Overview
The Allen-Bradley 440S-SF5D is a five-pin OSSD (output signal switching device) GuardLink enabled tap from Rockwell Automation. GuardLink taps connect safety input devices to a GuardLink system, a safety-based communications protocol that links safety to The Connected Enterprise, and GuardLink enabled devices offer advanced features and diagnostics that can only be accessed through a GuardLink enabled connection tap.
