Crouzet Or Gate-Blue-Sub-base Mounted

2.7mm orifice, 170 L/min. Greater than 107 operations. Function: OR Element The output signal "S" is present when a signal at "a" OR "b" is present. S = a OR b. AND Element The output signal "S" is present only when signals "a" AND "b" are present simultaneously. S = a AND b. YES Element The output signal "S" is only present when the pilot is present. S = a YES b. NOT Element 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. If the supply port is connected to a 2nd input "b" the function obtained is called Inhibition. S=NOT a AND b. Note: Switching time = <4ms exception OR and AND.
