What is the ControlLogix
High-speed Analog I/O Module?
The ControlLogix high-speed analog I/O module is an interface module that
converts analog signals to digital values for inputs and converts digital values to
analog signals for outputs. Using the producer/consumer network model, the
module produces information when needed while providing additional system
functions.
Available Features
The following are some of the features available on the module:
• Input Synchronization—This feature lets you synchronize the sampling of
inputs across multiple fast analog modules in the same chassis, allowing
those inputs to sample at the same rate within microseconds of each other.
For more information, see Synchronize Module Inputs
on page 45.
• Combination module offering 4 differential inputs and 2 outputs
• Sub-millisecond input sampling
• One millisecond output updates
• On-board alarms and scaling
• Removal and insertion under power (RIUP)
• Producer/consumer communication
• Rolling timestamp of data in milliseconds
• Coordinated System Time (CST) timestamp of data in microseconds
• IEEE 32 bit floating point
• Class I/Division 2, UL, CSA, CE, and C-Tick Agency Certification
