Abstract
The utility model provides an eight-loop flash alarm, relates to an industrial automation instrument and is particularly suitable for the malfunction alarm of a field apparatus. The utility model is characterized in that: a relay and a signal output terminal array are welded on an output board, while the signal input terminal array is welded on an input board; other elements which are connected with one another are welded on a main board; the output board and the input board are respectively welded on the main board through a bonding pad; the chip EM78P447S receives an external switch signal and output a lever signal to the array to drive a contact of the array to actuate and the chip, at the same time, sends out a contact signal to get a buzzer and an LED which are connected with the chip electrified to give an audible and visual alarm consequently; the eight-loop flash alarm is provided with the audible and visual alarm and special eight-loop signal input on the basis of the prior flash alarm, so when any one of monitored eight devices fails to work, a corresponding channel of the eight-loop flash alarm gives a flash alarm, thereby greatly improving the utilization rate and making the alarming states more clear and diverse.
Description
Technical field:
The utility model relates to industrial instrument and meter for automation, is specially adapted to the industrial field device fault alarm.
Background technology:
At present industrial fault alarm instrument mainly by contact point signal Input terminal block, integrated processor, relay, etc. form, can detect the equipment failure signal, and provide one group of switching value alerting signal by relay, can realize fault alarm substantially.But its type of alarm of this alarm is clear and definite inadequately and the warning passage is few, usually makes the industrial operation personnel can't know the commercial unit fault during relay damaged that output signal is used or during external electric bell fault, thereby has caused the frequent generation of industrial accident.
The utility model content:
The purpose of this utility model is in order to overcome above-mentioned defective, and a kind of eight loop flashing light alarm instrument of being made up of: mainboard, output board, tablet, light emitting diode, chip EM78P447S, hummer, three group of 3 core contact pin and jumper cap, relay, signal output terminal row, signal input terminal row, power supply unit etc. are provided.
Its solution is: a kind of eight loop flashing light alarm instrument, by: mainboard, output board, tablet, light emitting diode, chip EM78P447S, hummer, three group of 3 core contact pin and jumper cap, relay, signal output terminal row, signal input terminal row, compositions such as power supply unit, it is characterized in that: relay, signal output terminal row be welded on the output board, signal input terminal row be welded on the tablet, all the other elements are welded on the mainboard and interconnect, output board is welded on by pad respectively again with tablet its element is connected with each element on the mainboard, switching signal is gone into integrated chip EM78P447S by the signal input terminal dispatch, level of output moved to the contact that this level signal of relay has driven relay after integrated chip EM78P447S received the make and break contact signal, and while integrated chip EM78P447S is sent out a contact point signal makes connected buzzer circuit and circuit of LED get; Three group of 3 core contact pin is housed on the mainboard, all connects with integrated chip EM78P447S weldering, the slotting method of cooperation jumper cap can realize the switching of difference in functionality;
Also include 8 light emitting diodes on its mainboard, be welded on the mainboard, the flashing light alarm in corresponding eight loops respectively, preceding four the tunnel what adopt be red light emitting diodes, back four tunnel employings be green LED.
The utility model advantage is not only to have comprised traditional relay switching variable signal output, light emitting diode and hummer have also been increased newly, the sound and light alarm signal can appear when fault alarm, make alarm condition clearer and more definite, eight loop flashing light alarm instrument are supported the switching value signal input in 8 loops simultaneously, can monitor the working condition of 8 commercial units simultaneously, in 8 equipment of its monitoring any one when breaking down, flashing will appear in the light emitting diode of eight loop flashing light alarm instrument respective channel, signal is reported to the police, the efficient of fault alarm is improved greatly, reduced accident rate.
Description of drawings:
Accompanying drawing 1 is the utility model eight loop flashing light alarm instrument structure block diagrams.
Accompanying drawing 2 is the circuit theory diagrams of chip EM78P447S.
Embodiment:
A kind of eight loop flashing light alarm instrument, by: mainboard, output board, tablet, light emitting diode, chip EM78P447S, hummer, three group of 3 core contact pin and jumper cap, relay, signal output terminal row, signal input terminal row, compositions such as power supply unit, it is characterized in that: relay, signal output terminal row be welded on the output board, signal input terminal row be welded on the tablet, all the other elements are welded on the mainboard and interconnect, output board is welded on by pad respectively again with tablet its element is connected with each element on the mainboard, switching signal is gone into integrated chip EM78P447S by the signal input terminal dispatch, level of output moved to the contact that this level signal of relay has driven relay after integrated chip EM78P447S received the make and break contact signal, and while integrated chip EM78P447S is sent out a contact point signal makes connected buzzer circuit and circuit of LED get; Three group of 3 core contact pin is housed on the mainboard, all connects with integrated chip EM78P447S weldering, the slotting method of cooperation jumper cap can realize the switching of difference in functionality;
Also include 8 light emitting diodes on its mainboard, be welded on the mainboard, the flashing light alarm in corresponding eight loops respectively, preceding four the tunnel what adopt be red light emitting diodes, back four tunnel employings be green LED.
The attainable function of jumper cap on the mainboard and 3 core contact pins combination back has: input signal high-low level warning function, buzzer switch function, warning memory function;
Also include the ann silence end on the signal output terminal row, when operating personnel need report to the police affirmation or warning release to single loop flashing light alarm instrument, can be by the affirmation of reporting to the police of external button or short circuit COM end and noise reduction end, after having confirmed warning, the relay no-output, the respective channel light emitting diode does not glisten, and hummer does not ring, and waits for when report to the police next time and moving once more.
