I have a small greenhouse and want to use an Ocelot and a SECU16 to fill water barrels in the greenhouse with house water. I do not want the electronics in the greenhouse because of the wet and humid environment. I have also had problems in the past with interference from motor driven foggers interacting with the electronics. Each night I want to refill the barrels using a 24V valve and monitor them with float switches. If I keep the electronics in the house and run 50 feet of cable from the SECU16 to the greenhouse and attach to the floats, will this work? Should this be terminated with a resistor?
