outer end 57 by No.1 relay signal and No. two relay signals export outer end
The positive and negative rotation of the state control mechanical arm of 60 output voltages, combustion gas arm is further pulled by the positive and negative rotation of mechanical arm, is promoted
Valve turns on or off.
Application of the invention realizes the state that 86 boxes input regulation output signal by external electric signal, into one
Electric operation outside step control, can also export DC12V, and can connect 485 communication equipments and carry out signal transmission, make a letter
86 single boxes realize functional diversities application, have saved application cost, have improved the utilization rate of 86 box inner spaces.
