The idea has been taken from http://www.techjava.de/topics/2014/01/basement-drainage-pump-control-and-iot/ I have an automatic pump like http://www.valco.eu/sitemanager/file/r_4_installation-dernajo-liqua_1.jpg I control the current and if it is out from specific range for a specific time I switch off the pump and send an alarm. To control the current i use amp clamp but to switch off I need a more powerful relay ThinkerForge has a Dual Relay Bricklet but support not enough Amp (when pump self start ) drained by pump. There is a Solid State Relay AC 380V/25A but I'm worry about Temp. Is the possibility to use a relay like a SONGLE SLA 05 S L C. Or something to substitute to the solded relay or the PCB has to be rebuild. Zitieren Link zu diesem Kommentar Share on other sites More sharing options...

With this setup you can buy a big relay that can handle your pump easily and the Tinkerforge stuff is galvanically isolated from the switching itself!
