IRIO Failure

[slychiu]

The ISM06 and ISM07 should not be used to switch 230V (assuming thatis the case from the thick wires) even though the relays are rated for 10A at 230V. This is because the spacing between the relay contacts and the other logic sections on the IRIO PCB is not far way enough so that arcing is possible.

If you need to switch higher voltage the more suitable products are IRIO-IO general IRIO and RLE02 in Din rail Enclosures,

Let me know if you would like to get this instead

chiu,


I find this absolutely astounding for you to say the boards aren\'t suitable to switch mains voltage.


What do you expect people to be using these boards for ?


I remind you that the two you post above were not available when the IRIO and the sub boards I have were released / purchased.

At that time the ISM04 was yet to be available to order, despite being posted about.


Also, take a look at this post, where a user mentions current rating of contacts, and you tell him to use the ISM06 (initially ISM07 too, but corrected by Ingo)

https://www.srcf.fr/forum/f37-beta.html

There was a lengthy discussion around these boards back when you introduced them over which was suitable for switching lighting, based on current rating of contacts, and that included the current rating between the two types of boards.
Read most of the threads in this section and you make no mention of not being suitable to switch mains voltage, only current rating.

This is why I bought the ones I did, rather than the board with lower rated contacts (which incidentally I do have too, elsewhere).


This feels so much like I was a beta tester...


The sales information says it suitable to control lights, heating and fans.

Do you expect people to fit a relay panel to switch the mains, and your relays just switch those relays ?
If so that is nuts !


To be clear here, this panel switches less than 6A TOTAL.
Each output switches as follows:

- 4 x 40w lamps (conventional incandescent)

- 1 x 60w lamp (conventional incandescent)

- 1 x 60w lamp (conventional incandescent)

- 4 x 20w step lamps (smpsu for leds in each)

- 1 x 20w lamp (cfl)

- 1 x 20w lamp (cfl)

So all are switching less than 1Amp, but I was conscious of any potential inrush current.



I\'m now waiting for you to tell me the RLY01B\'s I am using to switch our other lights are not suitable for the job either...

Not feeling the love this end.
I\'m a great supporter of the comfort system, had it for close on 20 years, evolving and updating it over time, but this makes me question the suitability of my installation.

I had intended to replace a bunch of my lighting control with these but held off. Glad I did now...

Sorry if this seems like a rant, but I spent a bunch of time making sure I made the right choices. If I hadn\'t had this problem I would be totally oblivious of your statement that they aren\'t suitable for mains switching...

I\'m pleased to see you finally got the Din mounted IRIO-IO and RLE-02 out.

Send me a price for both, I can\'t see them on the laser web site. If I were to use these in the cabinet above, how are they any better than what I have ?

Can I connect the RLE-02 to a normal IRIO, or must it be an IRIO-IO?
I suspect the latter due to the new connectors not on the IRIO-IO.

On a different note, Can the TWS control 4 independent lights, or are the channels / relays interconnected such that one is on & the other off.

Other than moisture creating the problem, other posibilities elctrical strands faulty components the list could be potentialy endless the boards touching, but from what i can see the fault lies in arcing (shorting out). other than what I have said and seen I could not suggest anything at all.

Swiss-Toni Thanks again for your replies.
The boards don\'t touch, their distance is governed by the connectors.There were/are no strands floating about.
I will give the cabinet a good clean, and check the heater is actually working, as that\'s the only thing aside from the board substrate or connector breaking down I can think of. Oh, and check the vent is not blocked.
The only thing above this board is the loop of the grey cat5 cable.
I have some things to try, then decide how best to proceed.
Thanks again.

Relays are not just meant to switch mains voltage. They give dry contact  to any equipmenty for example auto-gates, electronic door locks, blinds, garage openers etc
However it is true that we have not given sufficient warning that mains voltage should not be switched with ISM06 and ISM07 because of the proximity to the electronic circuits so I apologise for the oversight. I will send a PM about our offer for the IRIO/RLE as replacement. RLE02 is used with IRIO-IO but it also has 12V inputs that can be used with other products including IRIO01
RLY01H can be used to switch mains voltage because there is not any circuitry on the board. However you must ensure that it is mounted correctly and the mains cables arr not in danger of contacting other circuits

IRIO-TWS controls 4 independent lights. I suggest this if you mean to control On/Off lights

[John W]

Thanks for your reply.

I just checked and as yet don\'t have any PM from you.

Prices for each would be good please.
Also, can you confirm please whether the ISM04 two way switch module can be used to switch mains 240v lighting ?This is what is suggested in the description, and shown by the diagrams, yet this module doesn\'t have the logic separation you mention above either.Just checking as I have these in my installation too...

Sorry, have not been abe to send yet, but will do later
ISM04is not a product that is sol
In fact IRIO-TWS is actually 2 ISM04 and IRIOso ISM04 is used when programing IRIO-TWS

Please check your email

Thank you.
Received it, will reply later.
