1794-IB16D Diagnostic Input Module Compatibility

The 1794-IB16D diagnostic input module interfaces to sensing devices and
detects whether they are on or off. The diagnostic input module converts DC
signals from user devices to the appropriate logic level for use in the FLEX I/O
system. Typical input devices include these types of switches.
• Proximity switches
• Limit switches
• Photoelectric switches
• Selector switches
• Float switches
• Push button switches
When designing a system using a FLEX I/O diagnostic input module, you must
consider:
• the voltage necessary for your application.
• current leakage through the input devices.
• the amount of current consumed by the input devices.
• whether the application requires sinking or sourcing devices.
