Hi, I'm working on a project where I need to use a couple of relays to send an input signal back to the controller. I'm using the 24V supply voltage from the controller to power a spdt switch, but I noticed that if I keep the switch powered for awhile, it gets hot to the touch. The specs for the switch are... Product Height 1 DC Coil Voltage 12 Coil Resistance 270 Max Current Rating 5 Max AC Voltage Rating 250 Max DC Voltage Rating 30 Average Bias Current-Max (IIB)(uA) .003 I know that some components will get a little hot when running under normal conditions, but I guess I'm just not sure if I'm overloading the switch. The specs say that the DC Coil Voltage is 12V, but the Max DC voltage is 30V. Does this mean I can put 30V across the coil and be fine? My next step is going to be measuring the current through the coil when operating, but what kind of calculations or otherwise should I do with that? As long as the current is under 5A, I should be good right? Thanks for the help!
