| Re: control circuits Certain authauritys do indeed have certain voltages for control circuits in they're specs, sometimes the colour of the wiring denotes the voltage, ie red for 240, black for 100, orange for 24 ac, white for 24v dc and grey for 12v. Beware though, 24V AC can still put somone on they're arse ! (been there. Ouch !) The lower the voltage the better for remote controls as in my experiance, cleaning companys will hose down just about anything, electrical or otherwise. I forget the amount of times I have had to dry out temerature controller, timers, chart recorders, even DB's ! |
