FOXBORO 2AX-ALM-AR Product Brief Description

The FOXBORO 2AX-ALM-AR is a dual absolute alarm relay module for Foxboro I/A Series legacy DCS system. It monitors analog process variables and provides two independent absolute alarm relay outputs. When measured values exceed predefined setpoints, the module activates relay contacts to drive local alarms or trigger interlock actions. It is a plug-in backplane card designed for stable alarm handling in continuous process control environments.
