Increasing Relay Output Current

I'm not great when it comes to electronics so i hope this makes sense.
I'm looking to use a zelio logic 2 module to control two 20w 24vdc solenoid valves. The output from the device is stated as ">= 10 mA at 12 V (relay output)". I'm assuming i need something to boost the current for use with the solenoids? What is the best way to do this?

Got a datasheet or part number for the specific module you are using?
The one I see says the relay outputs can do up to 8 Amps..

Says you can switch up to 8A..
switching current must be "greater" than 10mA..

You should be able to use AS IS to switch your solenoid..

Brilliant thanks for the help. It said "output thermal current" so i wasn't quite sure what it meant.
Personally I don't really either.. :) Thats some silly "Schneider" technical term that only their technical writer knows what it really means.. and the rest of us just make an educated guess.

I'd guess that the intent of that is to ensure that the total current through all 4 relays does not exceed 8 Amps due to heating from relay/contact dissipation.

So all is good if all 4 outputs are switching 2A
or 1 switching 8A
or 2 switching 4A
,etc...

no problems IMO..
Seems like just a switched output..
level low = no output voltage
level high = output voltage..
