OR
Note: User must set
to “OR” if only one
input source is being
used.
LATCH
None
AND -Turns digital output ON when input IN A
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 - Monitors Input A Source and Input B
Source to set state of digital output signal.
If A = OFF and B = OFF, then OUT = OFF.
If A = ON and/or B = ON, then: OUT = ON.
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.

On Delay 0 to 120 seconds
default = 0.0
An on-delay time value up to 120 seconds is
available to prevent momentary logic gate output
actions. Number of seconds the logic gate is true
before activating the Output.
