Logic 1	Type	None (default)	None
Logic 2		AND	AND -Turns digital output ON when input IN A
Logic 3
Logic 4			Source and IN B Source are ON. Thus,
			If all inputs are ON, then: OUT = ON.
			If any input is OFF, then: OUT = OFF.
		OR	OR - Monitors Input A Source and Input B
		Note: User must set	Source to set state of digital output signal.
			If A = OFF and B = OFF, then OUT = OFF.

		used.
		LATCH		LATCH – Sets and Resets Latch state of the
				Output.
				If A=ON, B=OFF The Output is Latched ON.
				If A=OFF, B=ON, The Output is Latched OFF.
				If A and B are ON the Output = ON
				If A and B are OFF the Output = Latch State.
			Power On considerations. The output state of the
			latch is cleared on power on.

	Invert	None (default)	You can invert Input A or Input B or both. If the
		IN A	input is inverted, an input line that is ON is seen
		IN B	as OFF
		In A and B
	On Delay	0 to 120 seconds	An on-delay time value up to 120 seconds is
