Allen-Bradley 1719-ARM Programmable Logic Controller Module

The Allen-Bradley 1719-ARM is an Ex I/O empty-slot placeholder designed to cover unused positions in 1719 Ex I/O adapters within a Rockwell Automation 1719 Ex I/O system. As a member of the 1719 Ex I/O family, it serves as an official placeholder module to seal off vacant slots, with installation guidance noting that unused slots can be left empty or covered using the 1719-ARM. The part carries UPC 889508013459, has an estimated lead time of 5 days, and comes with a standard 1-year warranty, with country of origin listed as multiple. It is not an I/O module and provides a physical cover to maintain enclosure integrity and safety when fewer I/O modules are installed in the chassis.
