Current flow between S1 and SX terminals


Guest pagewrite
 Share

Question

Guest pagewrite

Does anyone know the current flow (therefore, cable requirements) that flows between the S1 and SX terminals of the Fibaro dimmer and relay modules? There's not enough space in the wall box to to accommodate the module, and am therefore going to mount it remotely. Just be useful to know if I can use smaller cabling than the load-carrying conductors.

Thanks!

Ian

I think you can use smaller cable with no problem. I use 1/10 cable with micro switch in few homemade.

I have measured this just out of curiosity and it seemed to be over 130-150Volts, I do not know how many ampers.

We wanted to know if it is possible to use cat5 (internet cable) to trigger modules (sx and s1;s2). It didnt seem to be a good idea after measurement.

CAT5 can easily handle 45-55 Volts and 12-24W (cf. POE) and you can use several pairs at once but I guess you want to use CAT 5 just to use several modules at the same time?

I didnt try dimmering, but just turning lights on-off smoothly (as dimmer default is) there was current over 130volts easily..

We had some technical questions with knx system vs fibaro and wanted to know if we can use knx cable to connect Sx to S1 to turn on/off lights.

SX 0,2mA

S1 0,2mA

but what about current? Is CAT5 cable and 220V with 0,2mA okay?

I asked the question and I expect the answer ...

The Full response:

SX 0,2mA

S1 0,2mA

and for maximum voltage is ...

that same like on "L"

Sx=S1= L

I think yes, only with monostable switch and quick contact but it seems not good for dimmer...

  • Thanks for everyone's response. Kind of what I was expecting - probably 220v, but only a very small current. At least I don't need to use twin and earth cable for the switching cabling, which is good - even if alarm or Cat 5 may be unwise! Hopefully this allows me to make some fancy switches, now I have the entire back box space to play with...

    Actually i checked around and cat5 cable is rated for 60V AC and 120V DC, so 220V AC is not very good, because the isolation is not enough.

    Please do not burn down the house

  • I use a AWG24 20cm cable to connect Sx and S1 - S2 to my switch; because they are smaller and had not enough place to put 1,5mm² cable.

    It work fine ; but now i ask me if there could be some problems or risk of fire ?...

    What do you think ?
