Allen-Bradley 800H-2HAR Programmable Logic Controller Module

Allen-Bradley 800H-2HAR is a 30 mm push-button station in Rockwell Automation's Bulletin 800H family, designed to provide operator input in local control panels and machine enclosures. The 800H line comprises 30 mm push-button assemblies, and the 800H-2HAR designation appears on variants such as 800H-2HAR4T and 800H-2HAR4R that show different termination and enclosure configurations; these models are listed by Rockwell as active catalog items. Common applications include manual start/stop and other operator-control interfaces in manufacturing equipment and conveyors. Rockwell literature confirms that 800H push-button stations can be configured for Type 4/13 ratings in appropriate assemblies, supporting use in harsh industrial environments when installed in compatible enclosures.
