Allen-Bradley 1440 Series Technical Notes

The Evolution of 1440 Series Architecture

The 1440 Series was introduced as Rockwell Automation's response to the need for a standards-compliant, network-integrated TSI platform. Early revisions (suffix -00RA, -01RA) established the core hardware architecture: isolated analog front-ends, onboard signal conditioning, and a backplane communication bus compatible with the 1440 chassis. These initial variants supported basic vibration and speed measurement with local relay outputs for alarm and trip functions.

Subsequent hardware revisions (-01RB, -04RB, -06RB) introduced enhanced firmware, improved EMI immunity, and expanded channel density. The communication architecture evolved from proprietary backplane protocols to full EtherNet/IP support via the 1440-ENBTA gateway modules, enabling the 1440 Series to participate in plant-wide data historian and condition monitoring architectures. Later variants incorporated onboard diagnostics, self-test routines, and improved transient capture buffers for machinery event recording.
