Compatibility
Primarily, this module is used to interface to sensing devices and detect
whether they are ON or OFF and to timestamp ON and OFF transitions. The
module converts ON/OFF signals from user devices to appropriate logic level
for use in the processor. Typical input devices include:
• auxiliary contacts
• limit switches
When designing a system using these modules, you must consider:
• the voltage necessary for your application
• whether you need a solid state device
• current leakage
• if your application should use sinking or sourcing wiring.
For more information on compatibility of other Rockwell Automation
products to modules, see the I/O Systems Overview, publication CIG-SO001
.
There are two types of features available on the module:
• Module Features That Can Be Configured - Features that can be
adjusted to make sure the module operates as efficiently as possible in
your application (for example., input filter times)
• Other Inherent Module Features - Features that cannot be changed but
are still crucial to module functionality (for example,
producer/consumer model).
