2 Relay on PaHub

[mad23]

Hello everyone, I would like to switch the relay separately using PaHub 2 and can't get any further. Does anyone have an example here of using the PaHub with Relay?

Hello @mad23

Pa.Hub is an I2C extension hub so unless your relays use I2C (which I doubt) you cannot use a Pa.Hub to connect and switch two relays.

Did you mean Pb.Hub?

Thanks

Would the PbHub be used for this application?

Hello @mad23

I'd say so, yes, but I don't have a Pb.Hub so I cannot say for sure, sorry.

@all: maybe somebody who owns a Pb.Hub can help out here?

Thanks
Felix

You should be able to run up to 5 relay units connected to the i/ohub (pbhub).
