About the 1769-BOOLEAN
Module The 1769-BOOLEAN module is a 24V dc combination input/output module.
The module outputs can be either directly controlled from your program or
independently controlled by the module using configured Boolean
expressions. These Boolean expressions are simple, logical combinations of
the module hardware input states and soft inputs controlled by your program.
When controlled by Boolean expression, the 1769-BOOLEAN module output
states can be conditioned using configured delay and duration settings. The
1769-BOOLEAN module supports interrupts to the system controller on
both input and output change of states

The Compact I/O system is suitable for use in an industrial environment
when installed in accordance with these instructions. Specifically, this
equipment is intended for use in clean, dry environments (Pollution degree
2
(2)
) and to circuits not exceeding Over Voltage Category II
(3)
(IEC
60664-1)

.
(1) Interrupts from the module to the controller may not be supported by all controllers. Refer to your controller's
user manual for more information.
(2) Pollution Degree 2 is an environment where, normally, only nonconductive pollution occurs except that occasionally a
temporary conductivity caused by condensation is expected.
(3) Over Voltage Category II is the load-level section of the electrical distribution system. At this level, transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(4) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.
