Abstract
The utility model discloses a kind of controllable scram button audible-visual annunciator, a kind of controllable scram button audible-visual annunciator can not only realize the sound and light of alarm after scram button triggering, sound and light of alarm can be enabled or disabled by external hand controlling switch simultaneously, and there is the whether effective indicator function of sound and light of alarm.The utility model has the advantage of：After scram button is triggered, indicator lamp and electric bell work simultaneously, send sound and light alarm, timely remind field personnel, if user is without sound and light of alarm, sound and light of alarm can then be closed by external hand controlling switch, in addition field personnel can also be very easily by the light on and off of light emitting diode, to learn whether sound and light of alarm is activated.
Description
Technical field
It the utility model is related to a kind of audible-visual annunciator, especially a kind of audible-visual annunciator for scram button.
Background technology
Scram button used in Industry Control scene at present, do not possess the function of prompting user after triggering.Jerk is pressed
After button is triggered, it is not easy to be discovered by user, difficulty is brought to staff scene investigation failure.In order in jerk
Button timely reminds user after being triggered, the utility model just arises at the historic moment.
The content of the invention
The purpose of this utility model is to provide a kind of controllable scram button audible-visual annunciator, can not only realize jerk
Button be triggered after sound and light of alarm, while sound and light of alarm user can manually controlling switch carry out it is flexible
Selection, overcome after existing scram button is triggered without prompting the problem of.
The technical solution of the utility model is：A kind of controllable scram button audible-visual annunciator by using indicator lamp and
Electric bell realizes the sound and light alarm after scram button triggering, while realizes sound using hand control switch and electromagnetic relay in circuit
The outside control of light alarm function, realize that sound and light of alarm is by controlling the light on and off of light emitting diode in circuit in addition
No effective state instruction.
The controllable scram button warning circuit includes AC220V indicator lamp ZM, model XB2-BVM；AC220V electric bells
DL, model UC4-100mm；Electromagnetic relay J, model HTD2-DC5V；Resistance R, the fixed carbon resister of model precision 5%；
LED, the common red light emitting diodes of model；Manual control function switchs SW, model KCD3；Battery pack
Bat, model NI-CD AA 700mah；A points connection 220V AC power live wire L, b point connection 220V AC power zero lines N；c
Point and d points are the increased one group of normally opened contact of scram button, and c points are connected by wire with a points, and d points are wired to finger
Show lamp ZM and electric bell DL；E points and the normally opened contact that f points are electromagnetic relay J, e points are connected by wire with b points, and f points are by leading
Line is connected to indicator lamp ZM and electric bell the DL other end；One end of electromagnetic relay J coils and the anode of LED connect
Battery pack Bat positive pole is connected to, the negative electrode of LED is connected with resistance R one end, resistance the R other end and electromagnetism
The other end of relay J coils is connected to hand control switch SW one end, hand control switch the SW other end and battery pack
Bat negative pole connection.
The utility model has the advantage of：After scram button triggering, indicator lamp and electric bell work simultaneously, and sound and light alarm can
Field personnel is timely reminded, many unnecessary troubles can be reduced on site fault clearing, it is time saving same
When can also improve the operating efficiency of equipment production, manually controlling switch and electromagnetic relay realize sound in this external circuit
The outside control function of light alarm, if staff does not need sound and light of alarm temporarily, it can control hand control switch will
Sound and light of alarm is closed, and adds the application flexibility of the utility model.
Brief description of the drawings
Fig. 1 is the circuit diagram of controllable scram button audible-visual annunciator.
Embodiment
220V AC powers are accessed first between a, b, hand control switch SW are closed, electromagnetic relay J coil
Both ends are powered, electromagnetic relay J opened point both ends e and f conducting, while LED bright light, prompt sound and light alarm work(
It can be activated, after scram button is triggered, the normally opened contact both ends c and d of scram button are turned on, then indicator lamp ZM and electric bell
DL is powered simultaneously, sends sound and light alarm.
Hand control switch SW is disconnected, electromagnetic relay J coil both ends power-off, while LED does not work
Lamp, sound and light of alarm is prompted to be closed, electromagnetic relay J opened point both ends e and f open circuit, now no matter scram button is
No to be triggered, indicator lamp ZM and electric bell DL are all without energization, so sound and light of alarm is manually controlled closing.
