S = a AND b S = a. b <T2>YES element</T2> The output signal "S" is only present when the pilot is present : S = a YES b S = a <T2>NOT element</T2> The output signal "s" is present only if the input signal "a" is NOT present. The output signal is therefore the inverse of the pilot signal. S = NOT a S = a If the supply port is connected to a 2nd input "b", the function obtained is called Inhibition. S = NOT a AND b S = a. b Dimension Diagram : 81 540 001 - 81 541 001 : OR element The output signal "S" is present when a signal at "a" OR "b" is present S = a OR b S=a+b 20/05/2011
