Allen-Bradley SAN4-40M is a four-channel safety relay module designed to monitor and interlock multiple safety circuits in industrial automation. It provides four independent safety channels that can be wired to safety devices such as emergency stops, safety interlocks, and other sensors to help ensure controlled machine stoppage and safe reset sequences. This SAN4-40M unit consolidates four relays in a single module, simplifying wiring and integration into safety control schemes.
