Very informative and easy understandable video. Thanks a lot. :)
This is great thanks!
Thanks. You helped me a lot.
Excelente explicación
Outstanding... thanks
Thanks for sharing master
amazing information! Tnks
Best video for saftey relay
Thank you wonderfull
So good! Congrats!!!!!
thank u i like this kind of videos
Thank you
Or we can use 23-24 for K2. I think it's better option :)
nice
Thanks.
Good presentation 👍 make more videos related to safety relay like Allen Bradley gsr di safety relay 440r-d22r2
I agree with you!
If we dont use in S11 and S21, How about the needed signals for S12 and S22 (0V or 24V)?
Hi
AboutElectricity
Can you create Video about Wiring safety relay XPS-AC5121 of Schneider Electric
can you do FX5U-32ME/ES mitsubishi
Hello, can you tell me which program are you using?
Thanks for your video. It's very helpful. But can you help me to explain how does the reset contact work? Thanks a lot.
Simple.Whenever you e-stop the machine to energize the safety relay back again you will need to press reset button.
@@AboutElectricity great!
Hi Dear. I am wondering if you could help me with my project. I am rebuilding an old cnc milling machine with new components , but keeping old safety relay . It is an Omron.
Hello AboutElectricity, I've got a question. I notice that you don't have the E-Stop button wired into any 24V in the video. Why is that? I'm assuming, that whenever channel 1 and 2 are happy and you hit your reset, it sees both channels are closed then and that allows the relay to latch? An answer would be awesome!
Maybe I'm just confusing 24v e-stop daisy chained circuits to the pilz, which I'm not entirely sure what all the differences are yet.
Also, what are the 13 and 14 terminals for? From my understanding it looks like it keeps power latched onto the coil for the contactor(s), for whenever the circuit isn't tripped.
1.yes.You only wire 24V to power the relay and e-stop button to the monitoring channels. During reset if booth are closed then the relay turn on the safety outputs 13-14.If for some reasons we will lose one channel the safety relay will de-energize safety outputs.
@@AboutElectricity Thanks for such a quick response! I believe I understand it pretty clearly now. This helped a lot for troubleshooting ideas for work. Thank you!
@ryanjohnson3606 The unit itself sends a 24 through the e-stop from S11 and S21 and monitors that it receives the signal on S12 and S22. When it loses the 24 signal (when you push the E-stop) it will then open the contacts for the circuit it is controlling. This is then reset when the e-stop is pulled out (can see the signal again) and when it gets a pulse signal from the reset (terminal S33 to S34)
Hopefully I explained that clearly.
Hello Aboutelectricity
Will it be the same if you wire channel by channel; like fro s11 through E-stop to S21 and from S12 through E-Stop to S22?
No. Terminals S11 - S12 is one channel and s12 - s21 is the second channel.

How to connect this relay with electro-mechanical switch
Só faltou numerar a contatores, não sei se usou contato aberto ou fechado.
Hi, couldn't the reset bypass the contractors and just go 33 to reset then straight back into 34. Or is this done to make sure a short hasnt developed on the contacts themselves.
Thanks
Normally you wouldn't put the reset circuit through the n.c. contacts on the relays. You would just wire the n.o. reset button on the S33 to S34 terminals. The n.c. contacts on the relays are then free to use as feedback to the input card on the plc or simply an indicator light.
Porque esran en serie k1 y k2??

Depending on the performance level you want to achieve. Check ISO 13849 standard for details.
Can i connect feedback circuit to two relays in series instead of contactors ? why would just not connect NO contact reset between s34 and s34?
1.I have seen many machines and they have always been fitted with contactors.It is because those contactors are switching main circuit where current is higher and might exceed rated load of the relay contacts.
2. If your application does not require feedback circuit then yes, you can wire only NO contact between s33 and s34 as manual start.
@@AboutElectricity Thank you for quick reply. I am working on low voltage 24vdc circuit, outputs are pneumatic sv 24vdc dump valve 24vdc buzzer 24vdc ect., inputs are sensors that are 24vdc.
I think in low voltage circuits i can use small 24vdc relays with safety relay 24vdc? correct me if i am wrong..
Another question is that in small machines based on PLC with maximum 8 inputs and outputs - push buttons, proxy sensors, solenoid valves, buzzers, dump valves all operating on 24vdc - i would need to implement safety circuit - means e-stop and safety relay, there is no guards that would require interlocks or light curtains.. all i need to drop air from the pneumatic system and trigger buzzer at the event of emergency machine stop (e-stop depressed)
1.) would be necessary to disable inputs 24vdc?
2.) would be necessary to disable outputs 24vdc?
3.) would be just connecting pneumatic dump valve and buzzer to safety relay with 24vdc relays in series?
Regards,
D.
@@yattaman71 I would still use contactors instead of relays.I would wire safety relay with emergency stop like here ruclips.net/video/SYkYQCfPVPI/видео.html
When E-stop depressed two contactors will drop out disconnecting power supply to the valves.On top of that,use one set of contact and wire it to the plc and plc program should deenergize all outputs.But you have to chceck if it works.
@@AboutElectricity Hi, Thanks for help on this matter. Would you be able to explain how to connect remote pneumatic dump valve 3/2 24vdc. to the safety relay ?
The purpose of using aux contacts on contactors is to prevent a safety circuit reset in case of a contact weld in one of the contactors. You would also use a safety rated contactor that's built differently than a standard model.

Thanks.

I use pliz pnoz x3
After couples years when I want to reset it never reset
need to switch of power and then reset
Well, you have to check feedback circuit. It looks to me that some of the normally closed contact is not really closed ( and it should be).Check how many NC contacts you have in the feedback circuit then take a multimeter and check the voltage before and after each contact.
I agree with you on "milion dollar business".Every electrical part that has word "safety" in it cost a fortune :)
@@AboutElectricity I use it to check for emergency loop
I am sure that all push button
and NC keys are OK
I use all inputs for
emergency in different places(one machine) AND different machine(press machine,glaze line, wrap carton, ball mill with a 1 MW electromotor ,....... in tile company desined by SACMI)
It has no problems at the beginning of use, but it does have problems over time and needs to be turned off once to reset
Kon c aap me ye graphics bnaye hen???

Please someone give me an explain or something to read about benefit of using automatic reset safety device over making same circuit without using a safety device.
Nowadays, in every machine in the factory where safety is taken seriously, only safety relays are used.
Type in google "machine safety categories explained".
Manual lin send kro
Shouldn't one contactor come from 13,14 the other from 23,24. You have spent all this money an have a single contact failure in the pilz bringing it all down.
This is what led me to this video. Each single contact in safety relay is made in fact from two relays connected in series - is it sufficient to satisfy category 3/4 circuit?
No se ve
The safety relay will not give enough power to activate a contactor.
What makes you think so ?
@@AboutElectricity I've wired these up before. You need a separate 24v supply. For the contacts.
@@chrisperry6746 I work with them every day. It has nothing to do with safety relay. It is up to your power supply. We use 5A or 10A power supply and they power whole machine ie. a couple of safety relays,valves and many, many relays and contactors.
@@AboutElectricity
Sorry I should of been more clearer. The current going through the two channels. Won't be enough to power a contact.
@@chrisperry6746 I still disagree with you. Pilz pnoz technical details says that safety contacts at 24VDc have got Imax = 6 A. Is your contactor coil taking more than 6A ?
Attention le câblage est faux !!!! la bobine de K2 (A- A2) entre 24 et 0V. ne pas oublier de relier +24V à 23.
Thank you
